I've just installed CentOS 6.4 an Xen on a new system, and eth0 is not found on dom0 when booting into Xen. When I boot into the 2.6.32 kernel outside Xen my network interface is found, using the e1000e driver. If I boot into Xen eth0 is not found, even if I modprobe the e1000e driver by hand. My NIC is an Intel I217-V.
Any suggestions for things I can do to get my network working inside Xen?
Thanks, Mark

Is it finding any other eth devices? (eth1, eth2, etc)
Verify the MAC address in the /etc/sysconfig/network-scripts/ifcfg-eth0 file matches what you have in the Xen configuration (xm list -l <hostname>). If not then remove it.

There is only one physical ethernet interface; no ethX is found under Xen. The MAC in ifcfg-eth0 is correct since it works just fine in the 2.6.32 kernel.

After looking at the kernel source, I see that the device ID for the i217 chip is missing from the 3.4.50 kernel, but is present in the 2.6.32 kernel. Looks like I need to open a bug report to have this backported.
