Xen users - Jul 2007 - eth0 does not exist when booting to xen kernel

Hi everyone.

I am pretty new to xen, but am having an issue that I can''t seem to
crack.
I am running the 2-6-16 kernel on Debian Etch.  If I boot into the Etch
kernel, everything works as it should.  When I boot into the Xen kernel,
eth0 no longer exists.
>From what I understand, the network-bridge script will down my eth0, create
a new virtual eth0 and bridge it into xenbr0

However, ifconfig only shows my lo and xenbr0 interfaces.  ifconfig -a lists
all the veth devices and the vif devices, but still no eth0

/etc/xen/scripts/network-bridge status returns ''Device "eth0"
does not
exist.

lsmod shows that the e1000 driver is loaded.

Can anyone shed some light?

Thanks,
-John

I guess that is due to udev.

Does 

ifconfig -a 

show the nic somewhere (eth1, eth2, ...)?


If the answer is yes, look at /etc/udev/rules.d/z25_persistent-net.rules
I guess udev has mapped the device somewhere else.

Nope, ifconfig -a shows lo, veth0-veth7 and vif0.0-vif0.7 and xenbr0.

Hi John,

What is your network adapter?

I''m not sure whether this is a hint or not, but you may need to
recompile the Xen Kernel to add support to your specific hardware.

I had the same issue. Yes it is that he never compiled the Driver in
the kernel. But what you can do to see if it is working is do a
modprobe e1000 and then do a ifconfig -a and then see if the card
comes up!
