I've been using Xen on Fedora Core 4 without any problem.  Recently, I
upgraded (reinstalled from scratch) another Fedora Core 5 system.  I'm
having a difficult time getting a network interface configured for a
domU.  This is my configure file:

   kernel = "/boot/vmlinuz-2.6.16-1.2080_FC5xenU"
   memory = 1024
   name = "meta"
   vif = [ '' ]
disk = [ 'phy:xenvg/metaboot,sda1,w', 'phy:xenvg/metaroot,sda2,w',
'phy:xenvg/   metausr,sda3,w', 'phy:xenvg/metavar,sda4,w',
'phy:xenvg/metaswap,sda5,w' ]
   vtpm = [ 'instance=1,backend=0' ]
   root = "/dev/sda2 ro"
   extra = "3"

I've also tried this line for the vif:

   vif = [ 'mac=00:16:3e:00:00:11, bridge=xenbr0' ]

However, I'm still not able to get eth0 in domU to work.

[root@meta ~]# ifconfig eth0 192.168.1.10 netmask 255.255.255.0
SIOCSIFADDR: No such device
eth0: unknown interface: No such device
SIOCSIFNETMASK: No such device
SIOCGIFADDR: No such device
SIOCSIFBROADCAST: No such device

I'm seeing this in xend.log:

What am I missing?  Any help is appreciated.
