How to build Linux ha resources for xen to enable vm based fail over?

Hey everyone, I'm trying to setup a 2 host highly available xen cluster using lvm backed by iscsi on a third host, I've gotten manual migrations working perfectly and I have heartbeat setup and seeing the hosts online or offline. What I am trying to figure out is how to create the cluster resources for the vm's themselves so if I hard shutdown host1; host2 would take over the vm's they do not need to be --live migrated (which works manually) homogenous ubuntu 12.10 OS

After I fix host1 and add it back it should take the vm's back

Any help on this would be appreciated emmensely.
