POWER9 (ppc64le) Support on oVirt 4.4.1
by Vinícius Ferrão
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.
Machine info:
timebase : 512000000
platform : PowerNV
model : 8335-GTH
machine : PowerNV 8335-GTH
firmware : OPAL
MMU : Radix

Select host for image upload
by C Williams
Hello,
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
varying speeds.
Somehow oVirt keeps wanting to select my oldest and slowest system to use
for image uploads.
Please Help !
Thank You !

Q: Failed creating snapshot
by Andrei Verovski
Hi,
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.

Question about OVN MTU
by Strahil Nikolov
Hello All,
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.
Best Regards,
Strahil Nikolov

Training Video or document or training session
by info＠worldhostess.com
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
online training.
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.
Yours Sincerely,
Henni

Does oVirt 4.3.10 supports RHEL 7.9 hosts ?
Is it safe to update ovirt 4.3.10 hosts to the latest RHEL 7.9 ?
Thank you.

Install test lab single host HCI with plain CentOS as OS
by Gianluca Cecchi
Hello,
if I want to install a test lab environment of type single host HCI and
want to use CentOS 8.2 as the OS for the host, can I still use the
graphical wizard from cockpit? I see it accessing the server...
Or is it thought only to be run from ovirt-node-ng system?
In case it is not possible is there a command line workflow I can use to
get the same as the wizard playbook run?
BTW: I want to use CentOS for this test lab because I need to install
custom packages (for performance counters and other things) so I'd prefer
the flexibility to have a plain CentOS and not the NG node.
Thanks in advance,
Gianluca
