Hi, need a help!
may be the problem is very simple, but I've not found solution:
-oVirt 4.5.4 on RHEL 8.7
-amd_iommu is on on the Host with Nvidia Card A40
I can see my cards in vGPU Settings for Windows VMs (Windows 10 Pro).
Without activation of the vGPU device VM started normally.
With one active vGPU card VM cannot start. Error message on the Host:

Looks like libvirtd cannot get any device. Is it problem of Nvidia settings on the host or
Problem of VM settings?
Thank you

You mention amd_iommu but you are using Nvidia and I doubt this is the correct approach.
Have you checked the procedure
at: https://access.redhat.com/documentation/en-us/red_hat_virtualization/...
seems quite extensive and if your Nvidia supports vGPU, you can give it a try.

Hi Strahil,
thank you for your emal.
I’ve repeat all steps from the Manual. I think, my problem deals with kernel rebuild
(dracut –force). I’ve repeat again – VM can be started, NVIDIA Card can be configured.
During Start I can see another errors on the Host:
kernel: [nvidia-vgpu-vfio] b21e49d5-c13c-4695-83b8-212cd2f0830a: vGPU migration disabled
vdsm[4487]: ERROR Error getting managedvolume connector info: Managed Volume Helper
failed….. No module named
\\\'importlib_resources\\\'\\n\<file:///'importlib_resources/'/n/>''
But my first problem looks solved.
Regards
Pawel

New subject: Cannot open Portal under Alias Name
Hi Strahil,
maybe you can help me again:
I’ve set Alias Name with SSO_ALTERNATE_ENGINE_FQDNS=…..
I can reach the first Page under the alias name, but if I klick for example on
“Administration Portal”, I receive 500 Error.
Error_log shows something like:
auth_openidc:error…the "state" and "session" cookies will not be
shared between the two!
But it seems not to be a problem.
Thank you in advance
Regards
Pawel
