Hello,
I've tried many times to run a node as a guest in ovirt following
http://wiki.ovirt.org/wiki/Vdsm_Developers#Running_Node_as_guest_-_Nested_KVM
. The result is that I'm able to register such a host in engine, but
it is impossible to start any vm on it. If I boot on an ISO, I can see
the first prompt and move between the items. But since I begin the
installation I have a blank screen and the vm goes into pause mode in
vit-manager. Then I have no way else than rebooting the hypervisor
guest because it is impossible to resume. When I get logs on the real
host, I can find this :

As you can see, I have tried many cpu type for launching this guest
hypervisor, but none of them is accepted by the hypervisor. Plus, I've
modified each time the family type in the cluster tab, but it is the
same.
On the hist:
#virsh capabilities gives
<cpu>
<arch>x86_64</arch>
<model>Westmere</model>
<vendor>Intel</vendor>
Thanks for your help
What does the command 'qemu-kvm -cpu ?' give ? Could you please try
the following guest cpu definition?
*
<cpu match='exact'>
<model>core2duo</model>
<feature policy='require' name='vmx'/>
</cpu>
