I think, this is a very interesting question.
Xen has to be able to create and bringup the guest on both machines
and they need to be synchronized via live migration mechanism.
I think with Xen''s PoD feature, Xen can bring up the guest with 12GB
RAM on a
8GB machine and then Xen needs to be able to move it partially to the second
machine.
Also scheduling of vcpu''s on physical cpus has to be handled, i.e.
first half
of vcpus is scheduled on first machine, second half on second machine.
I don''t think this is possible with Xen now but this is surely a nice
feature
for a future Xen version.
