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?
Right! Thank you so much. It was a typo while converting the legacy code to better syntax. Had no AMD to test... :) Fixed. http://gerrit.ovirt.org/#/c/9758/ commit a271c2a8d53cbf13d639188bc5c3c0c9779cdebc Author: Cristian Falcas <cristi.falcas@gmail.com> Date: Thu Dec 6 09:12:35 2012 +0200 vdsm: hardware: fix typo in amd virtualization detection Change-Id: I2deb8f7ab0f306b15edc7b8238325ef6c359e809 Signed-off-by: Alon Bar-Lev <alonbl@redhat.com> diff --git a/src/plugins/ovirt-host-deploy/vdsm/hardware.py b/src/plugins/ovirt-host-deploy/vdsm/hardware.py index c4685aa..275d1c8 100644 --- a/src/plugins/ovirt-host-deploy/vdsm/hardware.py +++ b/src/plugins/ovirt-host-deploy/vdsm/hardware.py @@ -111,7 +111,7 @@ class Plugin(plugin.PluginBase): MSR_VM_CR = 0xc0010114 vm_cr = self._prdmsr(0, MSR_VM_CR) - return (vm_cr & (1 << SVM_VM_CR_SVM_DISABLE)) != 0 + return (vm_cr & (1 << SVM_VM_CR_SVM_DISABLE)) == 0 def _check_kvm_support_on_power(self): with open('/proc/cpuinfo', 'r') as f:
