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=20 8GB machine and then Xen needs to be able to move it partially to the secon= d=20 machine. Also scheduling of vcpu's on physical cpus has to be handled, i.e. first ha= lf 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 featu= re for a future Xen version.
