failed to bring up eth0 from Dom0 (SIOCSIFADDR: No such device)

[Joris Dobbelsteen]

The paravirtualized installation does not recognize the ethernet controller properly (for some reason).

I've a quite similar problem on my guest installations.

I have this problem on a Ubuntu Dapper that now again runs on vmWare. I also have this problem on a paravirtualized Debian Etch (2 new ones currently).

The problem seems to be closely related to the fact that the Linux kernel does not correctly detect your network card, for whather reason. Check out "dmesg" to see if it is actually loaded. You should see some lines that contain "eth0". So "dmesg | grep eth0" is a good starting point.

Another thing I discovered somewhere is that it might come up under a different name (for some very odd reason).
Do a "find /sys -iname *eth*" and see what that turns up. This might show the actual interface has a different name. I used udev to correct this problem for me.

Please check that
