In that case, can you post a fresh version of the live migration series?  Paolo
is obviously willing to take a big chunk of that series, and it will likely be
easier to review with the full context, e.g. one of my comments on the standalone
encryption bitmap series was going to be that it's hard to review without seeing
the live migration aspect.

Thanks!
