Well, the migration won't fail with an error, but on the destination
end you'll end up with a device in its reset state but a guest which
may think the device is in some other state. If the device was
quiescent and doesn't need complex setup it might cope, but
more likely is that that guest driver will fall over in a heap next
time you try to use it...
