Dear all we are desperate 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.
