Thanks for your reminder. I think fence_virsh or fence_virt can be 
leveraged to achieve the goal..
For fence_virsh, it requires virsh to be installed on the vdsm virtual 
host. For fence_virt, it requires
fence_virtd to be installed on the vdsm virtual host and it is not 
libvirt centric. With these two
power management protocol, the oVirt engine still need change to 
integrate these two protocols for
the host power management.
