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: http://www.mail-archive.com/kvm@vger.kernel.org/msg34051.html I wonder why it is not noticed before -- it's broken since 0.12...
