You mean by bisecting between qemu 1.2 and 1.3? I retested qemu 1.2 and
it wasn't 100% working for me there too. It worked fine until
migrate_downtime 1s it breaks / vm just halts when i set it to 2s with
qemu 1.2. So i don't really know where to start bisecting. As i have NO
version where it worked perfectly. Except Qemu 1.3 with the patches
backported from 1.4 this works fine.
