Thanks for the reminder to follow up on list.

To summarize my read of this thread, the strong consensus seems to be to

of nova itself.  It also seems there's no universally agreed upon
alternative location for it within the existing components, though the
plugable asynchronous import proposal for glance seems like a sensible

What we've opted to do for the moment is focus on expanding our original
standalone proof of concept to support more operating systems and more
cleanly support both network and DVD/iso based installs, in part based
on the expanded block device mapping work that Nikola has been doing.

We're also working on a smaller/targeted enhancement to nova to allow
specifying a kernel command line, in addition to a ramdisk and kernel
when booting an instance.  This will allow us to avoid crafting custom
boot media when installing Linux under both KVM and, most likely, Xen
hypervisors.  Dennis' initial patch set for this:
