I was more thinking of running Xen on one node of a cluster, using it as the management tool. Each user gets his own VM on the master node, and can only access that. A real value would be if one could use the cluster resources from within a e.g. freebsd guest. So the question would be, can the processes of the guest OS be migrated to to other nodes? (openmosix can only migrate the userspace part of a process) Anyways i will try it next week. aha
