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 -- PMM
