For libvirt, it seems only know the “Power State”? Anyway to read the
“powering-off” info?


The fact that you have asked nova to power off the instance means nothing to 
libvirt/qemu.


In the "nova stop" case nova will do some housekeeping stuff, optionally tell 
libvirt to shutdown the domain cleanly, then tell libvirt to destroy the domain, 
then do more housekeeping stuff.
