 I'm also getting a migration problem with current HEAD: right
when the migration process finishes the destination guest
reboots.

 Reverting the above commit doesn't fix the problem, though.

 Also, it's been hard to 'bisect' it because:

1. doesn't appear to be caused by a recent commit
2. taking too old 'good' commits makes 'bisect' hit all
   recent migration bugs

 So, not sure what to do here... Maybe I'll go over committed
series manually.
