I haven't attempted to reproduce the issue recently, I'm afraid. I've changed jobs twice in the intervening time, so the immediate issue for me has gone away. If I find an opportunity, I shall try to reproduce with the most recent versions.

Because the KVM system dies, the underlying VM is obviously terminated.
