Hi
I notice that the CPU in kvm is detected as Opteron_G3 after running "virsh -r
capabilities | grep model" and there is no support in ovirt UI, is it possible to
added by modify the postal database in the engine?
From kvm the host seems good

Hi all
I am running OLVM 4.5, this is a test setup which was running in my old workstation with
Intel CPU and is nested virtualization (with VMWare Workstation), the host was running
Windows 7 x64, I moved to AMD Ryzen 7950X3D a couple of days ago which runs Windows 11 x64
with 128GB memory then moved OLVM VM's from the old workstation to this new
workstation.
The problem I face now is the KVM hosts shows this error
Host kvm1 moved to Non-Operational state as host CPU type is not supported in this cluster
compatibility version or is not supported at all
I modified /etc/modprobe.d/kvm.conf and changed
options kvm_amd nested=0
to
options kvm_amd nested=1
reboot the kvm host but still getting same error, I verified the modification and seems
good
[root@kvm1 ~]# cat /sys/module/kvm_amd/parameters/nested
1
In Windows 11 I have hyper-v off and Memory Integrity is also off.
Am I missing any additional steps?
Thanks
