Actually I think it is relatively easy to support migration from BOTH qemu and qemu-kvm. By adding a _runtime_ command-line switch (such as --qemu-kvm-compat, which has been already mentioned in other context), which modifies that migration stuff (machine definitions) in a reasonable way. It can be done based on this patchset I guess (when it will be polished and proven to work well). And after that is done, this configure option can go away. How do you guys think? Thanks! /mjt
