[Xen-users] DomU - Network not routing

[Aero_nomad <nomad@xxxxxxxxxx>]

Hello, 

I installed Xen on Centos 5 as given in 
http://www.howtoforge.com/centos_5.0_xen

My current network requirement is exactly same as the one explained at 
http://www.debian-administration.org/articles/360

Everything worked fine , until I had to setup the network.

DomU is unable to ping to outside network . It does not even reach its 
gateway .  Please let me know where I'm going wrong . Pasting the route & 
ifconfig of DomU and Dom0 

Regards,
Soj
