Yeah, makes sense. Note that this is an entirely theoretical problem at the moment: TCG<->KVM migration isn't supported and won't work because the set of coprocessor registers each supports is different. (At some point we should probably fix this by getting TCG to support the right set of regs, but it's not a very high priority for me.) -- PMM
