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? johnn
