Is there a way that I can register with libvirt for the state change notifications in the guest OS?
Thanks Eric. Understand that there is no such facility at the libvirt level. Do you know whether such notification can be received/trapped at the qemu level itself ? I had once checked that QEVENT_RESET event is emitted when the guest OS reboots.
Certain guest events such as shutdown ARE detected by qemu, and therefore feed a lifecycle event that you can then monitor via libvirt. We even have an example program shipped in the libvirt sources for tracking all events in the lifecycle of a domain. However, I don't know if a guest reboot is always detected by qemu. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
