           Summary: Network interface not available in domU
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux-2.6
            Status: NEW
          Severity: major
          Priority: P2
         Component: Hardware Support
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: Benjamin.Carleski@xxxxxxxxxxxxxxxxx

I am running Xen 3.0.2.  I am able to boot into Xen, and can use the network
fine from dom0, but when I create a domU, there is no network set up.  I have
not modified the network-bridge, vif-bridge, or xend-config.sxp.  I am using
the following configuration file for domU

#  -*- mode: python; -*-
kernel = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"
memory = 1984
vcpus = 2

disk = [ 'phy:vg01/vserver2,sda1,w' ]
vif = [ '' ]
hostname= "ispectrum-ui2"

root = "/dev/sda1"
extra ="3"

When I start the domain, I receive the following boot messages (abbreviated):
Bootdata ok (command line is 
root=/dev/sda1 3)
Kernel command line: 
root=/dev/sda1 3

I need help on how to configure this system so that I can get a working network
in the domU's.
