[libvirt] Trying to debug "Received unexpected event 3" from libvirt

Hi, I'm trying to debug this issue, which may be affecting my inability to perform live snapshot. 1. I'm not sure what 'Waking up a tragedian" in the debug log means - what exactly is a tragedian? 2. In any case, it'd be great if the WARN would mention mon->await_event - is it the event libvirt is actually waiting for? (Both from qemu/qemu_agent.c) 3. I reckon event 3 is QEMU_AGENT_EVENT_RESET ? (from qemu/qemu_agent.h) 4. I'm also getting 'End of file while reading data: Input/output error' messages, not sure what they mean yet. (using 1.2.18.2-1 on FC23, trying to live-snapshot VMs (with Centos 6 & 7 in them, all with qemu guest agent, AFAIK). TIA, Y.
