Hi,
To sum up the issue - once xend start, the DNS dies, and the IP
tables gets thrashed. Whilst I could probably write paragraphs after
paragraphs of what I''ve done/tried etc, I figure a few copy & paste
will do... Networking isn''t really my area of expertise, but I can
see the routing is pretty messed up once xend starts. In addition,
eth0 in the xen domU is simply non-functional (no copy & paste from
domU for now, as I''m assuming once I''ve fixed dom0, domU will
then
work).
(in the following order:- edited ifconfig/route/ping)

Please read the docs about xen and networking in the wiki and the xen manual, then come back with questions instead of sending this mail and your whole net config again and again.
