When stop a qemu vm via libvirt api, I call virDomainShutdown, I can seen the vm
shutdown process, But I call virDomainDestroyFlags with VIR_DOMAIN_DESTROY_GRACEFULL ,I
can't seen the vm shutdown process, virDomainDestroyFlags with
VIR_DOMAIN_DESTROY_GRACEFULL is gave vm driver process a SIGTERM , how vm driver process
SIGTERM signal (like qemu).
Thanks

The GRACEFUL flag isn't about allowing the guest OS to shutdown. It is the
difference between allowing QEMU to cleanly release resources, vs making
QEMU exit immediately. eg it allows pending / cached I/O operations to
complete before QEMU exits.
