perfered node / fencing

I'm sure this has a simple answer, but spammers have beat me into a pulp and I need a break..

Can I specify a preferred node for a VM and have it used when fencing occurs? I would like it say stay on node 4 but if node 4 goes down, it does it thing. Then once node 4 is restored. have the VM go back to it.

Or is it as simple as where the VM resides when its placed in HA? Is the "owner" the preferred node?
