This sounds like it could fix the corruption issues we have been experiencing when doing drive-mirror's on RBD.

First patch use new "ready" flag introduce in qemu 2.2, to finish block migration.
It's the right way to known if we can complete the job. (same flag than qmp ready event)
(I have also remove the vm pause when target is too slow, it don't work fine in my tests,
and we can't rely on offset==len to known if the transfert is correctly finished.
Second patch increse a lot a drive-mirror qmp, because the job is scanning the whole
source image before return.
This can be very long with big image on nfs for example.
