Is it really down ?
Have you tried to migrate it to another host.
I found out yesterday that one of my VMs was constantly reporting errors (relayed to
snapshot delete) and the errors stopped when the system got migrated to another host.
Best Regards,

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.
