eth0 troubles with Xen guest on SLES 10 RC3

I have a default install of SLES 10 RC3 with the Xen
packages. When I
install a guest using the Virtual Machine Management module
in YaST it
does install fine except networking does not work. When the
VM boots up
the init scripts say: "No configuration found for
eth0". Which is
strange. I've tried going into YaST and configuring it,
nothing changes
but it does say: "The device does not have a driver
module. The driver
may be built in the kernel."

Is this a known bug? Or am I doing something wrong. On the
host system
ifconfig yields:

eth0 troubles with Xen guest on SLES 10 RC3

Check that all the following MAC addresses are in sync.  For
example
purposes assume the MAC to be used is 00:11:22:33:44:55.

1) On the host system, check the MAC used in the vm startup
script. 
The default script would be /etc/xen/vm/vm1.  Look for the
line 'vif = [
'mac=00:11:22:33:44:55' ]'

2) In the running vm, check which eth devices are shown in
/sys/class/net.  For each ethX directory shown cat the
address file. 
For example if you have a eth1 the 'cat
/sys/class/net/eth1/address'. 
There should be one eth device that has the address of 
00:11:22:33:44:55.  In your case it looks like it should be
eth0.

3) In the running vm,  check the interface configuration
files in
/etc/sysconfig/network.  There should be the file
'ifcfg-eth-id-00:11:22:33:44:55.

The MAC addresses from all three steps should match.  If not
then there
is some configuration issue.
