The virDomainSaveStatus/virDomainEventNewFromObj calls need to be moved up inside the "if (vm->state != VIR_DOMAIN_PAUSED) {" conditional, since you don't want to dispatch an event if its already paused.

Same as above - the virDomainSaveStatus/virDomainEventNewFromObj cals need to be moved inside the "if (vm->state == VIR_DOMAIN_PAUSED) " conditional Aside from that, this patch looks good.
