Wow! This sounds very cool.

If Xen really *does* completely hide the underlying hardware, so that 
virtual OSes running have no "way" of knowing what their hardware is, I 
really see it as a big plus.
I think I can tolerate about 1 hour of downtime per server if the work 
is done at night, so I guess migration won't be a big issue then.
Cheers,
Jean-Michel.
