I've just checked with the one responsible for the mess. Is it correct, that even when
we have this bug, we would not be able to delete the snapshot when there is not at least
the same amount of storage free as the snapshot is? d'oh...

> We have tried to delete a Snapshot and it hangs at merging the snapshots. We've
found out that this is a known bug because the merge process is being called with wrong
parameters according to the bug report
https://bugzilla.redhat.com/show_bug.cgi?id=1601212. The Snapshot's Disks are in
illegal state and the VM is locked. Since it is a very important VM for our non-profit
organization, we need to have this machine back online as soon as possible. Is there a way
to fix this without updating to qemu-kvm-ev-2.12.0? At least back to the state before the
deletion would be fantastic.
