I have a dream, and the dream is to have an HA cluster running SLES as the virtualization host much like XenServer has for their HA ... mainly that if a host dies the VMs on that host get automatically restarted on the other host.

Is this possible? I can't really find much on this so I'm looking, first, at the "is this possible" side of things before I ask about the "how would you do this" sort of question.
