Yes, but you will have to write your own custom fencing script for that and configure it as explain in
http://www.ovirt.org/Custom_Fencing (look in the oVirt 3.5 section)

If you need any details, please ask but mainly you should look on the scripts in the fence-agents package (/usr/sbin/fence_*) and write something that supports the common flags used by those scripts
