Hi,

I have started domU successfully. I am using the default xend-config.sxp, it uses (network-script network-bridge). But my domU doesn't get any IP information, and it's disconnected from dom0 and rest of the world.

While booting domU, I get the following message:
...
Bringing up loopback interface: [ OK ]
Bringing up interface eth0:
Determining IP information for eth0... failed.
[FAILED]
....

At the same time, my /var/log/xen- hotplug.log records:

xenstore-read: couldn't read path backend/vbd/5/777/physical-device
xenstore-read: couldn't read path backend/vif/5/0/ip

pings from domU to outside world/dom0 IP fail.

I read networking issues in archives and other tutorials, but haven't yet found any solution.

Can anyone tell me what might be going wrong? Or at least where should I look to probe further?

Thanks a lot.
