Some news:
I can't reproduce on my side currently (doing fio in guest when doing the disk
migrate).
If the target is slower, the migration %progression goes up and down, but when
I'm catching 100% it's ok.
Now, I have tell to the user forum to put a sleep, just before the
block-job-complete, and it's seem to resolve the problem.
So, maybe it's just a race condition, timeframe is short, but it's possible
"
s->common.offset = end * BDRV_SECTOR_SIZE; #from here we can call the
block-job-complete in proxmox code
if (!s->synced) {
block_job_event_ready(&s->common);
s->synced = true;
#but only from here it's ok
}
"
I don't known how much time take block_job_event_ready, to sent the event (I
think it's async, but I'm not sure)
I don't known if we could add something like
s->synced = true;
s->common.synced = true;
to get the sync status in query-block-job

Yes,I ll try to reproduce first, to be sure

Would you mind to ask on the qemu list?

I guess that is possible, because current code ($stat->{len} ==
$stat->{offset}) does the same thing.
