I guess that this patch only reports percentage for the initial bulk copy of

I haven't tested this scenario, but the next phase, sending dirty blocks, can
be quite long too if the guest does a lot of I/O.
Won't it give a wrong impression to the user when qemu says "Completed 100%"
but disk migration continues catching up for a while?
