Once we have the next release of libvirt out of the way, I want to tackle
the task of unifying all the XML parsers and XML generators. The storage
APIs have a single parser & generator for all the different backends. I
believe we can do the same for the domain XML and thus dramatically reduce
the amount of work required to add new drivers, as well as reducing the
amount of code we have to manitain & keep in sync.
