Just to make sure I got it right:
You want to create multiple virtual linux instances and have openmosix migrate 
those instances arround your cluster?

I don't think that that would be possible with xen. OpenMosix migrates 
processes on operating system level, whereas Xen adds another scheduler 
beneath the OS. It might be remotely possible with user mode linux, where 
linux instances are mapped to Host OS Processes. 
But I doubt you'd get any usefull performance with that setup.
