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-manager 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><br>

I can't check now what is in bios, but I will update with the status when I have a chance to check.<br>

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:<br>def _svm_enabled_by_bios(self):<br>....<br>
