There are at least 1 other problem in the migration code that's
worth looking at (IMHO anyway): namely, migration on 32 bit host
is completely (as far as i can see) broken (instant kvm process
crash) in 0.12, but it works on 64bits:

I wonder why it is not noticed before -- it's broken since 0.12...

Thanks!
