Does the guest crash perhaps? In which case a kernel log from it
might turn out pretty useful. As would technical data (rather than
a simple "does not work") in the first place (hypervisor, xend, and
Dom0 kernel logs are all possible candidates for holding relevant
information).

Does migration fail in both directions? Or perhaps just from the
newer to the older system (in which case I would guess you're
not masking features properly on the newer one)?
