SPM and Task error ...
by Enrico 22 Nov '24

22 Nov '24

Hi all, my ovirt cluster has got 3 Hypervisors runnig Centos 7.5.1804 vdsm is 4.20.39.1-1.el7, ovirt engine is 4.2.4.5-1.el7, the storage systems are HP MSA P2000 and 2050 (fibre channel). I need to stop one of the hypervisors for maintenance but this system is the storage pool manager. For this reason I decided to manually activate SPM in one of the other nodes but this operation is not successful. In the ovirt engine (engine.log) the error is this: 2019-07-25 12:39:16,744+02 INFO [org.ovirt.engine.core.bll.storage.pool.ForceSelectSPMCommand] (default task-30) [7c374384-f884-4dc9-87d0-7af27dce706b] Running command: ForceSelectSPMCommand internal: false.

Changing disk QoS causes segfault with IO-Threads enabled (oVirt 4.3.0.4-1.el7)
by jloh＠squiz.net 23 Apr '24

23 Apr '24

We recently upgraded to 4.3.0 and have found that when changing disk QoS settings on VMs whilst IO-Threads is enabled causes them to segfault and the VM to reboot. We've been able to replicate this across several VMs. VMs with IO-Threads disabled/turned off do not segfault when changing the QoS. Mar 1 11:49:06 srvXX kernel: IO iothread1[30468]: segfault at fffffffffffffff8 ip 0000557649f2bd24 sp 00007f80de832f60 error 5 in qemu-kvm[5576498dd000+a03000] Mar 1 11:49:06 srvXX abrt-hook-ccpp: invalid number 'iothread1' Mar 1 11:49:11 srvXX libvirtd: 2019-03-01 00:49:11.116+0000: 13365: error : qemuMonitorIORead:609 : Unable to read from monitor: Connection reset by peer Happy to supply some more logs to someone if they'll help but just wondering whether anyone else has experienced this or knows of a current fix other than turning io-threads off. Cheers.

oVirt host deploy: disable multipath

27 Mar '23

https://bugzilla.redhat.com/show_bug.cgi?id=1472356 There are 2 drives in my install that oVirt is claiming as multipath. I have tried blacklisting at /etc/multipath/ but that hasn't worked. Any better solutions? I need these 2 drives to be non-multipathed.

Network Address Change
by Paul.LKW 28 Dec '22

28 Dec '22

Hi All: I just has a case, I need to change the oVirt host and engine IP address due to data center decommission I checked in the hosted-engine host there are some files I could change ; in ovirt-hosted-engine/hosted-engine.conf ca_subject="O=simple.com, CN=1.2.3.4" gateway=1.2.3.254 and of course I need to change the ovirtmgmt interface IP too, I think just change the above line could do the tick, but where could I change the other host IP in the cluster ? I think I have to be lost all the host as once changed the hosted-engine host IP as it is in diff. sub net. Does there any command line tools could do that or someone has such experience could share? Best Regards, Paul.LKW

looking for some ISV backup software which integrates the backup API
by Nathanaël Blanchet 08 Jun '22

08 Jun '22

Hello, We are about to change our backup provider, and I find it is a great chance to choose a full supported ovirt backup solution. I currently use this python script vm-backup-scheduler (https://github.com/wefixit-AT/oVirtBackup) but it is not the workflow officially suggested by the community (https://www.ovirt.org/develop/release-management/features/storage/backup-re…) I've been looking for a long time an ISV who supports such an API, but the only one I found is this one : Acronis Backup Advanced suggested here https://access.redhat.com/ecosystem/search/#/ecosystem/Red%20Hat%20Enterpri… I ran the trial version, but it doesn't seem to do better than the vm-backup-scheduler script, and it doesn't seem to use the backup API (attach a clone as a disk to an existing vm). Can you suggest me some other ISV solutions, if they ever exist... or share me your backup experience?

OVS switch type for hosted-engine
by Devin A. Bougie 06 May '22

06 May '22

Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If it's not possible to start out as OVS, instructions for switching from Legacy to OVS after the fact would be greatly appreciated. Many thanks, Devin

USB3 redirection
by Rik Theys 19 Apr '22

19 Apr '22

Hi, I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1 with USB redirection enabled. I've created the following file in /etc/ovirt-engine/osinfo.conf.d: 01-usb.properties with content os.other.devices.usb.controller.value = nec-xhci and have restarted ovirt-engine. If I disable USB-support in the web interface for the VM, the xhci controller is added to the VM (I can see it in the qemu-kvm commandline), but usb redirection is not available. If I enable USB-support in the UI, no xhci controller is added (only 4 uhci controllers). Is there a way to make the controllers for usb redirection xhci controllers?

OVN routing and firewalling in oVirt
by Gianluca Cecchi 19 Apr '22

19 Apr '22

Hello, how do we manage routing between different OVN networks in oVirt? And between OVN networks and physical ones? Based on architecture read here: http://openvswitch.org/support/dist-docs/ovn-architecture.7.html I see terms for logical routers and gateway routers respectively but how to apply to oVirt configuration? Do I have to choose between setting up a specialized VM or a physical one: is it applicable/advisable to put on oVirt host itself the gateway functionality? Is there any security policy (like security groups in Openstack) to implement? Thanks, Gianluca

Host needs to be reinstalled after configuring power management
by Andrew DeMaria 02 Feb '22

02 Feb '22

Hi, I am running ovirt 4.3 and have found the following action item immediately after configuring power management for a host: Host needs to be reinstalled as important configuration changes were applied on it. The thing is - I've just freshly installed this host and it seems strange that I need to reinstall it. Is there a better way to install a host and configure power management without having to reinstall it after? Thanks, Andrew

Import an exported VM using Ansible
by paolo＠airaldi.it 25 Jan '22

25 Jan '22

Hello everybody! I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook. I'm able to: - Create a snapshot of the source VM - create a clone from the snapshot - remove the snapshot - attach an Export Domain - export the clone to the Export Domain - remove the clone - detach the Export domain from the source Datacenter and attach to the destination. Unfortunately I cannot find a module to: - import the VM from the Export Domain - delete the VM image from the Export Domain. Any hint on how to do that? Thanks in advance. Cheers. Paolo PS: if someone is interested I can share the playbook.

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com 02 Sep '21

02 Sep '21

I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server. I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template. When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template. It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue. Has anyone else noticed this behavior? Is this expected or have I missed something? Thanks for your input!

Libgfapi considerations
by Jayme 01 Jul '21

01 Jul '21

Are there currently any known issues with using libgfapi in the latest stable version of ovirt in hci deployments? I have recently enabled it and have noticed a significant (over 4x) increase in io performance on my vms. I’m concerned however since it does not seem to be an ovirt default setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

So I'm thinking it's resource exhaustion or a leak of some kind? Running 4.2.8.2 with VDSM at 4.20.46. I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix. Thanks, Alan

OVN and change of mgmt network
by Gianluca Cecchi 26 Jan '21

26 Jan '21

Hello, I previously had OVN running on engine (as OVN provider with northd and northbound and southbound DBs) and hosts (with OVN controller). After changing mgmt ip of hosts (engine has retained instead the same ip), I executed again on them the command: vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host> Now I think I have to clean up some things, eg: 1) On engine where I get these lines below systemctl status ovn-northd.service -l . . . Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp: 10.4.167.40:37272: no response to inactivity probe after 5 seconds, disconnecting Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp: 10.4.167.41:52078: no response to inactivity probe after 5 seconds, disconnecting The two IPs are the old ones of two hosts It seems that a restart of the services has fixed... Can anyone confirm if I have to do anything else? 2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34) where I currently have this output [root@ov301 ~]# ovs-vsctl show 3a38c5bb-0abf-493d-a2e6-345af8aedfe3 Bridge br-int fail_mode: secure Port "ovn-1dce5b-0" Interface "ovn-1dce5b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.32"} Port "ovn-ddecf0-0" Interface "ovn-ddecf0-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.33"} Port "ovn-fd413b-0" Interface "ovn-fd413b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.168.74"} Port br-int Interface br-int type: internal ovs_version: "2.7.2" [root@ov301 ~]# The IPs of kind 10.4.192.x are ok. But there is a left-over of an old host I initially used for tests, corresponding to 10.4.168.74, that now doesn't exist anymore How can I clean records for 1) and 2)? Thanks, Gianluca

encrypted GENEVE traffic
by Pavel Nakonechnyi 18 Jan '21

18 Jan '21

Dear oVirt Community, From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/) Are there plans to introduce such support? (or explicitly not to..) Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way) Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic. Such requirement arises when using oVirt deployment on third-party premises with untrusted network. Thank in advance for any clarifications. :) -- WBR, Pavel +32478910884

"gluster-ansible-roles is not installed on Host" error on Cockpit
by Hesham Ahmed 26 Nov '20

26 Nov '20

On a new 4.3.1 oVirt Node installation, when trying to deploy HCI (also when trying adding a new gluster volume to existing clusters) using Cockpit, an error is displayed "gluster-ansible-roles is not installed on Host. To continue deployment, please install gluster-ansible-roles on Host and try again". There is no package named gluster-ansible-roles in the repositories: [root@localhost ~]# yum install gluster-ansible-roles Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist, package_upload, product-id, search-disabled-repos, subscription-manager, vdsmupgrade This system is not registered with an entitlement server. You can use subscription-manager to register. Loading mirror speeds from cached hostfile * ovirt-4.3-epel: mirror.horizon.vn No package gluster-ansible-roles available. Error: Nothing to do Uploading Enabled Repositories Report Cannot upload enabled repos report, is this client registered? This is due to check introduced here: https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js Changing the line from: [ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" } to [ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" } resolves the issue. The above code snippet is installed at /usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g' /usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart cockpit"

deprecating export domain?
by Charles Kozler 30 Aug '20

30 Aug '20

Hello, I recently read on this list from a redhat member that export domain is either being deprecated or looking at being deprecated To that end, can you share details? Can you share any notes/postings/bz's that document this? I would imagine something like this would be discussed in larger audience This seems like a somewhat significant change to make and I am curious where this is scheduled? Currently, a lot of my backups rely explicitly on an export domain for online snapshots, so I'd like to plan accordingly Thanks!

Support for Shared SAS storage
by Vinícius Ferrão 13 Aug '20

13 Aug '20

Hello, I’ve two compute nodes with SAS Direct Attached sharing the same disks. Looking at the supported types I can’t see this on the documentation: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html There’s is local storage on this documentation, but my case is two machines, both using SAS, connected to the same machines. It’s the VRTX hardware from Dell. Is there any support for this? It should be just like Fibre Channel and iSCSI, but with SAS instead. Thanks,

oVirt thrashes Docker network during installation
by thomas＠hoberg.net 30 Jul '20

30 Jul '20

I want to run containers and VMs side by side and not necessarily nested. The main reason for that is GPUs, Voltas mostly, used for CUDA machine learning not for VDI, which is what most of the VM orchestrators like oVirt or vSphere seem to focus on. And CUDA drivers are notorious for refusing to work under KVM unless you pay $esla. oVirt is more of a side show in my environment, used to run some smaller functional VMs alongside bigger containers, but also in order to consolidate and re-distribute the local compute node storage as a Gluster storage pool: Kibbutz storage and compute, if you want, very much how I understand the HCI philosophy behind oVirt. The full integration of containers and VMs is still very much on the roadmap I believe, but I was surprised to see that even co-existence seems to be a problem currently. So I set-up a 3-node HCI on CentOS7 (GPU-less and older) hosts and then added additional (beefier GPGPU) CentOS7 hosts, that have been running CUDA workloads on the latest Docker-CE v19 something. The installation works fine, I can migrate VMs to these extra hosts etc., but to my dismay Docker containers on these hosts lose access to the local network, that is the entire subnet the host is in. For some strange reason I can still ping Internet hosts, perhaps even everything behind the host's gateway, but local connections are blocked. It would seem that the ovritmgmt network that the oVirt installation puts in breaks the docker0 bridge that Docker put there first. I'd consider that a bug, but I'd like to gather some feedback first, if anyone else has run into this problem. I've repeated this several times in completely distinct environments with the same results: Simply add a host with a working Docker-CE as an oVirt host to an existing DC/cluster and then try if you can still ping anyone on that net, including the Docker host from a busybox container afterwards (should try that ping just before you actually add it). No, I didn't try this with podman yet, because that's separate challenge with CUDA: Would love to know if that is part of QA for oVirt already.

Shutdown procedure for single host HCI Gluster
by Gianluca Cecchi 25 Jul '20

25 Jul '20

Hello, I'm testing the single node HCI with ovirt-node-ng 4.3.9 iso. Very nice and many improvements over the last time I tried it. Good! I have a doubt related to shutdown procedure of the server. Here below my steps: - Shutdown all VMs (except engine) - Put into maintenance data and vmstore domains - Enable Global HA Maintenance - Shutdown engine - Shutdown hypervisor It seems that the last step doesn't end and I had to brutally power off the hypervisor. Here the screenshot regarding infinite failure in unmounting /gluster_bricks/engine https://drive.google.com/file/d/1ee0HG21XmYVA0t7LYo5hcFx1iLxZdZ-E/view?usp=… What would be the right step to do before the final shutdown of hypervisor? Thanks, Gianluca

How to connect to a guest with vGPU ?
by Josep Manel Andrés Moscardó 29 May '20

29 May '20

Hi, I got vGPU through mdev working but I am wondering how I would connect to the client and make use of the GPU. So far I try to access the console through SPICE and at some point in the boot process it switches to GPU and I cannot see anything else. Thanks. -- Josep Manel Andrés Moscardó Systems Engineer, IT Operations EMBL Heidelberg T +49 6221 387-8394

Issues encountered performing HE install on 4.3
by Alan G 24 May '20

24 May '20

Hi, I hit a few issues while performing a recent HE install of 4.3. While I managed to find solutions/workarounds to all the problems I thought I might share them here * As defined in the Ansible defaults the temp dir for building the local HE VM is /var/tmp. I was 80M short of the required space and there did not appear to be a (supported) way to specify a different location. I ended up having to do a bind mount of /var/tmp to get me through the install. Would be nice to be able to specify a custom location. * Permissive umask required. Our CIS CentOS 7 build requires that default umask is 027. This breaks the installer as it creates the VM image under /var/tmp as root and cannot then access it as qemu user. As the temp files are cleaned up on failure it took me a while to track this one down. My solution was to temporarily set the umask to 022 for the session while running the installer. It would be nice if the installer either handled this by doing a chmod/chown as required, or at least doing a umask pre-check and failing with a meaningful error. * SSH root login required on host. Again for CIS we have "PermitRoologin no" configured in sshd. This means the add host task fails on the Engine, but instead of a hard failure we get a timeout on the installer. Which left me chasing some imagined routing/bridging/DNS issue. Eventually I realised I could get to the engine logs and found the issue but took several hours. Would be nice if the installer could either support a sudo option or at least perform a root login pre-check and fail with a meaningful error. Thanks, Alan

Upgrade scenario to 4.4 for HCI Gluster
by Gianluca Cecchi 11 May '20

11 May '20

Hello, I saw from some mails in the list that the approach for upgrading from 4.3 to 4.4 will be similar to the 3.6 => 4.0 one. Reading the RHV 4.0 Self Hosted Engine Guide it seems it was necessary to have a second host, going through this: 5.4. Upgrading a RHEV-H-Based Self-Hosted Engine Environment https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.0/ht… and also https://www.ovirt.org/develop/release-management/features/sla/hosted-engine… upgrade process involved: - set global ha maintenance - install a new host (and set it as on hosted engine one) - migrate engine VM to this host and set the host as the SPM - create a backup with engine-backup, verify its contents and copy to the host in some directory - run the upgrade utility on the host to update the engine VM hosted-engine --upgrade-appliance this will create a backup floating disk of the engine vm disk for rollback purposes and override the existing engine disk with a new one where to deploy the new engine version applying also the restore from the engine-backup --> what are requirements for 4.4 engine VM and so free storage to have on engine storage domain? The engine-setup will be automatically executed on the new version engine VM - exit from global maintenance - update remaining hosts Is the above procedure the correct one that I can test on a 4.3.9 lab? The 3.6 -> 4.0 flow implied that a 4.0 host could run a 3.6 engine VM Because the backup disk operation is done by the current running engine itself. So it should be true also for 4.3 -> 4.4 and a 4.4. host should be able to run a 4.3 engine, correct? In case of single 4.3.9 ovirt-node-ng host HCI with Gluster, can I apply the upgrade in a similar way? Something like: - create engine-backup and copy over to the host - put host into global maintenace - shutdown all VMS, engine included - enable 4.4. repo - install new image-base 4.4 is this correct and I can use 4.3 and 4.4 image base versions or do I have to sort-of-scratch necessarily? because 4.3 host is based on el7 while 4.4 on el8... but perhaps on mage based system I have flexibility..? what version of gluster will it be applied? Incompatibilities with the current 4.3.9 one (version 6.8-1.el7) - reboot host - exit global maintenance and wait for engine vm to come up correctly - enter global maintenance again - run the upgrade utility on the host Or do I need at least temporarily a new server to use as the 4.4. host, or what will be the expected path? Thanks, Gianluca

07 May '20

I'm using oVirt 4.3 (latest ) and able to successfully provision Centos VMs without any problems. When I attempt to provision Ubuntu VMs, they hang at startup. The console shows : ... ... [ 4.010016] Btrfs loaded [ 101.268594] random: nonblocking pool is initialized It stays like this indefinitely. Again, I have no problems with Centos images, but need Ubuntu Any tips greatly appreciated.

Backup software recommendations
by Colin Coe 06 May '20

06 May '20

Hi all I'm looking for recommendations for backup software. It needs to handle physical and virtual Linux and Windows, RHV and Hyper-V. It doesn't have to be open source and it doesn't have to be free. The main features we need are: - disk to disk backups - inter-site replication with rate limiting - be able to handle Linux thin volumes (think RHGS) - support BMR ans granular file / directory restore - correctly handle Windows VSS - support RHEL point releases as soon as they are released I'm as much after "stay away from" as recommendations. We currently use Arcserve UDP and it is ... well ... sub optimal Thanks in advance CC

oVirt 4.4.0 Beta release refresh is now available for testing The oVirt Project is excited to announce the availability of the beta release of oVirt 4.4.0 refresh (beta 4) for testing, as of April 17th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. Important notes before you try it Please note this is a Beta release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not to be used in production. In particular, please note that upgrades from 4.3 and future upgrades from this beta to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Beta require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Known Issues - ovirt-imageio development is still in progress. In this beta you can’t upload images to data domains using the engine web application. You can still copy iso images into the deprecated ISO domain for installing VMs or upload and download to/from data domains is fully functional via the REST API and SDK. For uploading and downloading via the SDK, please see: - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_d… - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download… Both scripts are standalone command line tool, try --help for more info. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Beta? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support only for file based storage. iSCSI/FC storage do not support 4k disks yet. - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Engine UI exception while viewing unattached hosts in Network tab
by Shareef Jalloq 03 May '20

03 May '20

Hi, I'm following the Gluster setup blog post ( https://blogs.ovirt.org/2018/02/up-and-running-with-ovirt-4-2-and-gluster-s…) and am at the 'Storage network' section. I've created a new 'gluster' network, selected the network and navigated to the 'Hosts' tab. The guide tells you to click the 'Unattached' button and then 'Setup Host Networks' for each host. However, clicking the 'Unattached' button fires off a bunch of exceptions rather than displaying my 3 hosts. The message is: "Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'N' of null Please have your administrator check the UI logs" Anyone seen this before? Where is the UI log located? Shareef.

Unable to remove system roles from Everyone group
by miguel.garcia＠toshibagcs.com 02 May '20

02 May '20

I opened Everyone group and added system role UserRole and realized now that everybody can see all VMS which is not good. I tried to remove the role from the group but got the error "Error while executing action: It's not allowed to remove system permissions assigned to built-in Everyone group" Looking into Ovirt forums I see that this change should be made through the engine database but I was not able to reach that part. Can someone help me out how to remove the system role from Everyone group? or at least reset the group?

Hi, I was looking in the past 2 weeks email landing on this mailing list and a common thing I notice is that it's hard to understand which version of the involved software they're referring too. Can we agree on adding at the top of the message a couple of line like output of yum -q list installed centos-release ovirt-release\* ovirt-engine redhat-release vdsm glusterfs centos-release.x86_64 7-7.1908.0.el7.centos glusterfs.x86_64 6.8-1.el7 ovirt-engine.noarch 4.3.9.4-1.el7 ovirt-release43.noarch 4.3.9-1.el7 It will help understanding if the help request is something that may be already known, a regression, and so on. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>* <https://www.redhat.com/en/summit?sc_cid=7013a000002D2QxAAK>* *Red Hat respects your work life balance.

ovrt node ng 4.4 different fs layout and error if changed
by Gianluca Cecchi 29 Apr '20

29 Apr '20

Hello, In CentOS 7 default filesystem in anaconda was xfs, but in ovirt node ng 4.3.9 (based on CentOS 7) the default layout was set to ext4. In CentOS 8 again the default is xfs and I see that ovirt node ng 4.4 beta4 (based on CentOS 8.1) has now xfs for all filesystems, excluded /boot that is set to ext4. In general I have a preference for ext4. I notice that while in 4.3.9 I could somehow customize partition layout, even if not recommended, in 4.4 I always get error if I don't accept automatic partitioning. What I sometimes do: - select disk and custom layout - click done and the storage page appears - I click the button to create automatically and I get the automatic partitioning layout - and here I can change fs type and update settings button and/or change size of some filesystems (eg for /var/log if using Gluster) Even if I only set all filesystems automatically generated by installer to ext4, without changing any size, in the final stage of installation I get this error and installation aborts: " There was an error running the kickstart script at line 5. This is a fatal error and installation will be aborted. The details of this error are: 2020-04-19 10:37:50,451 [INFO] (MainThread) Trying to create a manageable base from '/' 2020-04-19 10:37:50,811 [ERROR] (MainThread) LVM Thin Provisioning partitioning scheme is required.

Problem with multiple IP addresses and AWX
by Bernhard Dick 29 Apr '20

29 Apr '20

Hi, I've started to use awx shortly and I'd like to have an inventory based on their RHEV/oVirt-Plugin. Basically that works fine, however on machines that have multiple network interfaces or internal nets (like Docker) the first address in the IP list of the vm (which is used as ansible_host by AWX) is not an address that is reachable from the machine's outside and so those host entries are failing in my jobs. I found an issue at AWX, being like we won't fix first: https://github.com/ansible/awx/issues/1191 It also seems that there where issues related to this on oVirt: First this with a request for setting a primary IP: https://bugzilla.redhat.com/show_bug.cgi?id=1437145 And this one mentioning a way to ignore interfaces on ovirt-guest-agent, however it does no longer work due to the use of qemu-guest-agent: https://bugzilla.redhat.com/show_bug.cgi?id=1437145 Do you have any ideas how to circumvent this or is there some improvement alread in planning? Best regards Bernhard

Can't ping gluster interfaces for HCI setup
by Shareef Jalloq 29 Apr '20

29 Apr '20

Hi, I'm in the process of trying to set up an HCI 3 node cluster in my homelab to better understand the Gluster setup and have failed at the first hurdle. I've set up the node interfaces on the built in NIC and am using a PCI NIC for the Gluster traffic - at the moment this is 1Gb until I can upgrade - and I've assigned a static IP to both interfaces and also have both entries in my DNS. From any of the three nodes, I can ping the gateway, the other nodes, any external IP but I can't ping any of the Gluster NICs. What have I forgotten to do? Here's the relevant output of 'ip addr show'. em1 is the motherboard NIC and p1p1 is port 1 of an Intel NIC. The /etc/sysconfig/network-scripts/ifcfg-<if> scripts are identical aside from IPADDR, NAME, DEVICE and UUID fields. Thanks, Shareef. [root@ovirt-node-00 ~]# ip addr show 2: p1p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether a0:36:9f:1f:f9:78 brd ff:ff:ff:ff:ff:ff inet 10.0.0.34/24 brd 10.0.0.255 scope global noprefixroute p1p1 valid_lft forever preferred_lft forever inet6 fd4d:e9e3:6f5:1:a236:9fff:fe1f:f978/64 scope global mngtmpaddr dynamic valid_lft 7054sec preferred_lft 7054sec inet6 fe80::a236:9fff:fe1f:f978/64 scope link valid_lft forever preferred_lft forever 4: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 98:90:96:a1:16:ad brd ff:ff:ff:ff:ff:ff inet 10.0.0.31/24 brd 10.0.0.255 scope global noprefixroute em1 valid_lft forever preferred_lft forever inet6 fd4d:e9e3:6f5:1:9a90:96ff:fea1:16ad/64 scope global mngtmpaddr dynamic valid_lft 7054sec preferred_lft 7054sec inet6 fe80::9a90:96ff:fea1:16ad/64 scope link valid_lft forever preferred_lft forever

Do the backup on the real machine, create some isolated VM (isolated so that it does not interfere with your hosts/storage) somewhere to be used as a test host (or a physical machine if you have one), some storage somewhere, and restore on it. Make it work. Document what you needed to do. Ask here with specific questions if/when you have them. Then do on the production setup. Also clarify your needs. Do you need no-downtime for the VMs? If so, that's more complex. If you don't, it might be enough/simpler to deploy a new setup and just import the existing storage.

Hello, I see that this link below, that should be the correct one for stable virtio drivers: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-vir… points to virtio-win-0.1.171-1 released on May 2019. The same pointed by the repo https://fedorapeople.org/groups/virt/virtio-win/virtio-win.repo Under https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-vi… there are many new ones... Are so they all to be considered unstable? Thanks, Gianluca

Info about openstack staging-ovirt driver connection not released
by Gianluca Cecchi 28 Apr '20

28 Apr '20

Hello, I'm setting up an Openstack Queens lab ( to best match OSP 13) using oVirt VMs as nodes. At this time only undercloud configured and 8 Openstack nodes (VMs) set as available for provisioning. I'm using staging-ovirt driver on director node in similar way as the vbmc one. I see from oVirt active user sessions page that every minute I have one connection for node (in my case 8) of the designated user (in my case ostackpm). But it seems they are never released. How can I check the problem? Director is CentOS 7 server and the staging-ovirt driver is provided by the package: [root@director ~]# rpm -q python-ovirt-engine-sdk4 python-ovirt-engine-sdk4-4.3.2-2.el7.x86_64 [root@director ~]# I didn't configure the oVirt repo but only installed the latest stable available for 4.3.9: wget https://resources.ovirt.org/pub/ovirt-4.3/rpm/el7/x86_64/python-ovirt-engin… sudo yum localinstall python-ovirt-engine-sdk4-4.3.2-2.el7.x86_64.rpm Anyone with experience on this? In the mean time any way to use a command using api to kill the stale (I think) sessions? Thanks, Gianluca

Custom ignition in cloud-init?
by Wesley Stewart 26 Apr '20

26 Apr '20

Before anyone tells me this is now included in 4.4.0, I saw this, but I don't think I'm willing to update my centos7 host to centos8 yet. (But perhaps that will be the answer). Currently on 4.3.9/Centos 7 I am trying to run fedora core is to test it out, and the ISO installer hangs on: "failed to isolate default target freezing" So I tried the QCOW2 image, but I'm looking at ways of running the ignition file. I see in the "run once" section i can deploy a custom unit script, and I was wondering is this filetype agnostic? If I generate a JSON ignition script and put it in there will it get passed through correctly ? Or will I need to update to 4.4.0? I also found: https://gerrit.ovirt.org/#/c/100008/ This was abondoned for a "better solution" last September. Was this referring to the changes in 4.4.0? Lastly has anyone who was running 4.3.9 upgrade their centos host to centos8 and then upgrade ovirt without any issues? I usually try and wait at least a couple of minor version changes before switching to a new major version. Thanks guys!

Ovirt vs lvm?
by csabany＠freemail.hu 26 Apr '20

26 Apr '20

Hi, Our production ovirt system looks like: standalone management server, vesion 4.3.9, 6 clusters, 28 nodes (v4.2, v4.3) , one storage domain, (FC SAN Storages), centos7 vm-s , and some windows vms. I have a returning problem. Sometime when i power off a vm and power on again , i get an error message our linux vm (when we use lvm of course): dracut: Read-only locking type set. Write locks are prohibited., dracut: Can't get lock for vg. I can repair only 70% of damaged vm. I tried to localize the problem, but a can`t. The error occured randomly every cluster, every storage on last 2 years. Has anyone ever encountered such a problem?

How to force removal of old host from Engine
by Shareef Jalloq 24 Apr '20

24 Apr '20

Hi, I seem to have got a stale host in my engine that I can't remove. I recently reinstalled oVirt Node on this host and while trying to refresh the host in the engine, have got it in some state where I can't do anything. The host is listed as Status=Unassigned. Under the Management pull down I only have Restart and Stop options, both of which error if selected. The Remove button is not available. How do I force a removal of this host from the view so I can reload it? Shareef.

Move Hosted Engine VM to a different storage domain
by Anton Louw 24 Apr '20

24 Apr '20

Hi All, I know this question has been asked before, by myself included. I was hoping that someone has run through the exercise of moving the hosted engine VM to a different storage domain. I have tried many routes, but the backup and restore does not work for me. Is there anybody that can perhaps give me some guidelines or a process I can follow? The reason I need to move the HE VM is because we are decommissioning the current storage array where the HE VM is located. Thank you very much Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

This ovirt-administrator group is only for accessing(authentication & sso) ovirt engine admin panel and, as far as I understand it, it does restrict access to particular engine's admin functions.

Batch delete Snapshots
by Christian Reiss 22 Apr '20

22 Apr '20

Hey folks, quick question: Can this be made batch-able? # gluster snapshot delete all System contains 1 snapshot(s). Do you still want to continue and delete them? (y/n) So for a script I could do a snapshot, copy the contents and auto-remove all snapshots after. I could go with snapshot list and act on those, but this seems like it should be in the code? -Chris. -- with kind regards, mit freundlichen Gruessen, Christian Reiss

With so much experience in IPTABLES - it's understandable, but keep in mind that in CentOS/RHEL 8 iptables command is just a translator to nftables - with limited capability and I don't think that it was a coincidence . With firewalld you can still achive 90-95% of what you could do in IPTABLES while the rules are quite clear even for a new admin. What I really like is that you can predefine the ports and protos for a specific service and easily deploy it via salt or ansible. Best Regards, Strahil Nikolov

Safely disable firewalld [Ovirt 4.3]
by francesco＠shellrent.com 22 Apr '20

22 Apr '20

Hi all, I was wondering if it's "safe" disabling entirely the firewalld service and manage the firewall only via iptables, on the host and on the hosted engine (a self-hosted engine). It would make a lot easier the managing the firewall rules for me because of many automatisms I created based on iptables. Did anyone manage to do this? Any contraindication for doing this or precaution that I have to take care of? Thanks for your time and help, Francesco

Re: oVirt and KeyCloak intergration

Ok so this is definitely looking better. I get an error, but at least now it is saying : “The user admin@openidchttp is not authorized to perform login” This is strange though, because admin in by default should be allowed access?

However, now I recall I made some changes compared to blog post example: 1) /etc/ovirt-engine/extensions.d/openid-http-mapping.properties I added escaping in regexp for '\' ... config.mapAuthRecord.regex.pattern = ^(?<user>.*?)((\\\\(?<at>@)(?<suffix>.*?)@.*)|(?<realm>@.*))$<file://(%3f%3cat%3e@)(%3f%3csuffix%3e.*%3f)@.*)(%3f%3crealm%3e@.*))$)$> ... 2) /etc/httpd/ovirt-openidc.conf Escaping for '"' in error document snippet ... <LocationMatch ^/ovirt-engine/sso/(interactive-login- negotiate|oauth/token-http-auth)|^/ovirt-engine/callback> <If "req('Authorization') !~ /^(Bearer|Basic)/i"> Require valid-user AuthType openid-connect ErrorDocument 401 "<html><meta http-equiv=\"refresh\" content=\"0; url=/ovirt-engine/sso/login-unauthorized\"/><body><a href=\"/ovirt-engine/sso/login-unauthorized\">Here</a></body></html>" </If> </LocationMatch> ... These two issues were most probably caused by the blog site rendering. You might want to check engine.log (or server.log not really sure which one was that) for aaa extension initialization logs. They should appear at the beginning just after restarting engine. Unfortunately, at the moment I do not have running keycloak setup (I used to have a local VM) but I will try to find some time to set it up again once I'm done with another work item that actually consumes almost entire disk space for my 2 machines) Please let me know if anything changes after applying these config changes. It this works for you then I will request the blog post to be updated. Do you mind if I keep(re-post) this discussion back to users@ovirt in case other might have similar issues with keycloak integration? A.

Hello oVirt Community / infrastructure team, we would like to get guidance on how to mirror the oVirt content publicly. We replicate content using our own networks so we'd only be pulling the content from the oVirt content server from one location in Chicago. Please advise. Thank you, Adrian

Hopefully, I would be able to help you with it. There is excellent blog post[1] available. You might also check keycloak+ldap post [2], however, when I was working on the integration I was not aware of if and did not test it. The error you mentioned does not really indicate what exactly is wrong but it might suggest that there is some sort of misconfiguration with apache (you need to install and configure mod_auth_openidc as described at [1]). At least that happened in my case. In case you have already gone through it you could probably check apache logs. Under [1] there is a python script that can be used to check api calls, please update username/password and test it against your environment. Would it be possible post relevant piece of apache logs together with engine.log ?

oVirt and KeyCloak intergration
by Anton Louw 21 Apr '20

21 Apr '20

Hi Everybody, Has anybody gone the route of using KeyCloak to login to oVirt? KeyCloak has been configured and the neccesary configs have also been done on the engine. It redirects perfectly from the oVirt Web Login page to KeyCloak, but after logging into KeyCloak, I get redirected back to the oVirt Web Login. When trying to login again, I get the below error: [cid:ea1b2738-7e36-4cdb-8650-191d6992853c] server_error: Missing parameter: 'params' I have checked all the logs, but nothing is telling me what exactly the issue is. If anybody has any idea, please let me know. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

Migrate engine to another storage domain without losing engine settings?
by Simon Nylund 21 Apr '20

21 Apr '20

Have been trying to figure out a simple way of migrating our hosted-engine to another storage domain, while keeping the data on the same domain. Is there any safe way of doing this? Fortunately I've only tested this in a dev environment, where I ended up with not being to able to restore the backup I did. The only way I got it to work was to deploy a fresh engine attached to the new storage domain, and then import the data storage domain containing the vms. The problem with that is that I lose all the settings I had in my hosted engine, and the hosts.

spice options hook
by ozmen62＠hotmail.com 21 Apr '20

21 Apr '20

Hi, We're using oVirt 4.3 and want to use spice streaming to better user experience, for example youtube etc. I've tried to use before_vm_start script, but lots of problems came out. 1 - on default environmet, hook script returns of no such file or directory, because python3 does not exist on the system if i install python3, vdsm stops working if change interpreter in the script, vdms retuns rc=0 error code hook=114 and it does not appear on the vm custom properties So, could you help me to run this hook properly we've tested https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/spiceoptions Master and 4.3 branch returns same error code and nothing appeared on the "custom properties" is there anyone who is use it successfully 2 - for this experince is GPU neccessery (not vGPU) , our server has standard 8mb onboard gpu thanks

Correct workflow for modifying engine vm.conf file
by Gianluca Cecchi 20 Apr '20

20 Apr '20

Hello, I would like to know a way to interact and modify in a "supported"/working way the vm.conf file on shared storage that contains details for the engine vm and I think is the base to dynamically generate the /var/run/ovirt-hosted-engine-ha/vm.conf In the past it was possible to temporarily modify the file under /var/run (or copy to another location) and start engine with it, but now it seems it doesn't work and that the file is continuously updated/refreshed Eg on engine storage domain on a lab with oVirt 4.4. beta4 I have the tar file [root@novirt2 ~]# tar tvf /rhev/data-center/mnt/glusterSD/novirt2st.storage.local\:_engine/7c9397f5-859b-4fba-bcc5-4ecbd454a189/images/530490b0-935e-46a8-84f6-6cd6618c6f0d/2e0f414c-2589-4545-a0a4-3bfed24ef3fc -rw-r--r-- root/root 181 2020-04-19 15:04 broker.conf -rw-r--r-- root/root 2777 2020-04-19 15:04 fhanswers.conf -rw-r--r-- root/root 1076 2020-04-19 15:04 hosted-engine.conf -rw-r--r-- root/root 6 2020-04-19 15:04 version -rw-r--r-- root/root 1359 2020-04-19 15:04 vm.conf [root@novirt2 ~]# And its vm.conf has: cpuType=Cascadelake-Server,+md-clear,+mds-no,-hle,-rtm,+tsx-ctrl,+arch-capabilities I would like to modify it and remove the "+tsx-ctrl" flag. Is there anything in the database that generates modification in the file on shared storage and then on the directory under /var/run? Or how is all the workflow managed to generate at the end the xml file to use to start the engine vm? What is that initially determines how to populate the cpuType in vm.conf at all? Thanks, Gianluca

Hello All, did anyone observe the following behaviour: 1. Create a new disk from the VM -> disks UI tab 2. Disk creation failes , but stays in locked state 3. Gluster storage has no directory with that uuid 4. /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh doesn't find anything: [root@engine ~]# /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -q -t all Locked VMs Locked templates Locked disks Locked snapshots Illegal images Should I just delete the entry from the DB or I have another option ?

Enabling VT-d causes hard lockup
by Shareef Jalloq 20 Apr '20

20 Apr '20

Hi, I've been trying to get an old machine setup for PCIe passthrough but am seeing kernel hangs when booting into oVirt. This is a Supermicro X10DAi with dual E5-2695 V4's I think. I had VT-d enabled and added SR-IOV. Don't think there's anything else I need to enable in the BIOS is there? I just updated to the latest version for this board too. It always seems to be CPU#18 too : https://photos.app.goo.gl/HG7NcyWwfuq646HeA Shareef.

Re: VM's in status unknown
by Arik Hadas 19 Apr '20

19 Apr '20

I would start by querying the database with: select vm_name, status, run_on_vds from vms where vm_name in ('<name of vm1>', '<name of vm2>'); Their status should be '7' in that case. The more interesting part though is their 'run_on_vds' field - If it's non-empty and points to the host the VMs ran on, it probably means there's an issue in the communication between the engine and that host, so restarting the engine/vdsm can solve it. Otherwise, it would require a deeper look at the log to see why the engine lost track of the host they run on.

VM's in status unknown
by kim.kargaard＠noroff.no 17 Apr '20

17 Apr '20

Hi, We have a few Windows 10 VM's running on our ovirt 4.3, where when you shutdown the VM from within Windows, that VM does not shut down but gets a status of unknown in ovirt and one cannot do anything to the machines within the web gui. This seems to specfically be related to that Windows 10 template that we have created. Any ideas? Also, any ideas on how one can shut these machines down? Thanks Kim

Hey folks, Some weeks ago I installed oVirt on top of a fresh CentOS 7 installation. I went ahead according to the official setup, which is basically to actiate a repo and then install via engine. When I try to run "yum update" on the hosts, I get a dependency error: --> Finished Dependency Resolution Error: Package: libvirt-daemon-driver-storage-4.5.0-23.el7_7.6.x86_64 (updates) Requires: libvirt-daemon-driver-storage-gluster = 4.5.0-23.el7_7.6 Installed: libvirt-daemon-driver-storage-gluster-4.5.0-23.el7_7.5.x86_64 (@updates) libvirt-daemon-driver-storage-gluster = 4.5.0-23.el7_7.5 Error: Package: vdsm-gluster-4.30.40-1.el7.x86_64 (@ovirt-4.3) Requires: vdsm = 4.30.40-1.el7 Removing: vdsm-4.30.40-1.el7.x86_64 (@ovirt-4.3) vdsm = 4.30.40-1.el7 Updated By: vdsm-4.30.43-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.43-1.el7 Available: vdsm-4.30.8-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.8-1.el7 Available: vdsm-4.30.9-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.9-1.el7 Available: vdsm-4.30.11-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.11-1.el7 Available: vdsm-4.30.12-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.12-1.el7 Available: vdsm-4.30.13-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.13-1.el7 Available: vdsm-4.30.14-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.14-1.el7 Available: vdsm-4.30.15-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.15-1.el7 Available: vdsm-4.30.16-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.16-1.el7 Available: vdsm-4.30.17-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.17-1.el7 Available: vdsm-4.30.18-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.18-1.el7 Available: vdsm-4.30.19-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.19-1.el7 Available: vdsm-4.30.20-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.20-1.el7 Available: vdsm-4.30.21-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.21-1.el7 Available: vdsm-4.30.22-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.22-1.el7 Available: vdsm-4.30.23-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.23-1.el7 Available: vdsm-4.30.24-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.24-1.el7 Available: vdsm-4.30.25-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.25-1.el7 Available: vdsm-4.30.26-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.26-1.el7 Available: vdsm-4.30.28-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.28-1.el7 Available: vdsm-4.30.29-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.29-1.el7 Available: vdsm-4.30.30-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.30-1.el7 Available: vdsm-4.30.31-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.31-1.el7 Available: vdsm-4.30.32-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.32-1.el7 Available: vdsm-4.30.33-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.33-1.el7 Available: vdsm-4.30.34-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.34-1.el7 Available: vdsm-4.30.35-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.35-1.el7 Available: vdsm-4.30.36-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.36-1.el7 Available: vdsm-4.30.37-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.37-1.el7 Available: vdsm-4.30.38-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.38-1.el7 Available: vdsm-4.30.39-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.39-1.el7 Available: vdsm-4.30.42-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.42-1.el7 Error: Package: libvirt-daemon-driver-storage-gluster-4.5.0-23.el7_7.5.x86_64 (@updates) Requires: libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.5 Removing: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.5.x86_64 (@updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.5 Updated By: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.6.x86_64 (updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.6 Available: libvirt-daemon-driver-storage-core-4.5.0-23.el7.x86_64 (base) libvirt-daemon-driver-storage-core = 4.5.0-23.el7 Available: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.1.x86_64 (updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.1 Available: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.3.x86_64 (updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.3 What did I miss here?

Multitenant scenario in oVirt
by Michal Gutowski 17 Apr '20

17 Apr '20

Hi oVirt community, I'm playing with a multitenant use-case in oVirt 3.4.6... My setup is as follows: - I have two working Data Centers (DC1 and DC2) - I created two additional users DC1-admin and DC2-admin - In DC1 permission settings I've added DC1-admin as a user with a builtin DataCenterAdmin Role. - In DC2 permission settings I've added DC2-admin as a user with a builtin DataCenterAdmin Role. Now in terms of permissions all is good: DC1-admin is not able to modify anything in DC2 and DC2-admin is not able to modify anything in DC1. However in both the Admin Portal and the VM Portal DC1-admin and DC2-admin can still see all other datacenter resources. My expectation was that if I login to the Admin Portal as e.g. DC2-admin I will only see DC2 datacenter in the GUI and nothing else. Same with VM Portal. I played with different user settings but I couldn't make it work... I think the problem is that whatever user you create it will always belong to the build-in "everyone" group and inherit permission to see everything in the portal. Is it possible to achieve a scenario where e.g. DC2-admin will login to the Admin Portal and only see resources that belong to DC2 and nothing else? Thanks, Michal

Sometimes paused due to unknown storage error on gluster
by Gianluca Cecchi 16 Apr '20

16 Apr '20

Hello, having deployed oVirt 4.3.9 single host HCI with Gluster, I see some times VM going into paused state for the error above and needing to manually run it (sometimes this resumal operation fails). Actually it only happened with empty disk (thin provisioned) and sudden high I/O during the initial phase of install of the OS; it didn't happened then during normal operaton (even with 600MB/s of throughput). I suspect something related to metadata extension not able to be in pair with the speed of the physical disk growing.... similar to what happens for block based storage domains where the LVM layer has to extend the logical volume representing the virtual disk My real world reproduction of the error is during install of OCP 4.3.8 master node, when Red Hat Cores OS boots from network and wipes the disk and I think then transfer an image, so doing high immediate I/O. The VM used as master node has been created with a 120Gb thin provisioned disk (virtio-scsi type) and starts with disk just initialized and empty, going through PXE install. I get this line inside events for the VM Mar 27, 2020, 12:35:23 AM VM master01 has been paused due to unknown storage error. Here logs around the time frame above: - engine.log https://drive.google.com/file/d/1zpNo5IgFVTAlKXHiAMTL-uvaoXSNMVRO/view?usp=… - vdsm.log https://drive.google.com/file/d/1v8kR0N6PdHBJ5hYzEYKl4-m7v1Lb_cYX/view?usp=… Any suggestions? The disk of the VM is on vmstore storage domain and its gluster volume settings are: [root@ovirt tmp]# gluster volume info vmstore Volume Name: vmstore Type: Distribute Volume ID: a6203d77-3b9d-49f9-94c5-9e30562959c4 Status: Started Snapshot Count: 0 Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: ovirtst.mydomain.storage:/gluster_bricks/vmstore/vmstore Options Reconfigured: performance.low-prio-threads: 32 storage.owner-gid: 36 performance.read-ahead: off user.cifs: off storage.owner-uid: 36 performance.io-cache: off performance.quick-read: off network.ping-timeout: 30 features.shard: on network.remote-dio: off cluster.eager-lock: enable performance.strict-o-direct: on transport.address-family: inet nfs.disable: on [root@ovirt tmp]# What about config above, related to eventual optimizations to be done based on having single host?

Hi, I'm trying to set up one of our nodes with PCI passthrough but there is a dead lnk in the documentation for the kernel boot parameter section of creating a new host. https://www.ovirt.org/documentation/admin-guide/sect-Explanation_of_Setting… Anyone know where this went or can help me with the options?

How to load VMs after importing a domain
by Shareef Jalloq 16 Apr '20

16 Apr '20

I've followed the online instructions on importing a pre-configured domain into a new data centre but I can't see how to import the VMs. The documentation just says, "You can now import virtual machines and templates from the storage domain to the data center." with no other info. What do I need to do in order to get my VMs up and running? Cheers, Shareef.

Single SPM Host orphaned from ovirt-engine, cannot confirm host rebooted or maintenance host.
by Terry 16 Apr '20

16 Apr '20

We have number of clusters connected to ovirt-engine. Some of these are single host clusters (running ovirt-release43-4.3.5.2-1 on CentOS7) with local storage. Recently, ovirt-engine started reporting one of these hosts NonResponsive, VMs were still running on the host but ovirt seems unable to communicate with it, testing shows no issues connecting engine -> host:vdsm and likewise the host can communicate with the engine on port 80 and 443. The host in question cannot be managed via IPMI for power management but we are able to perform an SSH reboot via the engine interface. We opted to login to the running virtual machines, shut them down and issue the SSH reboot from the engine. The server changes to rebooting status for some time and then reports NonResponsive state. We are unable to maintenance the host or confirm host has been rebooted manually as we are presented with the following "Error while executing action: Cannot perform confirm 'Host has been rebooted'. Another power management action is already in progress." The VDSM logs on the host in question are continually showing: 2020-04-16 08:23:51,478+0000 INFO (vmrecovery) [vds] recovery: waiting for storage pool to go up (clientIF:711) 2020-04-16 08:23:52,332+0000 INFO (jsonrpc/7) [vdsm.api] FINISH getStoragePoolInfo error=Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',) from=::ffff:10.10.1.252,33680, task_id=420249a4-55c0-436d-92c7-ea1286a0e287 (api:52) 2020-04-16 08:23:52,332+0000 ERROR (jsonrpc/7) [storage.TaskManager.Task] (Task='420249a4-55c0-436d-92c7-ea1286a0e287') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "<string>", line 2, in getStoragePoolInfo File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 2550, in getStoragePoolInfo pool = self.getPool(spUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 351, in getPool raise se.StoragePoolUnknown(spUUID) StoragePoolUnknown: Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',) 2020-04-16 08:23:52,333+0000 INFO (jsonrpc/7) [storage.TaskManager.Task] (Task='420249a4-55c0-436d-92c7-ea1286a0e287') aborting: Task is aborted: "Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',)" - code 309 (task:1181) During this period, the following is observed in the engine logs: 2020-04-16 08:23:52,307Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM compute01.ovirt.local command SpmStatusVDS failed: Message timeout which can be caused by communication issues 2020-04-16 08:23:52,307Z ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.SpmStatusVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] Command 'SpmStatusVDSCommand(HostName = compute01.ovirt.local, SpmStatusVDSCommandParameters:{hostId='67dc53da-d5ee-461e-87de-2ca6dd78637f', storagePoolId='6baea5dc-b049-47c2-a94f-5229c37c62d0'})' execution failed: VDSGenericException: VDSNetworkException: Message timeout which can be caused by communication issues 2020-04-16 08:23:52,346Z ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.GetStoragePoolInfoVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] Failed in 'GetStoragePoolInfoVDS' method 2020-04-16 08:23:52,355Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] EVENT_ID: IRS_BROKER_COMMAND_FAILURE(10,803), VDSM command GetStoragePoolInfoVDS failed: Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',) 2020-04-16 08:23:52,356Z ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] IrsBroker::Failed::GetStoragePoolInfoVDS: IRSGenericException: IRSErrorException: Failed to GetStoragePoolInfoVDS, error = Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',), code = 309 The metadata file for the local storage domain looks fine?

Can't migrate over migration network
by briandumont＠gmail.com 15 Apr '20

15 Apr '20

Hello, I am trying to configure a dedicated migration network and am unable to get it to work. It is failing with a no route to host error in the cockpit logs, specifically a libvirtd error virNetSocketNewConnectTCP:591 : unable to connect to server at '192.168.1.50:49152': No route to host. Trying to migrate from Host 1 to Host 2. 192.168.1.50 is the ip address on the source host for the migration. If I try to migrate in the other direction I get the same error with tthat hosts migration network ip. My migration network is setup on a different VLAN than my ovirtmgmt network. Here is my configuration: - 2 Hosts - Host 1 - nic 1 - ovirtmgmt - 192.168.1.24/24 - VLAN 1 - nic 2 - migration network - 192.168.1.50/24 VLAN 25 - Host 2 - nic 1 - ovirtmgmnt - 192.168.1.24/24 - VLAN 1 - nic 2 - migration network - 192.168.1.51/24 - VLAN 25 Migration network is setup as follows: - Assign - Yes - Required - Yes - VM Network - No (tried it with VM Nework = Yes with same results) - Migration Network - Yes I think I've got something fundamentally wrong with my host networking but I can't figure it out. Appreciate the help.

NUMA Pinning bug with Hugepages?
by Alan G 15 Apr '20

15 Apr '20

Hi, I seem to have found an issue when trying to setup a high performance VM utilising hugepages and NUMA pinning. The VM is configured for 32GB RAM and uses hugepages of size 1G. The host has two NUMA nodes each having 64GB RAM (for 128GB total system RAM). No other VMs are running or otherwise pinned to the host. The VM is pinned to node 0. And the required hugepages are allocated with echo 32 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages I then attempt to start the VM and get a pop-up error saying "cannot accommodate memory of VM's pinned virtual NUMA nodes within host's physical NUMA nodes". However, if I remove the hugepages from node 0 echo 0 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages Start the VM and then immediately re-create the hugepqages then everything works as expected. It seems to me that oVirt is considering the hugepages as allocated memory even if they are not in use. Is this correct? Thanks, Alan

upgrade VM cluster compatibility version
by Bill James 15 Apr '20

15 Apr '20

I'm trying to upgrade my cluster to 4.3. Currently its running 4.2.8.2-1.el7. But the cluster compatibility version is 3.6. I try to change that and it says I need to edit the VM. https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks.h… says: *Important:* An error message may warn that some virtual machines and templates are incorrectly configured. To fix this error, edit each virtual machine manually. The *Edit Virtual Machine* window provides additional validations and warnings that show what to correct. Sometimes the issue is automatically corrected and the virtual machine’s configuration just needs to be saved again. After editing each virtual machine, you will be able to change the cluster compatibility version. I edit the VM and there are no errors or warnings. I see no way to change the cluster compatibility level on a VM. How do I change the Custom Compatibility Version?? -- This email, its contents and attachments contain information from J2 Global, Inc. and/or its affiliates which may be privileged, confidential or otherwise protected from disclosure.

Get OAuth token locally without password?
by Chris Adams 14 Apr '20

14 Apr '20

I'm working on a cron job to run on the engine to do some tasks via the API. Is there a way I can get an API OAuth token created without actually storing a password? For example, some script that can be run to directly create a session in the database and return the token. Obviously this _can_ be done, it's a matter of knowing the right bits to do (so basically wondering if that has already been written). I only have internal users, so no external authentication store available. -- Chris Adams <cma(a)cmadams.net>

Migrate engine to another storage domain?
by Simon Nylund 14 Apr '20

14 Apr '20

Is there a successful way of migrating an up and running engine to another storage domain? I've been reading through the archive and tested a few various ways without any success. The only way i found working without errors was deploying a new engine attached to the new storage domain, and import the old data domain for the vms, but then you lose all the settings for the previous engine (ofc). And have to redo all of that.

Total LUN Limitations
by Ryan Chewning 13 Apr '20

13 Apr '20

I'm hoping that someone might be able to clarify a limitation found in the RedHat documentation. The documentation indicates that there is a limitation of 300 LUNS per block based storage device. Does this include LUNs which are directly mapped to a VM? Or does this referrer to LUNs which serve as a storage repository for ISOs / VM disks?

Host fails to enter in maintenance due to migration failure
by Vinícius Ferrão 13 Apr '20

13 Apr '20

Hello, I’ve a host that’s preparing to maintenance for almost 20 hours now. There’s a huge VM on it, with 32 gigs of RAM and this VM is failing migration. So, there’s a way to cancel prepare for maintenance, so the host can stop trying this migration that’s end up failing? I can just shutdown the VM to do the maintenance on the host... Thanks,

Looking through the logs I saw references to the blocksize but since that is contained in the ansible scripts which get downloaded to the host I gave up finding the source versions to try to see it I could get it going beyond that failing step.

engine certificate problems in MacOS Catalina
by Jayme 13 Apr '20

13 Apr '20

I recently setup a new ovirt environment using latest 4.3.9 installer. I can't seem to get the novnc client to work for the life of me in safari or chrome on MacOS catalina. I have downloaded the CA from the login page and imported it into keychain and made sure it was fully trusted. In both system and login keychains. Looking at this: https://support.apple.com/en-us/HT210176 seems to suggest that the certificate may be invalid if the issue date is longer than 825 days. The certificate generated by ovirt installer seems to be valid for 5 years. I'm not sure if this is the issue or something else is wrong but if cert length is a problem is there a way for me to re-regenerate a new certificate with a shorter issue period?

One more time
by eevans＠digitaldatatechs.com 13 Apr '20

13 Apr '20

I have thought about the issue with Windows vm's reporting the timezone incorrectly. I reaqlized that just last month, before I created my vm's that the Daylight Savings Time took affect moving our time up 1 hour. SO, based on that, instead of setting my time zone to US Eastern (GMT -5), I set it to SA Western (GMT -4) and the nasty exclamation mark disappeared. This tells me that DST (Daylight Savings Time) is not an option or configurable in Ovirt. I think this should be an easy fix for those of use that are stuck with it. I don't think the rest of the world participates in DST but most of the United States does. It would be nice to have those zones added as a configurable option that would switch on the dates it is nationally indicated to change. I hope the developers read this. Thanks.

DR on hyperconverged deployment
by wodel youchi 13 Apr '20

13 Apr '20

Hi, Need to understand somethings about DR on oVirt-HI - What does mean : Scheduling regular backups using geo-replication (point 3.3.4 RHHI 1.7 Doc Maintaining RHHI) : - Does this mean creating a check-point? - If yes, does this mean that the geo-replication process will sync data up to that check-point and then stops the synchronization, then repeat the same cycle the day after? does this mean that the minimum RPO is one day? - I created a snapshot of a VM on the source Manager, I synced the volume then I executed a DR, The VM was started on the Target Manager but the VM didn't have its snapshot, any idea??? Regards, be safe.

multiple subnets on hosts for vm's
by eevans＠digitaldatatechs.com 12 Apr '20

12 Apr '20

This is not critical but some functionality I think should be in Ovirt and maybe I am going about it the wrong way. I have several subnets on my physical network. My engine host is separate from the clustered hosts that house the vm's. In order for the vm's on the other subnets (vlans) to get Internet access, I have to add the extra ip addrs on the ovirtmgmt network interface. I have read and tried every solution I could find trying to add teh subnets without using the extra ip addrs option but the machine either becomes isolated or will not start at all. Can someone tell me how to add the vlans so the engine host sees and utilizes them? The engine host can get to resources on the vlans because of the router config but will not let any subnet except ovirtmgmt outside the cluster. This is not critical but something I would like to get working for future deployments. Thank you for your help. Eric

Windows 10 Pro 64 (1909) crashes when migrating
by Maton, Brett 11 Apr '20

11 Apr '20

I recently added a Windows 10 Pro 64 bit (release 1909) VM, and I'm seeing a lot of failures when oVirt tries to move the VM to another host (triggered by load balancing), These errors are showing up in the UI event log Migration failed (VM: <vm label>, Source: <host 1>, Destination: <host 2>). Followed by: VM <host> is down with error. Exit message: Lost connection with qemu process. Google returned some references to 'options kvm ignore_msrs=1' which I've added to /etc/modprobe/d/kvm.conf and restarted the hosts but that doesn't appear to have made a difference. Is this a known issue with Windows 10 guests?

Firewall GARP not reachable to VM
by k.betsis＠gmail.com 10 Apr '20

10 Apr '20

Hi all Does anyone know how i can allow my Firewall VM cluster act as the default gateway to VMs within the same network? I've configured the GARP functionality on the OPNSENSE firewalls (PFSENSE fork). VMs within the same network can ping the firewall IP addresses successfully but not the GARP IP. The ovirt network has been configured with the MAC Address Anti-spoofing to false. One firewall has been configured with virtio network drivers and the with e1000 both exhibiting the same behavior. Currently all VMs have been configured with a default gateway the primary firewall. Network workarounds using BGP and attributes can work, but are way to complicate to streamline for all VMs when a simple VRRP can do the job. Any ideas what i am missing?

Ovirt and Dell Compellent in ISCSI
by dalmasso＠cines.fr 10 Apr '20

10 Apr '20

hi all, we use ovirt 4.3 on dell server r640 runing centos 7.7 and a storage bay Dell Compellent SCv3020 in ISCSI. We use two 10gb interfaces for iSCSI connection on each dell server. If we configure ISCSI connection directly from web IU, we can’t specify the two physical ethernet interface , and there are missing path . (only 4 path on 8) So, on the shell of hypervisor we use this commands for configure the connections : iscsiadm -m iface -I em1 --op=new # 1st ethernet interface iscsiadm -m iface -I p3p1 --op=new # 2d ethernet interface iscsiadm -m discovery -t sendtargets -p xx.xx.xx.xx iscsiadm -m node -o show iscsiadm -m node --login after this, on the web IU we can connect our LUN with all path. Also, I don’t understand how to configure multipath in the web UI . By defaut the configuration is in failover : multipath -ll : 36000d3100457e4000000000000000005 dm-3 COMPELNT,Compellent Vol size=500G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=1 status=active |- 23:0:0:1 sdb 8:16 active ready running |- 24:0:0:1 sdd 8:48 active ready running |- 25:0:0:1 sdc 8:32 active ready running |- 26:0:0:1 sde 8:64 active ready running |- 31:0:0:1 sdf 8:80 active ready running |- 32:0:0:1 sdg 8:96 active ready running |- 33:0:0:1 sdh 8:112 active ready running |- 34:0:0:1 sdi 8:128 active ready running I think round robind or another configuration will be more performent. So can we made this configuration , select physical interface and configure multipath in web UI ? for easyly maintenance and adding other server ? Thank you. Sylvain.

oVirt 4.4.0 Beta release refresh is now available for testing The oVirt Project is excited to announce the availability of the beta release of oVirt 4.4.0 refresh for testing, as of April 9th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. Important notes before you try it Please note this is a Beta release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not to be used in production. In particular, please note that upgrades from 4.3 and future upgrades from this beta to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Beta require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Known Issues - ovirt-imageio development is still in progress. In this beta you can’t upload images to data domains using the engine web application. You can still copy iso images into the deprecated ISO domain for installing VMs or upload and download to/from data domains is fully functional via the REST API and SDK. For uploading and downloading via the SDK, please see: - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_d… - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download… Both scripts are standalone command line tool, try --help for more info. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps 389-ds - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Beta? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support only for file based storage. iSCSI/FC storage do not support 4k disks yet. - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Gluster problems with new disk and device name change and overlap
by Gianluca Cecchi 07 Apr '20

07 Apr '20

Hi, I have configured a single host HCI environment through the GUI wizard in 4.3.9. Initial setup has thai layout of disks, as seen by the operating system: /dev/sda -> for ovirt-node-ng OS /dev/nvme0n1 --> for gluster, engine and data volumes /dev/nvme1n1 --> for gluster, vmstore volume So far so good and all is ok. I notice that, even with single path internal disks, at the end oVirt configures the gluster disks as multipath devices and LVM2 PV structure on top of the multipath devices. Is this for "code optimization" at low level or what is the rationale for that, as with Gluster normally you do use local disks and so single path? Multipath structure generated: [root@ovirt ~]# multipath -l nvme.8086-50484b53373530353031325233373541474e-494e54454c205353 dm-5 NVME,INTEL SSDPED1K375GA size=349G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 0:0:1:0 nvme0n1 259:0 active undef running eui.01000000010000005cd2e4b5e7db4d51 dm-6 NVME,INTEL SSDPEDKX040T7 size=932G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 2:0:1:0 nvme1n1 259:2 active undef running [root@ovirt ~]# Anyway, on top of the multipah devices On /dev/nvme0n1: gluster_vg_nvme0n1 volume group with gluster_lv_data and gluster_lv_engine On /dev/nvme1n1 gluster_vg_nvme1n1 volume group with gluster_lv_vmstore logical volume The problem arises when I add another nvme disk, that, occupying a PCI slot, it seems has always higher priority of the previous /dev/nvme1n1 disk and so takes its name.

Any suggestions? Thanks in advance, Gianluca

Auto-logout while editing
by Shareef Jalloq 07 Apr '20

07 Apr '20

There's a rather annoying bug in the Engine UI where you can be logged out while actively using the system. I've been logged out twice now while editing the settings for a new VM. I'm screen grabbing and documenting as I go but I was just logged out while editing the System settings for a new VM. Shareef.

snapshot options on remote NFS storage
by Jayme 07 Apr '20

07 Apr '20

Was wondering if there are any guides or if anyone could share their storage configuration details for NFS. If using LVM is it safe to snapshot volumes with running VM images for backup purposes?

Hi Anton, Sure thing. During the creation of the NFS storage, you should specify an export path. SSHing that export path will expose you to the storage domain's content.

ISO and Export domains deprecated
by Colin Coe 07 Apr '20

07 Apr '20

Hi all I'm trying to understand how ISO and Export domains going away is going to affect us. We have four RHV instances: - Prod DC1 (RHV4.1) - Prod DC2 (RHV4.1) - DEV (RHV4.3) - TEST (RHV4.3) Prod DC1, DEV and TEST all share export and ISO domains. Prod DC2 is remote and currently has its own ISO and Export domains. When ISO and Export domains go away, can I still share ISO domains between the RHV instances? Thanks

by Sandro Bonazzola 07 Apr '20

07 Apr '20

oVirt 4.4.0 Beta release refresh is now available for testing The oVirt Project is excited to announce the availability of the beta release of oVirt 4.4.0 refresh for testing, as of April 3rd, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. Important notes before you try it Please note this is a Beta release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. In particular, please note that upgrades from 4.3 and future upgrades from this beta to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Beta require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Known Issues - ovirt-imageio development is still in progress. In this beta you can’t upload images to data domains using the engine web application. You can still copy iso images into the deprecated ISO domain for installing VMs or upload and download to/from data domains is fully functional via the REST API and SDK. For uploading and downloading via the SDK, please see: - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_d… - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download… Both scripts are standalone command line tools, try --help for more info. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps 389-ds - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Beta? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support only for file based storage. iSCSI/FC storage do not support 4k disks yet. - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Add gluster storage domain incomplete documentation
by Gianluca Cecchi 07 Apr '20

07 Apr '20

Hello, I think both at oVirt and Red Hat official docs the steps regarding adding a new Gluster storage domain on an existing installation is quite confusing and misaligned. Below I explain my reasons for both. In the mean time, suppose I have a single host HCI with self hosted engine (but it could be useful to have hints for multi-hosts too) and the 3 storage domains configured during install (engine and data on a disk and vmstore on another disk). The system initially had 3 disks, the first used for the ovirt-node-ng system, the second for engine and data, the third for vmstore initial gluster storage domains Now I go and add a fourth disk, say 4Tb in size. I would like to create a new Gluster storage domain on it What are the suggested steps? BTW: after booting, the new disk has been automatically included in multipath eui.01000000010000005cd2e4b5e7db4d51 dm-6 NVME,INTEL SSDPEDKX040T7 size=3.6T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 1:0:1:0 nvme1n1 259:1 active undef running Coming back to the docs - oVirt documentation I base my considerations on page https://www.ovirt.org/documentation/admin-guide/chap-Working_with_Gluster_S… 1) the picture in that page is still based on 3.6 GUI, so the initial approach tends to make me feel the page could be not up to date 2) I would put the section "Creating a Storage Volume" before "Attaching a Gluster Storage Volume as a Storage Domain" and not the opposite as it is now 3) In "Creating a Storage Volume" there is the note that " You must create brick directories or mountpoints before you can add them to volumes. " This sentence in my opinion is not so clear (see also details at the end)... what is a user expected to have done on hypervisors? Creation of directories or file systems (and what type: prefered xfs or ext4?). Perhaps an example of commands would be useful. 4) in the workflow of creating volume, item 7: Click the Add Bricks button to select bricks to add to the volume. Bricks must be created externally on the Gluster Storage nodes. I would expect an indication of commands to be run instead... This implies knowledge of Gluster that the GUI functionality is aimed to hide... but so, not completely... I can see in my existing bricks, going to their advanced details: " xfs rw,seclabel,noatime,nodiratime,attr2,inode64,logbsize=128k,sunit=256,swidth=512,noquota " There is also the fstab portion of creating bricks... 5) In the workflow of creating volume, item 9: It is not clear the default "*" value for access if is the recommended one or not. I presume not - RHV documentation https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/ht… 4.3 Administrator Guide downloaded today Chapter 8, section 8.6 PREPARING AND ADDING RED HAT GLUSTER STORAGE There is reference to Red Hat Gluster Storage, version 3.4. I think it should be 3.5 instead? Because at the same time in 3.4 there is reference to RHV 4.1, not 4.3. While in "Configuring Red Hat Virtualization with Red Hat Gluster Storage" version 3.5 there is correct reference to RHV 4.3 Anyway this mix of product documentation is not optimal in my opinion. I would directly include inside RHV docs the Gluster part related to it, without jumping between the two comlete, with the risk of misalignment in time. Also, in Gluster Storage guide referred, there is the part related to volumes but not to bricks.... Possibly the correct reference for the brick part, that is the one missing in webadmin GUI, could be this: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/h… and/or this https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/h… ? Thanks for reading and hoping to get commands' workflow to configure this new disk for a new gluster storage domain. It seems inside the guides is oversimplified the process of creating bricks, that in the documentation seem actually to be xfs filesystems mounted over thin pool based logical volumes residing on top of volume groups with particular alignment settings specified during their creation....

Engine/host communication maybe broken
by Sven Achtelik 06 Apr '20

06 Apr '20

Hi All, I'm currently facing a situation which I don't know how to resolve and I don't know how that happened. The hosted engine HA part is working fine and the vm starts. It's accessible via the gui and that's it. It's showing some hosts online and some offline. It looks like it's not communication with the nodes anymore to get the latest status or to start task. Is there a cache or something that can be cleared on the engine vm to force a connection the the nodes ? Or is there a way to analyze if communication is really broken ? Any ideas how to start from here ? Thank you, Sven

"Actual timezone differs [...]" after using the new virtio-win guest tools
by Tobias Scheinert 06 Apr '20

06 Apr '20

Hi, we are currently preparing our Windows software packages for update oVirt from version 4.3 to version 4.4. One of the novelties[1] of version 4.4 is the change from the ovirt-guest-tools to the virtio-win guest tools. We are currently running version 4.3.9.4-1.el7 in our oVirt cluster. When we are installing the new virtio-win guest tools we get the tooltip message: "Actual timezone in the guest differs from the configuration". The guest agents of the two guest tools are completely different, the ovirt-guest-agent is written in Python, the qemu-guest-agent is written in C. So my guess was, that there would different result send to the ovirt-engine. As I looked into the sources of ovirt-engine, especially into the timezone Java stuff, I did not found any changes in the last few months. So is this bug fixed, with the new ovirt version 4.4, or is this aspect new? P.S. The os in the vm was Windows 10 version 1909 [1] <https://ovirt.org/release/4.4.0/> Best Regards Tobias Scheinert

Windows Guest Agent Issues Since 4.3
by Alex McWhirter 06 Apr '20

06 Apr '20

Upgraded a installation to 4.3, and update the guest agent on all VM's, now all of my Windows VM's have a exclamation point telling me to install the latest guest agent. Some parts of the guest agent still seem to work, the IP addresses are still showing in the portal, but not FQDN and for some machine the shutdown button no longer functions correctly. I also tried to a fresh 4.3 install on a test cluster, and at first it worked great. But after a few days all of the windows vm's on that setup are showing the same behavior. Linux guests are fine on both systems. Not really sure where to start looking.

oVirt 4.4.0 Beta release is now available for testing The oVirt Project is excited to announce the availability of the beta release of oVirt 4.4.0 for testing, as of March 27th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. Important notes before you try it Please note this is a Beta release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not to be used in production. In particular, please note that upgrades from 4.3 and future upgrades from this beta to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Beta require content that will be available in CentOS Linux 8.2 which are currently included in Red Hat Enterprise Linux 8.2 beta. If you want to have a better experience you can test oVirt 4.4.0 Beta on Red Hat Enterprise Linux 8.2 beta. Known Issues - ovirt-imageio development is still in progress. In this beta you can’t upload images to data domains. You can still copy iso images into the deprecated ISO domain for installing VMs. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps 389-ds - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Beta? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ <http://manageiq.org/>. In such a case, please be sure to take the qc2 image and not the ova image. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG is already available for CentOS Linux 8 Additional Resources: * Read more about the oVirt 4.4.0 release highlights: http://www.ovirt.org/release/4.4.0/ * Get more oVirt project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] http://www.ovirt.org/release/4.4.0/ [2] http://resources.ovirt.org/pub/ovirt-4.4-pre/iso/ -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>* <https://www.redhat.com/en/summit?sc_cid=7013a000002D2QxAAK>* *Red Hat respects your work life balance.

Re: Multiple NICs on hosted engine, oVirt 4.3
by Jiří Sléžka 06 Apr '20

Hello Paul, thanks for reply and for pointing me to RHV documentation. Shame on me, I forogot it exists and is well maintained and super relevant for oVirt. But in this case I am a bit lost. I can't find something relevant to my effort to modify HE vm's config to add the second NIC to it. Or do you mean I should change the location of vm.conf from /var/run location to something persistent and then modify this vm.conf as mentioned in that old post? For example, now I got this output for conf key [root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_shared conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_shared [root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_local conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_local Is it valid to change it to (for example) /etc/ovirt-hosted-engine/vm.conf and modify that file there? Is it safe for further updates, maintenance, etc.? Maybe the second question - which process creates vm.conf in /var/run path?

Re: oVirt Storage quota problems

Dear oVirt, Is there anyone willing and able to assist me in troubleshooting what seems to be multiple issues regarding quotas: 1. UI Exception each time I add Consumer to Quota. 2. User getting warning of not being authorized to ‘ConsumeQuota’ in order to AddVM or AddVMFromTemplate, even though User is in Consumers list. 3. Fishy quota usage percentage. I see this strange behavior on all my platforms, so it’s starting to look as a bug to me. Happy to provide any relevant logs or do tests needed. Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic ActiveVideo From: "Staniforth, Paul" <P.Staniforth(a)leedsbeckett.ac.uk> Date: Friday, 13 March 2020 at 18:19 To: "Vrgotic, Marko" <M.Vrgotic(a)activevideo.com>, "users(a)ovirt.org" <users(a)ovirt.org> Cc: Darko Stojchev <D.Stojchev(a)activevideo.com> Subject: Re: oVirt Storage quota problems Sorry haven't used quota in a while, one thought is there a template quota getting used?

Defining quota for storage, with threshold and grace b. Setting quota mode to enforced in datacenter c. Added Users as consumers of the Quota d. Updated quota from Default to qstorage for Templates and related images e. Updated quota from Default to qstorage from all existing VMs and the related Disks Problem: * the percentage of the Storage Consumption is jumping up and down, between 3% and 97%, and at certain point goes back to Unlimited * when checking under Storage tab inside quota name, the value “Used MB out of Total MB” is correct, however, when attempting to exceed the threshold, I am not getting a warning, even though I am consumer of a quota Second issue: User is added to qstorage quota as consumer. Still, when he tries to launch the VMs, Waring is displayed: Cannot add VM. The user is not a consumer of the Quota assigned to the resource. Have I missed something – could it be a permission issue, not a consumer issue. All my users are utilizing Administration Portal with limited set of permissions. They all have same Role assigned, but only few of them are having the problem I described as Second problem.

power_saving schedule not powering off hosts
by Maton, Brett 05 Apr '20

05 Apr '20

I've got a cluster made up of five physical hosts, (Dells with idrac 7 management) Power management / fencing enabled on all hosts. I've enabled the power_saving scheduling policy on my cluster, it's migrated all the VM's to a couple of physical hosts so three are sitting idle with no VM's. Shouldn't the power_saving policy shut down the idle hosts?

Problem with connecting the Storage Domain (Host host2 cannot access the Storage Domain(s) <UNKNOWN>)
by Patrick Lomakin 05 Apr '20

05 Apr '20

Hello, everyone! I need specialist help, because I'm already desperate. My company has four hosts that are connected to the vault. Each host has its own IP to access the storage, which means host 1 has an ip 10.42.0.10 and 10.42.1.10 -> host 2 has an ip 10.42.0.20 and 10.42.0.20 respectively. Host 1 cannot ping the address 10.42.0.20. Hardware I tried to explain in more detail. Host 1 has ovirt node 4.3.9 installed and hosted-engine deployed. When trying to add host 2 to a cluster it is installed, but not activated. There is an error in ovirt manager - "Host host2 cannot access the Storage Domain(s) <UNKNOWN>" and host 2 goes to "Not operational" status. On host 2, it writes "connect to 10.42.1.10:3260 failed (No route to host)" in the logs and repeats indefinitely. I manually connected host 2 to the storage using iscsiadm to ip 10.42.0.20. But the error is not missing(. At the same time, when the host tries to activate it, I can run virtual machines on it until the host shows an error message. VMs that have been run on host 2 continue to run even when the host has "Not operational" status. I assume that when adding host 2 to a cluster, ovirt tries to connect it to the same repository host 1 is connected to from ip 10.42.1.10. There may be a way to get ovirt to connect to another ip address instead of the ip domain address for the first host. I'm attaching logs: ----> /var/log/ovirt-engine/engine.log 2020-03-31 09:13:03,866+03 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghan dling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-90) [7fa128f4] EVENT_ID: VDS_SET_NONOPERATIONAL_DOMAIN(522), Host host2.school34.local c annot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter.

Multiple NICs on hosted engine, oVirt 4.3
by Jiří Sléžka 05 Apr '20

05 Apr '20

Hello, I would like to add second NIC to hosted engine vm (I need access to isolated network with host's power management). I found this solution... https://lists.ovirt.org/pipermail/users/2014-November/062610.html ...which seems to work in oVirt 3.5 but in oVirt 4.3 there is no file like /etc/ovirt-hosted-engine/vm.conf anymore. In the file /etc/ovirt-hosted-engine/hosted-engine.conf is a line ... conf=/var/run/ovirt-hosted-engine-ha/vm.conf ... which points to this config but this is a running config... Is there a way to add a second NIC to hosted engin vm? Cheers, Jiri

Hello, I'm wondering why the cgroup for the VM is generated, because I thought VM and cgroup are not related. does qemu/KVM use (memory) cgroup to handle memory resources or something else?

manual migration
by eevans＠digitaldatatechs.com 04 Apr '20

04 Apr '20

FYI: My issue with the inability to migrate is solved. The issue was the ovirt-engine-ui-extensions-1.0.10-1.el7.noarch updated to 1.0.13 and it killed the ability to migrate. In order to downgrade I had to download the rpm, ovirt-engine-ui-extensions-1.0.10-1.el7.noarch.rpm and run a yum downgrade command “yum downgrade ovirt-engine-ui-extensions-1.0.10-1.el7.noarch.rpm”. It would not downgrade any other way. Once it downgraded, migration ability was back. Thanks all for the help and support.

New Issue - Ovirt Status shows '?' or Down for all elements
by Mark Steele 02 Apr '20

02 Apr '20

Yesterday we had a storage crash that caused our hosted engine to stop and not auto-restart. We manually restarted it and this morning, all elements are showing a status of either question mark '?' or a red down chevron. We are running version oVirt Engine Version: 3.5.0.1-1.el6. We are chasing it down and see this in the log: 2020-04-01 10:15:53,060 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-23) Failed to refresh VDS , vds = e98f8f1d-dd1d-47c4-b039-d6eaaf578317 : hv-06, VDS Network Error, continuing Any insight into what might be causing this or the fix would be appreciated. *** *Mark Steele*

Ok. Personally, I like having an ISO repository, but I like the fact that's it will be optional. Thanks.

Hosted Engine stalled and unable to restart
by Mark Steele 02 Apr '20

02 Apr '20

Hello, We are on an older version (3.x - cannot be specific as I cannot get my ovirt hosted engine up). We experienced a storage failure earlier this evening - the hosted engine was originally installed with this storage domain although we have moved all VM's and disks off of it. The storage was restored and all the VM's are now running, but the ovirt engine is not pinging and is unreachable. I have attempted to locate it on my HV's using 'virsh list --all' but only one of those is taking my credentials - all the others fail to authenticate. Is there a way to locate what the credentials are on each HV since the default is not working? Additionally, is there any other way to locate the hosted engine and restart it directly from a HV? Thank you for your time and consideration. *** *Mark Steele*
