[libvirt] [PATCHv3 01/43] snapshot: better event when reverting qemu to paused snapshot
When reverting a running domain to a paused snapshot, the event
that fires should mention that the domain is suspended.
* include/libvirt/libvirt.h.in
(VIR_DOMAIN_EVENT_SUSPENDED_FROM_SNAPSHOT): New sub-event.
* src/qemu/qemu_driver.c (qemuDomainRevertToSnapshot): Use it.
