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,

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

Hi Leo, As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.

Failed to add storage domain

Hi! I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.

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

Ubuntu 18.04 and 16.04 cloud images hang at boot up
by suaro＠live.com 07 May '20

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.

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?

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.

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.

by Sandro Bonazzola 06 Apr '20

06 Apr '20

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: 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.

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.

I keep running into this error when I try to (re)deploy self-hosted engine. # ovirt-hosted-engine-cleanup # hosted-engine --deploy ... ... [ INFO ] TASK [ovirt.hosted_engine_setup : Fail with error description] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, deployment errors: code 9000: Failed to verify Power Management configuration for Host physhost01.example.com, fix accordingly and re-deploy."} I shut down all of the VM's and detached the storage before cleaning up and trying to re-deploy the hosted engine, first time I've run into this particular problem. Any help appreciated Brett

NFS permissions error on ISODomain file with correct permissions
by Shareef Jalloq 03 Apr '20

03 Apr '20

Hi, I asked this question in another thread but it seems to have been lost in the noise so I'm reposting with a more descriptive subject. I'm trying to start a Windows VM and use the virtio-win VFD floppy to get the drivers but the VM startup fails due to a permissions issue detailed below. The permissions look fine to me so why can't the VFD be read? Shareef. I found a permissions issue in the engine.log: 2020-03-25 21:28:41,662Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-14) [] EVENT_ID: VM_DOWN_ERROR(119), VM win-2019 is down with error.

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

You can upload to a Data Domain and when you highlight the VM in the management GUI, select the three dots in the top left for extra options and there is a change cd option. That option will allow for attaching an ISO from a Data Domain. That is what I recall when I was using oVirt a month or so ago. ________________________________________ From: eevans(a)digitaldatatechs.com <eevans(a)digitaldatatechs.com> Sent: Wednesday, March 25, 2020 2:28 PM To: 'Shareef Jalloq'; users(a)ovirt.org Subject: [ovirt-users] Re: Windows VirtIO drivers You have to copy the iso and vfd files to the ISO domain to make them available to the vm's that need drivers. engine-iso-uploader options list # engine-iso-uploader options upload file file file Documentation is found here: https://www.ovirt.org/documentation/admin-guide/chap-Utilities.html Eric Evans Digital Data Services LLC. 304.660.9080 [cid:image001.jpg@01D602B1.9FEA2EC0] From: Shareef Jalloq <shareef(a)jalloq.co.uk> Sent: Wednesday, March 25, 2020 1:51 PM To: users(a)ovirt.org Subject: [ovirt-users] Windows VirtIO drivers Hi, it seems the online documentation regarding the windows installation steps is well out of date.
