Live relocation currently requires the hardware of machines to be quite similar
(same CPU family and model). We decided that this might as well extend to the
software architecture too, so relocation from a host with a 32b dom0 to a 64b
dom0 will not work.

[Actually, its the dom0 version which is important rather than the hypervisor
version. You can probably live relo between an all-32b host and a 64b host
running 64b xen and a 32b dom0. Running a 32b dom0 on a 64b hypervisor is
actually a pretty smart thing to do anyhow as it tends to give slightly beter
performance.]

NB: Going forward, we aim to have live relocation work between hosts running
different releases of Xen.
