Subject: [Xen-devel] Networking in Xen
Hello,
I have computer which is not connected to the internet (its eth0 is
assigned 10.10.0.13 statically and is UP). I am running Xen 3.0.2 on
it.
I want my domU to be able to ping the dom0 and vice versa (I am
assigning 10.10.0.14 to the domU).
I tried a bridged connection, but when I tried to ping 10.10.0.13 from
the domU I get the message "connect: Network is unreachable". When I
pinged the domU from dom0 I got "Destination Host Unreachable"
What sort of a networking should I set up to achieve this? (I have
shown ifconfig, route and iptabes below).
Any help is appreciated
Thanks,
Girish
my ifconfig from dom0 looks like
