Hi Lucia,
I had to create an user for virsh:
# saslpasswd2 -a libvirt test

With that in mind, here’s the outputs:

Regarding the last two commands, I don’t have any VM running, since I cannot
start anything on the engine.
I’m starting to suspect that this may be something in the UEFI Firmware.
Any thoughts?
Thanks,

Hi,
oVirt CPU detection depends on libvirt (and that depends on qemu) CPU models.
Could you please run the following command to see what libvirt reports?
virsh domcapabilities
That should give you the list of CPUs known to libvirt with a usability flag
for each CPU.
If you find out that the CPU is not usable by libvirt, you might want to dig
deeper by querying quemu directly.
Locate any VM running on the system by
sudo virsh list --all
Use the name of a VM in the following command:
sudo virsh qemu-monitor-command [your-vm's-name] --pretty
'{"execute":"query-cpu-definitions"}'
That would give you the list of all CPUs supported by qemu and it will list all
cpu's features that are not available on your system.
Regards,
Lucia

Hi
I’ve an strange issue with two hosts (not using the hypervisor image) with EPYC
CPUs, on the engine I got this message:
The host CPU does not match the Cluster CPU Type and is running in a degraded
mode. It is missing the following CPU flags: model_EPYC. Please update the host
CPU microcode or change the Cluster CPU Type.
But it is an EPYC CPU, the firmware is updated to the latest versions, but for
some reason oVirt does not like it.
Here’s the relevant output from VDSM:
