[Xen-users] Problem with network bridge when starting domU
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 tried "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
&nb!
sp; peth0
