I'd like to build a two or three node Pacemaker cluster that would manage Xen (or possibly KVM) virtual machines.

I'm in the process of configuring a sort-of Beowulf cluster, the major difference being that I want to be able to add nodes from any network. Because of this I can't run DHCP on the server to inventory all the nodes.
