xen still break DNS/routing

[William John Murray]

  Hello there,
             A couple of weeks ago I~ posted that xen was breaking
'host' and other routing commnds. This is still true. I just tried the
2.6.12-1.1454_FC4xen0 rpm from 'riel'.
    One suggestion I got was 'strace route', so I tried this.
By comparing normal and xen-enabled results, the first change I see is
that when "my-gateway" appears on the normal host, the xen enabled
xernel finds  "my-machine" appearing instead. Somehow it is trying to
use itself as a gateway.

I do see the following xen eth setup in /var/log/messages

   Can anyone suggest anything?
   Thanks,
