Hi,
The latest otopi installer is failing with the following error:
virtualization support AuthenticAMD (cpu: True, bios: False) and RuntimeError: Hardware does not support virtualization
Running rdmsr also says that virtualization is not enabled in bios: ./rdmsr --bitfield 4:4 0xc0010114 0
Is the bios flag mandatory for virtualization? On the same machine virt-manager works and can start virtual machines.
oVirt is based on KVM which requires full virtualization (bios flag enabled). In your case, looks like virt-manager is using pure qemu to emulate.
I can't check now what is in bios, but I will update with the status when
I have a chance to check.
Sure.

I checked and I had virtualization enabled in bios. Also, I was mistaken and the result from rdmsr means bios is ok: result is supposed to be 0 (based on kvm-ok script). I did the test with and without virtualization enabled in bios and I got this: - enabled = 00000100 - disabled= 00011000
From internet: Bit 4 of MSR 0xc0010114 returns 0 means virtualization enabled
Based on this, I think that the check in /usr/share/ovirt-host-deploy/plugins/ovirt-host-deploy/vdsm/hardware.py it should not be != 0, but: def _svm_enabled_by_bios(self): .... (vm_cr & (1 << SVM_VM_CR_SVM_DISABLE)) == 0 I think the above means (8 & (1 << 4)) which is 0? Best regards,
