While looking at the events reported by said script I noticed that there
are no events for creating / deleting snapshot, at leat when the VM is
inactive. For an active VM Qemu reports several events:
  VIR_DOMAIN_EVENT_DEFINED_FROM_SNAPSHOT
  VIR_DOMAIN_EVENT_STOPPED_FROM_SNAPSHOT
  VIR_DOMAIN_EVENT_STARTED_FROM_SNAPSHOT
  VIR_DOMAIN_EVENT_SUSPENDED_FROM_SNAPSHOT
  VIR_DOMAIN_EVENT_RESUMED_FROM_SNAPSHOT

Also there is no event generated when doing "virsh change-media" for an
inactive domain; I would have expected an
VIR_DOMAIN_EVENT_DEFINED_UPDATED event.
For an active domain you get the
libvirt.VIR_DOMAIN_EVENT_TRAY_CHANGE_OPEN / CLOSE events.

My current work-around is to do polling, but I want to get rid of that.
Did I miss something or is it okay to add events for tha?

Thanks in advance.
