Actually I added support for this a few weeks back

Tue Nov 14 18:42:01 EST 2006 Daniel Berrange <berrange at redhat.com>

        * src/xend_internal.c: Added support for parsing non-bridge style
        networking configs for guests.
        * src/xml.c: Ensure the <ip address> element gets serialized to
        the SEXPR for non-bridged networks.
        * tests/xml2sexprtest.c, tests/sexpr2xmltest.c: Added new tests
        covering different networking configs
        * tests/xml2sexprdata/, tests/sexpr2xmldata/: Added more data
        files for new test cases

Regards,
Dan.
