You might want to think twice before doing that, or at least have
some alternative story about how you'd do administration of a
pool of VMs running over a cluster of nodes. 

I guess you're probably thinking of multi-level secure VMs on a
single host (e.g. a laptop), but the cluster side is important

I guess it might be possible to weld xm and xend directly to each
other in the single machine case.
