For migration incoming side, it either quit in precopy or postcopy. It
is safe to use the mis->bh for both instead of allocating a dedicated
QEMUBH for postcopy.

Hi Wei,
  Can you check this, the patchew tests came back with a failure which
seems bh related; I've not tried it, but can you just see if you can
reproduce it?

Hmm... the error message in mail is a little confusion.

I see following error, but have no idea about what it is.

I am trying to reproduce it. I guess docker should be used. Would you mind
sharing some link on setup the environment.
