If you're into parsing logs, audit.log might be a better choice. I don't think we log things initiated from inside the guest, though - for example, an internal reboot. Event watching should probably give you what you want - but unless you were watching all the time you may miss transients, e.g. power-state changes. You can register to see only updates to VMs, which would cut down on the amount of uninteresting stuff you'd otherwise have to ignore. Jon
