I'm not really convinced that exposing disk allocation/capacity
information in the XML is appropriate. The XML is intended as a
representation of the guest hardware API and the host configuration.

The disk allocation/capacity info is neither of those things - it
is a statistic about the current state of the system. THis is
something that we'd usually report via dedicated APIs not the
XML.
