Hi Qemu/KVM Devel Team,

Live Migration from a 0.12.2 qemu-kvm to a 0.12.3 (and 0.12.4)
does not work: "load of migration failed"

Is there any way to find out, why exactly it fails? I have
a lot of VMs running on 0.12.2 and would like to migrate
them to 0.12.4

Any hints would be appreciated!
Can you try reverting this patch?
