[pve-devel] [PATCH qemu-server v4 06/12] migrate: call vm_stop_cleanup after stopping in phase3_cleanup

[Dominik Csapak]

we currently only call deactivate_volumes, but we actually want to call
the whole vm_stop_cleanup, since that is not invoked by the vm_stop
above (we cannot parse the config anymore) and might do other cleanups
we also want to do (like mdev cleanup).

For this to work properly we have to clone the original config at the
beginning, since we might modify the volids.
