Hi all!
We've faced a bug in rhev-2.12.0-33.el7-based Qemu.
In upstream, bug introduced in 4.0 by 74da6b943565c45
"block/dirty-bitmaps: implement inconsistent bit" commit.
At this commit we started to load inconsistent bitmap instead of
silently ignoring them, and it now I see that it breaks migration.
The fix is very simple, so I think it's OK for 4.2.. Still, it's not a
degradation, so we may postpone it to 5.0.
