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,
