[Xen-users] Need help with networking in DomU's

[<datto@xxxxxxxxxxx>]

Fedora Core 4 Dom0 and CenOS 4.1 DomU as outlined similarly at Mark Foster's 
wiki which doesn't seem to be up at the moment.

uname -a on Dom0
Linux w2knt412 2.6.12.6-xen3_2.1_fc4 #1 SMP Sun Dec 4 11:19:39 PST 2005 i686 
i686 i386 GNU/Linux

Dom0 comes up and is on the network and I can VNC into Dom0 from other 
computers on the network just fine. However, my DomU's startup and seem to be 
useable from the DomU console but I can't get their networking to go out to the 
world. What changes do I need to make to which config files to get my DomU's to 
go out to the network and to the Internet? Thanks.
