Let's nail down the transitions that we plan to support, then, just as I
did earlier for domains.
It would be even cooler to have a life cycle diagram with the API used
to transition between states documented somewhere. I seem to recall
seeing one for domains once, but couldn't find it in 5 minutes of
searching right now.
Found it:
http://libvirt.org/guide/html-single/#Application_Development_Guide-Guest...
That diagram completely lacks transient domains. It also shows
persistent/running to persistent/inactive via Shutdown, while I
mentioned Destroy (both APIs work for that transition, although Shutdown
requires guest response).
Something that could certainly use some TLC!
