I was actually playing with this today, and just put up a review that adds
a devstack exercise to create and launch a bootable volume.  It is true
that --image is still required when booting from a volume - I have not
investigated yet if that is a bug or a consequence of how boot-from-volume
is implemented as an extension (which still may fall into the bug category).

Hopefully the code above will give you some direction to get started.  My
experience thus far is that the end-to-end experience of using this feature
needs some work, so I'll probably file some bugs and patches while I muck
with it.  So it would be great if you took a look and did the same:)
