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,

Hi,<br>
<br>
The latest otopi installer is failing with the following error:<br>
<br>
virtualization support AuthenticAMD (cpu: True, bios: False)<br>
and<br>
RuntimeError: Hardware does not support virtualization<br>
<br>
Running rdmsr also says that virtualization is not enabled in bios:<br>
./rdmsr --bitfield 4:4 0xc0010114<br>
0<br>
<br>
Is the bios flag mandatory for virtualization? On the same machine virt-man=
ager works and can start virtual machines.<br>
<br>

oVirt is based on KVM which requires full virtualization (bios flag enabled=
).<br>
In your case, looks like virt-manager is using pure qemu to emulate.<div><b=
