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.
