U can do two thing, just comment out vif line 
and specify the ramdisk it to config file.

Thanks,

Hi all,

I am new to Xen and I ran into some problem when trying to
xm create a FC6 domU with Xen 3.1. My dom0 is a FC5 running
the 2.6.18-xen kernel. This might just be a stupid configuration
issue that I am not aware of so please bear with me.

Here is what my cfg file looks like:

kernel = "/boot/vmlinuz-2.6.18-xen"
memory = 256
name = "fedora.fc6"
disk = ['file:/home/ljohnson/stuff/xen/fc6/fedora.fc6.img,sda1,w',
'file:/home/ljohnson/stuff/xen/fc6/fedora.swap,sda2,w']
root = "/dev/sda1 ro"
vif = [ '' ]

I was able to start the domain without the virtual nic. However,
with the vif in the cfg file, I got the following error when
creating the domain:

Error: Device 0 (vif) could not be connected. Could not find bridge, and none was specified

I have already turned off iptables on my machine and dom0's network
seems to work fine. I have also used "vif = [ '', "bridge=xenbr0' ] but
the same error still shows up. If I set the mac address myself by
"vif = [ 'mac=00:16:3e:00:00:11, bridge=xenbr0' ]", xm create hangs
and attempt to switch to the domU's console with "xm consle fedora.fc6"
also hangs. Any suggestion on where to look ?

The output from brctl show:
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif0.0
