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)
