Hello, I was using oVirt 4.3.10 with IBM AC922 (POWER9 / ppc64le) without any issues.
Since I’ve moved to 4.4.1 I can’t add the AC922 machine to the engine anymore, it complains with the following error:
The host CPU does not match the Cluster CPU type and is running in degraded mode. It is missing the following CPU flags: model_POWER9, powernv.
Any ideia of what’s may be happening? The engine runs on x86_64, and I was using this way on 4.3.10.
timebase : 512000000
platform : PowerNV
model : 8335-GTH
machine : PowerNV 8335-GTH
firmware : OPAL
MMU : Radix

Generally speaking, you should follow the hosted-engine backup and
I strongly suggest to test this first on a test machine before production.
You can take a backup without downtime.
Restore on some machine (can be a VM, with nested-kvm) that has no
access to your production storage and hosts (to make sure the restored
engine won't start managing them/competing with the production one).
See that all looks good. Then plan production...
Good luck and best regards,
I've migrated my iSCSI storage to a new array, and the only thing remaining is to migrate the hosted-engine.
Any directions on how I should proceed. I understand that I will need to back-up the existing, create a new hosted-engine on the new storage, specifying the backup a reference.
I just would like to see a step-by-step, so I know I am doing everything, and in the right order.
I am having problems selecting the host that I want to use for .iso and
other image uploads via the oVirt Web Console. I have 20+ servers of
Somehow oVirt keeps wanting to select my oldest and slowest system to use
for image uploads.
Please Help !
Thank You !
I have oVirt 4.4 with nodes 4.2.8
Attempt to create snapshot failed with:
EventID 10802 VDSM node11 command SnapshotVDS failed: Message timeout can be caused by communication issues.
Event ID 2022 Add-disk operation failed to complete.
However, snapshot is on disk since VM now takes 1200GB instead of 500.
Yes snapshot list in VM details is empty.
How to recover disk space occupied by unsuccessful snapshot ?
I looked at /vmraid/nfs/disks/xxxx-xxxx-xxx/images
and there are no distinctive files which I can identify as snapshot.
Thanks in advance.
in our environment we need to either specify proxy settings or use foreman/katello repositories.
I'd like to test both ways but the installer with the ansible scripts behind don't seem to use the hosts settings.
Where do I have to adopt the install scripts and will there be in future a GUI option to specify those things?
Can't understand why disconnected environments or environments with proxies aren't better taken into consideration...?
Thanks in advance,
I would like to learn more about OVN and especially the maximum MTU that I can use in my environment.
Current Setup 4.3.10
Network was created via UI -> MTU Custom -> 8976 -> Create on External Provider -> Connect to Physical Network
So my physical connection is MTU 9000 and I have read that Geneve uses 24 bits (maybe that's wrong ?) , thus I have reduced the MTU to 8976.
I did some testing on the VMs and ping with payload of '8914' was the maximum I could pass without fragmenting and thus the MTU on the VMs was set to 8942.
Did I correctly configure the test network's MTU and am I understanding it correctly that we need extra 34 bits inside the network for encapsulation ?
I have checked https://www.ovirt.org/develop/release-management/features/network... but I don't see any refference how to calculate the max MTU.
I forgot to check "Discard after Delete" when creating a new volume. Is
there a way (other than to empty the volume) to reclaim free blocks.
In https://bugzilla.redhat.com/show_bug.cgi?id=981626 I read about
blkdiscard, but as far as I understand it will erase my VMs ...
Thanks for your answers
Can someone recommend a training video of some kind of step by step document
to do the installation and administration for OVirt? Or if someone that
wants to do a one on one online training? I would be super excited to do
I have been trying many time to install and I am sure I make some mistakes
because I can't get OVirt to work properly.
I have done numerous installations during the last few weeks.
