I think with the interrupt status/timer issues sorted soon it's worth
maintaining migration from this release onwards, but I can say without
fear having been trying to get migration to work on various PPC/TCG
guests up until now that there is a < 10% of having a working image on
loadvm and without the macio fixes a very good chance of disk corruption
too.
