We do actually have a simple text based config file parser we use for
grokking the /etc/xen config files we could re-use. Technically the
files in /etc/xen are pure python, but our config parser only allows
plain strings, ints & lists so is safe to use. It can read and write
configs, preserving formatting.

Yeah, XML is fine for internal configs which a user doesn't need to touch,
but for admin facing configs in /etc/ we definitely want plain text
based format.
