Bug Description
Hi,
there are another bug. Simptoms: VM with heavy load stop responding on ssh connection and VNC (through KVM). After I shutdown VM (virsh destroy XX) Newly created machines do not work and produce error on screenshot.
When one VM died others continue work but after it destroyed/shutdown all new machines have the same error message.
Regards,
