In case you haven't yet, it may be a worth you having a look at: http://www.gentoo.org/doc/en/xen-guide.xml and the way it suggests you create bridged interfaces. There's also some links at the bottom of the page that may be of interest. HTH. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
