I think we should care about migration on all architectures
and devices, in the sense that we want savevm/loadvm to work.
This is a really useful debugging and user tool, and when
I'm reviewing devices it's the minimum bar I think new
devices should clear. You then get migration "for free" but
I don't particularly expect it to be used compared to
snapshot save/restore. (Of course some of our existing code
doesn't support this, and we don't have a good way of testing
so bugs creep in easily, but as a principle I think it's
good.)
thanks
