[Users] ovirt and nested virtualization

Hello, suppose that I have a f18 3.2.1 node that starts with nested virtualization activated # systool -m kvm_intel -v|grep nested nested = "Y" Is there any way to configure in oVirt a CentOS 6.x guest where I can then use hardware virtualization? So is there a way to pass to the guest the vmx flag of the cpu and other necessay flags for it (or something like copy to guest as in virt-manager)? Gianluca
