Restart oVirt-Engine

How ,without reboot of hosting system, do I restart the oVirt engine? # I tried below but do not seem to effect the virtual machine [root@thor iso]# systemctl restart ov ovirt-ha-agent.service ovirt-imageio.service ovn-controller.service ovs-delete-transient-ports.service ovirt-ha-broker.service ovirt-vmconsole-host-sshd.service ovsdb-server.service ovs-vswitchd.service [root@thor iso]# # You cannot restart the VM " HostedEngine " as it responses: Error while executing action: HostedEngine: - Cannot restart VM. This VM is not managed by the engine. Reason is I had to do some work on a node. Reboot it.. it is back up.. network is all fine.. Cockpit working fine... and gluster fine.. But oVirt-Engine refuses to accept the node is up. -- p <jeremey.wise(a)gmail.com>enguinpages

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.

How to re-enroll (or renew) host certificates for a single-host hosted-engine deployment?
by Derek Atkins 28 Jun '24

28 Jun '24

Hi, I've got a single-host hosted-engine deployment that I originally installed with 4.0 and have upgraded over the years to 4.3.10. I and some of my users have upgraded remote-viewer and now I get an error when I try to view the console of my VMs: (remote-viewer:8252): Spice-WARNING **: 11:30:41.806: ../subprojects/spice-common/common/ssl_verify.c:477:openssl_verify: Error in server certificate verification: CA signature digest algorithm too weak (num=68:depth0:/O=<My Org Name>/CN=<Host's Name>) I am 99.99% sure this is because the old certs use SHA1. I reran engine-setup on the engine and it asked me if I wanted to renew the PKI, and I answered yes. This replaced many[1] of the certificates in /etc/pki/ovirt-engine/certs on the engine, but it did not update the Host's certificate. All the documentation I've seen says that to refresh this certificate I need to put the host into maintenance mode and then re-enroll.. However I cannot do that, because this is a single-host system so I cannot put the host in local mode -- there is no place to migrate the VMs (let alone the Engine VM). So.... Is there a command-line way to re-enroll manually and update the host certs? Or some other way to get all the leftover certs renewed? Thanks, -derek [1] Not only did it not update the Host's cert, it did not update any of the vmconsole-proxy certs, nor the certs in /etc/pki/ovirt-vmconsole/, and obviously nothing in /etc/pki/ on the host itself. -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

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

Deploy oVirt Engine fail behind proxy
by Matteo Bonardi 21 Mar '24

Hi, I am trying to deploy the ovirt engine following self-hosted engine installation procedure on documentation.

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?

VM HostedEngine is down with error
by souvaliotimaria＠mail.com 26 May '22

26 May '22

Hello everyone, I have a replica 2 + arbiter installation and this morning the Hosted Engine gave the following error on the UI and resumed on a different node (node3) than the one it was originally running(node1). (The original node has more memory than the one it ended up, but it had a better memory usage percentage at the time). Also, the only way I discovered the migration had happened and there was an Error in Events, was because I logged in the web interface of ovirt for a routine inspection. Βesides that, everything was working properly and still is. The error that popped is the following: VM HostedEngine is down with error. Exit message: internal error: qemu unexpectedly closed the monitor: 2020-09-01T06:49:20.749126Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2020-09-01T06:49:20.927274Z qemu-kvm: -device virtio-blk-pci,iothread=iothread1,scsi=off,bus=pci.0,addr=0x7,drive=drive-ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,id=ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,bootindex=1,write-cache=on: Failed to get "write" lock Is another process using the image?. Which from what I could gather concerns the following snippet from the HostedEngine.xml and it's the virtio disk of the Hosted Engine: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads' iothread='1'/> <source file='/var/run/vdsm/storage/80f6e393-9718-4738-a14a-64cf43c3d8c2/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7'> <seclabel model='dac' relabel='no'/> </source> <target dev='vda' bus='virtio'/> <serial>d5de54b6-9f8e-4fba-819b-ebf6780757d2</serial> <alias name='ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> I've tried looking into the logs and the sar command but I couldn't find anything to relate with the above errors and determining the reason for it to happen. Is this a Gluster or a QEMU problem? The Hosted Engine was manually migrated five days before on node1. Is there a standard practice I could follow to determine what happened and secure my system? Thank you very much for your time, Maria Souvalioti

OVS switch type for hosted-engine

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? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.

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.

Hello everyone. I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage. I'm using the oVirt 4.3.10 How do I reprovision the VM disk? Thank you all.

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?

oVirt 4.4.4 not dislaying Sign-on Screen
by louisb＠ameritech.net 07 Apr '21

07 Apr '21

I recently installed oVirt 4.4.4, everything appeared to run successfully, however, I’m unable to get the sign-on screen to display on my RHEL 8.3 machine. I did do an install using the remote database installation. I encountered no issue with the install, I can see the “engine” and “ovirt_engine_history” in PostgreSQL 13.3. The tables and table spaces have all been created as designed by the installation process. When I enter the URL that was displayed once the installation completed I get the following information displayed on the screen: Internal Error I’ve tried using the port 443 and port 80 URL and get the same results. The URL are as follows: http://WorkstationName:80/ovirt-engine https://WorkstationName:443/ovirt-engine For three days I’ve been trying to locate logs that will help me located and resolve the problem, but so far I’ve had no luck. Can anyone tell where I should start looking to resolve my issue? I’ve checked several system logs and logs for Apache with luck. What should I be looking for within the logs? What logs should I be looking at? I don’t believe my issue is with the back-end database, I thinks its something with Apache not being able to find the web pages to display. How can I start to investigate my problem an develop a solution? My Linux/RHEL 8.3 OS has all of the latest patches and fixes applied. Thanks

Problems after upgrade from 4.4.3 to 4.4.4
by tferic＠swissonline.ch 06 Apr '21

06 Apr '21

Hi I have problems after upgrading my 2-node cluster from 4.4.3 to 4.4.4. Initially, I performed the upgrade of the oVirt hosts using the oVirt GUI (I wasn't planning any changes). It appears that the upgrade broke the system. On host1, the ovirt-engine was configured to run on the oVirt host itself (not self-hosted engine). After the upgrade, the oVirt GUI didn't load in the Browser anymore. I tried to fix the issue by migrating to self-hosted engine, which did not work, so I ran engine restore and engine-setup in order to get back to the initial state. I am now able to login to the oVirt GUI again, but I am having the following problems: host1 is in status "Unassigned", and it has the SPM role. It cannot be set to maintenance mode, nor re-installed from GUI, but I am able to reboot the host from oVirt. All Storage Domains are inactive. (all NFS) In the /var/log/messages log, I can see the following message appearing frequently: "vdsm[5935]: ERROR ssl handshake: socket error, address: ::ffff:192.168.100.61" The cluster is down and no VM's can be run. I don't know how to fix either of the issues. Does anyone have an idea? I am appending a tar file containing log files to this email. http://gofile.me/5fp92/d7iGEqh3H <http://gofile.me/5fp92/d7iGEqh3H> Many thanks Toni

Locked disks
by Giulio Casella 01 Apr '21

01 Apr '21

Since yesterday I found a couple VMs with locked disk. I don't know the reason, I suspect some interaction made by our backup system (vprotect, snapshot based), despite it's working for more than a year. I'd give a chance to unlock_entity.sh script, but it reports: CAUTION, this operation may lead to data corruption and should be used with care. Please contact support prior to running this command Do you think I should trust? Is it safe? VMs are in production... My manager is 4.4.4.7-1.el8 (CentOS stream 8), hosts are oVirt Node 4.4.4 TIA, Giulio

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

Gluster volume engine stuck in healing with 1 unsynched entry & HostedEngine paused
by souvaliotimaria＠mail.com 11 Mar '21

11 Mar '21

Hello everyone, Any help would be greatly appreciated in the following problem. In my lab, the day before yesterday, we had power issues, with a UPS going off-line and following the power outage of the NFS/DNS server I have set up to serve ovirt with isos and as a DNS server (our other DNS servers are located as VMs within the oVirt environment). We found a broadcast storm on the switch (due to a faulty NIC on the aformentioned UPS) that the ovirt nodes are connected and later on had to re-establish several of the virtual connections as well. The above led to one of the hosts becoming NonResponsive, two machines becoming unresponsive and three VMs shuting down. The oVirt environment, version 4.3.5.2, is a replica 2 + arbiter 1 environment and runs GlusterFS with the recommended volumes of data, engine and vmstore. So far, the times there was some kind of a problem, usually oVirt was able to solve it by its own. This time, however, after we recovered from the above state, the volumes of data and vmstore successfully healing , the volume engine became stuck to the healing process (Up, unsynched entries, needs healing), and from the web GUI I see that the VM HostedEngine is paused due to a storage I/O error while the output of virsh list --all command shows that the HostedEngine is running.. How is that happening? I tried to manually trigger the healing process for the volume but nothing with gluster volume heal engine The command gluster volume heal engine info shows the following [root@ov-no3 ~]# gluster volume heal engine info Brick ov-no1.ariadne-t.local:/gluster_bricks/engine/engine Status: Connected Number of entries: 0 Brick ov-no2.ariadne-t.local:/gluster_bricks/engine/engine /80f6e393-9718-4738-a14a-64cf43c3d8c2/images/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7 Status: Connected Number of entries: 1 Brick ov-no3.ariadne-t.local:/gluster_bricks/engine/engine /80f6e393-9718-4738-a14a-64cf43c3d8c2/images/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7 Status: Connected Number of entries: 1 This morning I came upon this Reddit post https://www.reddit.com/r/gluster/comments/fl3yb7/entries_stuck_in_heal_pend… where it seems that after a graceful reboot one of the ovirt hosts, the gluster came back online after it completed the appropriate healing processes. The thing is from what I have read that when there are unsynched entries in the gluster a host cannot be put into maintenance mode so that it can be rebooted, correct? Should I try to restart the glusterd service. Could someone tell me what I should do? Thank you all for your time and help, Maria Souvalioti

Hello everyone, I operate several oVirt clusters including pre-productions using ovirt-node-ng images. For our traditional clusters we manage the incident in a unitary way with a dedicated rpm, however for ovirt-node-ng I am not yet up to date with critical package updates process. Do you have any advice or tips? Nice day, Renaud

Right Glusterfs Config on HA Server
by Marcel d'Heureuse 04 Mar '21

04 Mar '21

Hi Guys or Girls, I have a problem in a productive system. We use three Servers which have a Raid 5 with four Harddrives SATA 8 TB 7200 rpms. The Systems are interconnected for Glusterfs with 1 GB/s. The Network Load between all three servers are between 5 and 8 % of the network. The Glusterfs has a separate VLAN which complete isolated from other networks. Find attached a small drawing. On that server we rum as HA and there are 8 VMs installed. Most of the VMs working well but if there is high load on the system some of the VM can't write the Data in a "good" speed on the disks. The Glusterfs is configured as Replica on the Raid5 disk which is as Jbob in Glusterfs defined. If i take a look on the iostats i can see that the Harddisk have round 50 open connections some of the glusterfs and a lot of the vms. In side the VMs i can see long iowaiting times from 300 up to 600 ms. With is on case of a Posgresql database very long. Should we configure the Raid5 controller out that the controller only should 4 disks with 8 TB and Glusterfs should connect directly to the /dev/sd[b-e]? What do you think? Will SSD HDD will help on performance but the same config with Raid5 and Jbod could be the bigger problem. Thanks Marcel

How to enable nested virtualization
by miguel.garcia＠toshibagcs.com 02 Mar '21

02 Mar '21

Hi all, We are trying to run virtual box in a vm that is running over ovirt platform. I had followed the instruction to enable nested virtualization on host as described in this document https://ostechnix.com/how-to-enable-nested-virtualization-in-kvm-in-linux/ However I was not able to enable nested virtualization to the vm since nothing is listed from virsh console. Also tryed to edit vm configuration lookig up for "cpu mode" or "copy cpu configuration as host" Also from oVirt admin portal I had enabled host for nested virtualization through Compute > Host > selected Host > edit > Kernel Nested virtualization checked. But the host still returns: $ cat /sys/module/kvm_intel/parameters/nested N

2 Node oVirt Cluster
by justin.lamp96＠gmail.com 01 Mar '21

01 Mar '21

Hey there, I tried using oVirt for some time now and like to convert my main Proxmox Cluster (2 Nodes + RPI for Quorum) to oVirt. But I obvioulsy need three servers to do HA. Now I am asking myself: can't I just use the PI as an arbiter node for the Selfhosted-Engine on gluster? I tried running the playbook already, but it's always failing and even if the gluster deployment would go through, it would most likely fail aftwards, right? Before I waste too much energy and time into that, does anyone of you guys use a 2 node cluster? And no I can't add another node (energy + space + money)! Also I know with doing that I'm totally on my own etcetera Thanks!

oVirt4.1 add host error. can i upgrade from 4.1 to 4.4? without updating sequentially 4.1-4.2-4.3-4.4
by grig.4n＠gmail.com 01 Mar '21

01 Mar '21

HI! There is an oVirt 4.1 self-hosted engine cluster of two hosts and a storage connected via iscsi. When trying to add another host, it gives an error: "ERROR otopi.context context._executeMethod:151 Failed to execute stage 'Setup validation': Cannot locate vdsm package, possible cause is incorrect channels". Older hosts on Centos 7.5.1804, last on Centos 7.9.2009. Is it possible to go from 4.1 to 4.4 using the third host as the main one for the transfer?

Cant add vm network with vlan to bonded interface
by murat.celebi＠dbpro.com.tr 01 Mar '21

01 Mar '21

Hello, I am new to ovirt and try to migrate my companies vmware infra to ovirt. The Engine setup went fine without any problems. These are the steps which I am doing and having problems. 1. Prepare the KVM host by installing the RPM's. 2. Add the kvm host to the engine. Everything is working fine at this point. 3. I am creating a new Network for vm usage named VLAN10. And I am tagging the network with vlan id 10. 4. I am bonding two 25Gb/s interface's with balance-xor mode with the name bond1. 5. When I add the network VLAN10 to the bond1 interface I cant see the logical network assigned to the bond. After this step I am not able to delete the bond since I am getting errors when I try to delete the bond. Any help would be greatly appreciated. Thank you

oVirt Node install with Foreman VG issue
by simon＠justconnect.ie 28 Feb '21

28 Feb '21

Hi All, I have a server with a RAID1 disk for sda and RAID 5 disk for sdb. Following default install, prior to Cockpit Gluster and Engine wizards there is only a single Volume Group which doesn’t allow me to continue. If I manually configure the install and deselect sdb it gives other issues with multipath but at least I can resolve those. Is there a specific kickstart confuguration that should be used? Kind Regards Shimme

Re: oVirt Node install with Foreman VG issue
by Simon Scott 28 Feb '21

28 Feb '21

Thanks Strahil, Unfortunately changing the filter is done after the initial install. We manually partition sda so that sdb isn’t touched during install. The issues with multipath grabbing sdb are ongoing with a possible manual fix being tested now. Testing has paused at the moment as we have lost gluster on the arbiter node as per https://lists.ovirt.org/archives/list/users@ovirt.org/thread/U64MGWSUCFJRIV… which looks like a full oVirt rebuild again. Any help on that thread would be appreciated. Thanks again Shimme On 28 Feb 2021, at 08:35, Strahil Nikolov <hunter86_bg(a)yahoo.com> wrote: Most probably there is an LVM filter.

oVirt 4.2 cluster upgrade

I have a 3 node oVirt 4.2.1 cluster, i'm using a self-hosted engine architecture and storage-engine is on a glusterfs replica 3 of the cluster. The oldest CPU is SandyBridge family (E5-2609) and incidentally I have connectivity problems with IPMI NIC of one node, but Hosted Engine HA is enabled and working. Is it safe to upgrade to the last oVirt 4.4 without a down of vm running on the cluster? May I just click on the button Upgrade that appears on the host page?

[ANN] oVirt 4.4.5 Seventh Release Candidate is now available for testing
by Lev Veyde 25 Feb '21

25 Feb '21

oVirt 4.4.5 Seventh Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Seventh Release Candidate for testing, as of February 25th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Starting a defined VM on a different host
by lavi.buchnik＠exlibrisgroup.com 25 Feb '21

25 Feb '21

Hi, I might be missing something here, but I'm looking for the right API way to start a defined VM on a different host. The scenario is this: 1. VM is running under Cluster Affinity Host. and there is a need to cold migrate it to another host on that Affinity. 2. for that I will stop the VM. 3. And now I would like to start the VM on another host, I tried few ways like: vm_service.start( vm=types.Vm( host=types.Host( name='<host name>' ), ) ) But VM keep starting on the current host. Can you please show me the right way to do it. Thanks, Lavi

Q35: disk type view not consistent in edit vm and new disk pages
by Gianluca Cecchi 24 Feb '21

24 Feb '21

Hello, if I create a VM and select Q35 machine type, still the General --> create image option in edit phase doesn't show sata as an option. Even if I create the VM without disks and then go to edit General --> create, I only see IDE, VirtIO-SCSI and VirtIO. Instead if I click VM name, DIsks --> New, I can select VirtIO-SCSI, VirtIO and SATA After the first disk (SATA in my case) has been created, now if I go and edit VM --> General --> Instance Images + --> Create, I see consistent options. I think GUI experience could be improved. Also because I can reproduce this workflow converging to an error (even if IDE disks are not so common nowadays...): New VM In general I create an IDE disk In System I select in Advanced parameters, Custom Chipset/Firmware Type Q35 (EFI or BIOS based) go ahead At the final OK I get the error: Cannot add Virtual Disk: The disk interface is not supported by the VM OS: Other OS. The result is VM created but without the IDE disk as not supported in Q35 type. Tested in 4.4.4 Gianluca

Cannot add VM. Maximum number of threads per cpu exceeded
by Lavi.Buchnik＠exlibrisgroup.com 24 Feb '21

24 Feb '21

Hi, We have a strange thing, which not clear to us. When provisioning a new VM via REST API, if the number of vCPU for that VM is more than 16, I'm getting this error: Fault reason is "Operation Failed". Fault detail is "[Cannot add VM. Maximum number of threads per cpu exceeded]". HTTP response code is 409. Our version is: Version 4.3.6.6-1.0.9.el7 Note that manual provisioning from the UI do not produce any error when using vCPU > 16. It seems like the issue is related to this setting (from the engine): [root@olvmengine01 ~]# engine-config -g MaxNumOfThreadsPerCpu MaxNumOfThreadsPerCpu: 8 version: 4.1 MaxNumOfThreadsPerCpu: 8 version: 4.2 MaxNumOfThreadsPerCpu: 8 version: 4.3 [root@olvmengine01 ~]# But when trying to set it to another number, I'm always get this error, for example: [root@olvmengine01 ~]# engine-config -s MaxNumOfThreadsPerCpu=10 Please select a version: 1. 4.1 2. 4.2 3. 4.3 3 Cannot set value 10 to key MaxNumOfThreadsPerCpu. Questions: 1. Can you please explain why we getting this error: "Cannot add VM. Maximum number of threads per cpu exceeded"? 2. Is it related to engine-config -g MaxNumOfThreadsPerCpu? 3. Why it is working manually via the UI? 4. if its related to engine-config, why we can't set it to another number? Thanks in advance, Lavi

VM Portal. User can't access the details box
by Nicolás 24 Feb '21

24 Feb '21

Hi, We're running oVirt 4.1.8. We make an intense use of the VM Portal, as our students use it to access and handle their machines. We're currently having an issue with just one of our users. He claims that he created a VM, and when tried to edit its details (clicking on the pencil), a screen stating that the "VM Portal is experiencing some issues" is shown (screenshot added). I granted a UserRole permission on a user I handle, and I don't experience that problem, I can edit the VM with no issues. The user also states that this happens on any VM he creates. I see nothing relevant in the log regarding this issue. Please, any hint how to debug this? Thanks. Nicolás

oVirt Ansible cluster deployment
by Jeremey Wise 24 Feb '21

I am trying to eat own dog food. Infrastructure as code... So.. I have taken three physical servers. Setup all the base packages, set NICs, NTP, DNS, collected disk UUIDs etc.. The servers are prepped. And one server has cockpit and ovirt-engine installed... and service started. ############################# --- # This task takes nodes prepaired and deploys cockpit, ovirt deployment and scripts cluster initilization.

If so.. how do you collect feedback etc.. 2) I assume there is a template. Maybe it is published but I could not find it. That I replace (or match) variables of my site that fill in that file. 3) I installed galaxy oVirt.ovirt-ansible-roles but.. how do I know it is deployed on my bastion host? I poked around in the ansible folder.. not seeing anything. And I assume this only is of help POST the above seven steps being done. But maybe this has deployment components and I am missing documents. Thanks, -- p <jeremey.wise(a)gmail.com>enguinpages

Did you install ovirt-guest-tools on the VM from the iso available at your engine vm package? Did the related service start in WIndows 10 OS? You didn't reply why you are forced to use so an "old" oVirt version: it is not old in absolute, but oVirt is rapidly evolving and you should stay at maximum behind one version. So if the latest is 4.3, stay no behind 4.2. Now, with 4.4 out since many months, stay no behind 4.3 at least... This way you get more correct help because more guys are on latest versions, that got many enhancements and many bug fixes (eg with snapshot management, illegal disks state some time, and so on) Gianluca

Invalid status on Data Center Default. Setting status to Non Responsive.
by Jelte Veldstra | Order2Cash 23 Feb '21

23 Feb '21

All, We have built a new oVirt cluster from scratch. We used the 4.4.4 installer released in December 2020. When deploying the engine we had the wizard create a Gluster volume for the engine on three hosts. All went well and the cluster is starting to take shape. When starting the engine we do see the following error each time the engine is started in /var/log/ovirt-engine/engine.log: 2021-02-23 08:06:09,208+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-33) [4293beae] EVENT_ID: SYSTEM_CHANGE_STORAGE_POOL_STATUS_PROBLEMATIC(980), Invalid status on Data Center Default. Setting status to Non Responsive. Also when navigating in the engine web-ui to Compute -> Data Centers -> Default and check the events an event of id 980 is shown with the message: “Invalid status on Data Center Default. Setting status to Non Responsive.”. The date/time matches when the error is shown in the engine log. The datacenter overview does not show any warnings or errors and lists the Default datacenter as status Up. An interesting observation is that the cluster overview does have a status column on the far left, but the status is not mentioned. The field underneath the status heading is empty. Could that be the unknown status that the data center refers to? How could we investigate this further? The storage volumes do not show any issues and the cluster seems to function okay (it has not been used a lot yet as it has been built yesterday/today), but the error message does sound like something we need to get out of the way before we put the actual workload on it.

Hi Joseph, Somehow I missed your email. I am thinking in similar direction, but in all honesty, it’s takes bit of effort to accept that we need complete platform deployment from 4.3 to 4.4, considering EL 8 is required, to have this fixed. Anyway, let’s try re-deploying engine with current platform version in testing env, take our notes and share them. This is actually nice, team work. 😊 For now, in production, I am going to increase the RAM and CPU, and if reboot is required, just do it again. Too many CI/CD deployment failures, to leave the engine process fighting for resources. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

There are different parameters around memory - are you sure you change the correct one(s)? Also adding Arik. Arik - please see the history of this thread. It might be an issue in the engine, or in hosted-engine HA, or both - not sure. > But before I do that, we are currently on 4.3.8.2 version – is this by any change fixed by latest 4.3 version? No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it reproduces, file a bug and attach all relevant logs (including engine, vdsm, hosted-engine-ha).

Re: oVirt Engine increase RAM and CPU

Hi Marko, I have also had this problem on an oVirt 4.3 install - I could never fix it and have not tried to upgrade to 4.4 yet - my workaround for now (as you have deduced) is to just 'up' it while running so its hotswapped in - annoying, but I think the best way around this without upgrade would be to re-deploy the hosted engine defining the new resources using an engine-backup - but again this is just as scary as in-place upgrade lest you lock yourself out from your other running VMs in a production environment. I plan to do it - I just need some time to set it up in a lab so I know what to expect.

Initially, I made the change via Portal, updating defined memory of HE from 16384 to 32768. The change is instantly visible on VM when I execute free -m , but in the VM info it still says 16384. I waited almost 4hours and this value did not get updated. Tried shutdown, remove GM, allow the HA to start the VM, it booted with 16384 allocated. Than I did it again, and tried with Update OVF from storage domain where the HE disk is, same, no change. Tried, updating memory again, migrating to another HA host – Update OVF , same thing, after reboot, the memory is back to 16384. Can somebody give me an advice where to look further? Again, making the change in memory amount is instant on the VM, but after reboot, its back to 16384. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

oVirt Node install with Foreman VG issue
by simon＠justconnect.ie 22 Feb '21

22 Feb '21

Hi All, I have a server with a RAID1 disk for sda and RAID 5 disk for sdb. Following default install, prior to Cockpit Gluster and Engine wizards there is only a single Volume Group which doesn’t allow me to continue. If I manually configure the install and deselect sdb it gives other issues with multipath but at least I can resolve those. Is there a specific kickstart confuguration that should be used? Kind Regards Shimme

Mem guaranteed updates, CPU cores updates instantly and perist after reboot But defined memory is “stuck” on 16384 after reboot. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

Initially, I made the change via Portal, updating defined memory of HE from 16384 to 32768. The change is instantly visible on VM when I execute free -m , but in the VM info it still says 16384. I waited almost 4hours and this value did not get updated. Tried shutdown, remove GM, allow the HA to start the VM, it booted with 16384 allocated. Than I did it again, and tried with Update OVF from storage domain where the HE disk is, same, no change. Tried, updating memory again, migrating to another HA host – Update OVF , same thing, after reboot, the memory is back to 16384. Can somebody give me an advice where to look further? Again, making the change in memory amount is instant on the VM, but after reboot, its back to 16384. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

[ANN] oVirt 4.4.5 Sixth Release Candidate is now available for testing
by Lev Veyde 22 Feb '21

22 Feb '21

oVirt 4.4.5 Sixth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Sixth Release Candidate for testing, as of February 18th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production.

Please note that I do not have any experience with this whatsoever. Also for the further replies below. Just guessing. I suggest to try first on a test system if it's about a production/critical system. I guess that it will mark the VM as requiring a reboot for changes to take effect, and that they'll actually be applied only on hard-reboot (meaning, not just running 'reboot' from inside). So yes, I guess the process should be: 1. Edit as needed 2. Perhaps wait a bit or something like that to make sure changes reached OVF_STORE on the shared storage. No idea how. Perhaps we log enough about this to existing logs, or perhaps you can dump the conf to verify manually. 2. Set global maint, shutdown, clear global maint (and either immediately start the vm or let ha-agent do this for you). > > > > For the HEAP changes, I have been doing that lot on the Atlassian instances, just not sure how oVirt-engine is going to react and if there are any guidelines I should stick to in ovirt case. I have no idea other than the bugs I was personally involved with (which you can find in bugzilla). Perhaps RHV or oVirt docs have some guidelines, didn't check. If not, then I suppose the guidelines are "Use the defaults and follow recommendations", which mean: 1. Allocate 16GB RAM for the HE VM. Perhaps we even recommend more than that for larger setups, not sure. 2. engine-setup then sets both min and max to 4GB (=25% of RAM). If you do want to play with this, you should of course test thoroughly and carefully :-). Consider also other processes on the machine needing rather-large amounts of memory, including DWH and PostgreSQL (which we also automatically configure and which you can further refine if needed, and also set up to run on separate machines). > > I.e.

Hi Didi, Just to be sure, considering its an HA instance, I need to set to maintenance=global and execute these changes – CPU increase will most likely require reboot?

ovirt-vmconsole (serial console) dimensions and word wrap
by Kurt Myers 22 Feb '21

22 Feb '21

I frequently use the ovirt-vmconsole (serial console) to interact with my VMs. Is there a way to have ovirt-console recognize the terminal size automatically rather than defaulting to the standard 80 columns by 25 rows? If not, can the column/row size be adjusted globally (so the dimensions can be set once but persist for all console connected VMs)? Also, is there a way to enable word-wrap in the ovirt-vmconsole? Thanks! -Kurt-

4.3 -> 4.4 upgrade question
by KSNull Zero 21 Feb '21

21 Feb '21

Hello! We have only one 4.3 cluster and try to upgrade it to 4.4. I believe that engine-setup change the Cluster Setting "Default Network Provider" to "ovirt-provider-ovn" during upgrade procedure. So then we add freshly reinstalled RH8 host back to this cluster the oVirt tries to configure OVN on that host. But we don't want to use OVN. Is it safe to change this setting back to "No Default Provider" and continue hosts upgrade process ? Thank you.

Rebooting VM with mdev device reboots VM AND the host!
by paul.chapman＠farmgroup.tv 21 Feb '21

21 Feb '21

Hi I'm a new to Ovirt so please forgive any gaping hole in my knowledge. I have a self hosted engine set up with two hosts. Centos 8.3, Ovirt 4.4, (cluster set to 4.5 because it told me to). I have Nvidia Tesla T4 cards in both hosts with Nvidia driver 450.102. I have Win10 VMs on one host and the HE on another. The problem I have is that when you reboot the Win10 VM it also reboots the host it's sat on. I have 'intel_iommu=on' in my grub file and both hosts pass virt-host-validate. This set up was working fine on Centos 7 with Ovirt 4.3 so I'm at a bit of a loss to know what's going on. I'll post up the logs if anyone can let me know which ones they think would be relevant. Thanks in advance, Paul.

I have tried to upgrade from 4.3 to 4.4 in a self hosted environment and I now have multiple problems. One of which is that neither of my two hosts think they are running the hosted engine. What could cause this?

Changing the bridge for ovirt hosted engine
by Jordan Conway 21 Feb '21

21 Feb '21

Hello, I'd like to move my ovirt hosted engine deploy to a different cluster, but the problem that I'm faced with is that my hosted engine bridge runs on "ovirtmgmt" but the cluster I'd like to move it to the default vm network is "ovirtmgmt_vlan" Is there a process in which I could shutdown my hosted vm, edit it's network then bring it back up on the new cluster? I have already tried redeploying the new cluster with "deploy hosted engine" on it, but when I try to start the engine on a host in the new cluster it fails because it can't find the ovirtmgmt bridge. Thank you, Jordan Conway

oVirt Engine increase RAM and CPU

19 Feb '21

Hi oVirt, What is the cleanest way to increase the memory and cpu for SHE engine? We have the Engine running on top of three HA hosts, so I guess the specs need to be change on all three, while engine is down. Is it done by editing the VM libvirt conf file or some other way? Where do I allocate more RAM to JAVA for oVirt? We are currently running 4.3.8 version.

Self-hosted engine storage migration
by Domenico Princi 18 Feb '21

18 Feb '21

Hi to all, let me explain the scenario: In developer lab, I have a ovirt 4.1 environment with a single host and a self-hosted engine. The hosted engine runs on a nfs storage type. In this environment runs twelve VMs (thirteen if we include the self-hosted engine). So, now I have the urgency to do the following activities: 1) Migrate the hosted engine storage from nfs to fc (I have now an fc storage on this host). 2) Upgrade the ovirt to 4.3 release. So, I would like to have your help to understand how to implement the above two steps in this particular case ( one host and the self-hosted engine ). Regards

Small SAN suggestions?
by Chris Adams 18 Feb '21

18 Feb '21

I have an oVirt cluster with a significantly oversized SAN for storage (iSCSI, have 30TB storage but am only using about 2.5TB). I'm looking for a more appropriately-sized setup. Any suggestions? This is currently a Dell EqualLogic array - it doesn't look like they really even have a smallish VM-storage (at least that isn't VMware) product these days. Looking at our stats, we're doing more write than read ops (outside of when backups run), typically under 150 write ops per second. I'm not looking at replacing servers right now, so not looking at hyperconverged. Just interested in what hardware people are using these days for a setup this size. Thanks. -- Chris Adams <cma(a)cmadams.net>

Building new cluster today - OS recommendations
by Gervais de Montbrun 16 Feb '21

16 Feb '21

Hi All, I've been testing with a single server "cluster" running oVirt w/Gluster and am about to build my in house cluster using three Dell servers. I was planing on putting CentOS 8 on these servers and building oVirt on top. With the recent changes to CentOS changing to CentOS Stream, I have concerns. I'm tempted to build my cluster with CentOS 8 (as this is what I tested on) and assume that there will be some official word from oVirt as to how to proceed come end of year. Any suggestions from folks here? Any one know if there is anything out from oVirt crew already around this? Cheers, Gervais

Testing PXE uefi boot in oVirt
by Gianluca Cecchi 16 Feb '21

16 Feb '21

Hello, I'm testing a configuration with a CentOS 8.3 VM as a PXE server for UEFI boot. Its chipset/fw type is "I440FX Chipset with BIOS", I don't think it is important. And I have another (tobe, configured in hw as rhel 8.0) CentOS 8 VM configured now as "Q35 Chipset with UEFI" as a client. I already removed filters from vnics of both It seems that the client successfully downloads the BOOTX64.EFI but then fails fetching the netboot image with the message: Fetching Netboot Image Unable to fetch TFTP image: TFTP Error under tftp root dir I created grub.cfg this way set timeout=60 menuentry 'CentOS 8.3' { linuxefi images/c83/vmlinuz ip=dhcp inst.repo=http://172.20.0.1/c83/ initrdefi images/c83/initrd.img } and also a link to it with the mac address of the client in the form grub.cfg-00:1a:4a:19:01:54 -> grub.cfg documentation for uefi pxe server config is not quite clear on where to put it and naming Any good docs? Also the latest rh el 8.3 advanced installation guide is not so clear... See here for a screenshot: https://drive.google.com/file/d/1YJwgmg-0vTcXYWHbgCf81m8SLsN7Rwjf/view?usp=… For instance, is it expected that I can test this functionality at all using oVirt VMs? So the UEFI implementation for PXE boot? At the moment I'm using virtio as the vnic type for both the server and the client. Do I have to change them to something different (eg e1000)? Thanks in advance for any input. Gianluca

[ANN] oVirt 4.4.5 Fifth Release Candidate is now available for testing
by Lev Veyde 16 Feb '21

16 Feb '21

oVirt 4.4.5 Fifth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Fifth Release Candidate for testing, as of February 11th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Re: Ovirt - affinity labels names and virtual machines

Hi, I suggest sending questions to ovirt-users so others could find answers as well as to allow others who might know better chime in as well As to your question, something like this works for me: vms_service = connection.system_service().vms_service() vm_service = vms_service.vm_service('vm-id') affinity_labels = vm_service.affinity_labels_service().list() for affinity_label in affinity_labels: hosts = connection.follow_link(affinity_label.hosts) for host in hosts: print(connection.follow_link(host).name) (I am not sure where exactly the problem is in your code) On Mon, Feb 15, 2021 at 2:32 PM Lavi Bochnik <lavi.bochnik(a)gmail.com> wrote: > > Hello Benny, > > Not sure if I can email you directly, but you helped me once. > I have some VM's which are labeled with specific affinity. > Via API I would like to get a VM affinity label, in order to later get the hosts defined under that affinity. > I tried many ways as: > vm = vms_service.list(search='<vm_name>')[0] > print(vm.affinity_labels) > > or: > for affinity_label in affinity_labels: > print("%s:" % affinity_label.name) > for vm_link in connection.follow_link(affinity_label.vms): > vm = connection.follow_link(vm_link) > print(" - %s" % vm.name) > > Getting an href error: Error: The URL '/ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db/vms' isn't compatible with the base URL of the connection > > Href's are looking fine, as: > In [77]: for x in affinity_labels_service.list(): > ...: print(x.href) > > /ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db > /ovirt-engine/api/affinitylabels/862df742-fdc4-4eb0-933c-027729e2187d > /ovirt-engine/api/affinitylabels/686d96a6-0c9c-4fb7-b453-a79cbd48790b > /ovirt-engine/api/affinitylabels/6d42df24-c4b1-45e7-8029-0ce26b8ed73d > > Or this: > > 1 for affinity_label in affinity_labels: > ----> 2 for h in connection.follow_link(affinity_label.hosts): > 3 print(h) > 4 > 5 > > /usr/local/lib64/python3.6/site-packages/ovirtsdk4/__init__.py in follow_link(self, obj) > 782 raise Error( > 783 "The URL '%s' isn't compatible with the base URL of the " > --> 784 "connection" % href > 785 ) > 786 > > Error: The URL '/ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db/hosts' isn't compatible with the base URL of the connection > > Not clear what is the right way to get a VM affinity hosts list. > > Thanks, > Lavi

Hello guys, I found a problem when importing VMs from SDs and I filed https://bugzilla.redhat.com/show_bug.cgi?id=1927199 Is there any possible workaround to be able to import them? Everything I tried so far failed miserably... Thanks! -- Miguel Martín Software Maintenance Engineer, Virtualization Red Hat EMEA <https://www.redhat.com/> <https://www.redhat.com/>

Single Node Hyperconverged - Failing Engine Deployment - Network setup?
by jhamiltonactually＠gmail.com 15 Feb '21

15 Feb '21

Ovirt newbie here - installing v 4.4.4 (well, trying to!) Following my post about failing Gluster setup, I can't get the self hosted engine to deploy. I'm installing on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up, but Im realizing I'm missing something here. I have a feeling my problems with Gluster/Engine were caused by incorrect network setup. Seems I'm not the 1st to fall at this hurdle - some people in the community are saying RH have made it's deliberately difficult to get these 'free' set-ups working. It does feel a little like that! Most instructions just say that a 'self hosted, hyperconverged, single node setup requires 2 nics' - and that's about it! That is the 'Networking Pre-requisites'! I've had some help on here and Reddit which eventually made me find a solution some had had to use - editing lvm.conf to make sure my drive (sdb) was being blacklisted correctly. So, with that, Gluster installs, with following DNS settings: The kvm host (ovirt-kvm.whichelo.com) is fixed ip 192.168.0.40 on my 1st nic (Enp0s7) ovirt-engine.whichelo.com - 192.168.0.50 and ovirt-gluster.whichelo.com on 192.168.0.60 - I created I VLAN linked to the nic i want to use for gluster (Enp0s8) and gluster install worked. So now hosted engine won't install,, and pretty sure it's because I don't know how to set the network up properly. I'm seeing virbr0 coming up with different ip's - sometimes 192.168.1.1, sometimes 192.168.222.1. From what I've read, this is something to do with the Engine's network, but I really don't know! Am I still missing something? I can't find any decent instructions on how to do this - how (exactly) to configure the 2 'minimum required' nics? I came to Ovirt after realizing Oracle were dumping their own Virtualization platform in favour of KVM. Couldn't set it up from Oracle so moved to Red Hat - that was a no, and I was at the point where it made most sense to just run an Ovirt node for my KVM. I've got much further with Ovirt, but instructions do not work as easily as they looked! (example 'just click on single node hyperconverged' which didn't work straight off the bat until removing that LVM filter, which took days to find out! The single node HC server is a great match for a home lab/server like mine. I don't want another server, let alone another 2! I'm doing this partly as hobby, but also to update my skills during lockdown. Surely if we can get people using things like this at home, they're more likely to end up using it for work one day? Any help, or just pointing in the right direction, gratefully received! Hopefully I'm a biit clearer here. Happy to provide any logs or anything else.... Thank you!
