[CentOS-virt] networking problems with kernel 2.6.18-8.1.15.el5xen

[Johnn Tan]

Today I installed a core CentOS-5 (--nobase). After that, I 
"yum update", rebooted, then "yum install xen kernel-xen".

When I boot into the xen kernel, I can't get networking on 
eth0. It can ping itself, but not anything else. There are 
no routes listed, when I try to add a default gateway, it 
just says there's no network reachable.

When I change /boot/grub/grub.conf back to non-xen kernel 
(same version), networking works again.

Has anyone else updated to the latest CentOS-5 xen kernel?
