not really. the patch is here to have an openmosix kernel running under
Xen as Mark said.

openMosix is not what you are looking for, because openMosix migrates
object at the process level, whereas VM are a whole operating system.

At a basic start, you can write a small application that will
communicate with other node for gathering lots of heuristic (cpu load,
mem load, ...) and execute xm migrate locally.

that might look like an openmosix userspace scheduler actually.
