Thank you, everybody. You agree about that what I'm thinking is not a
good idea, or at least, it is very difficult. I am sure that it's
dificult and I don't know if I will get something that worths it.
I have been reading the Xen Roadmap and it says that in Xen 3.0 release, one new feature will be:
- Cluster management. We wish to add tool support to provide
a better unified interface to managing a cluster of Xen machines. This
would include features such as automatic use of VM live-migration to
load-balance across a cluster, and the ability to 'evacuate' VMs from
a node before shutting it down for maintenance etc.
And this is what I am looking for!!!, I thought that I could do this on
OpenMosix, but you say that I have to look for another Cluster
Technology, which one? Have you ever done something like this?

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.
