I disagree :-)  I think cloning is a pretty high level operation and
is better off outside the core libvirt API, building on top of the
various APIs libvirt provides (or should provide). The most obvious
set of missing APIs which are needed for clone are the storage management
APIs we've discussed a few times in the past. Sooner or later we're 
going to have to tackle those APIs, since even regular guest provisioning
will need them once we have remote support.
