RE: [Xen-devel] new /etc/xen/network script

[Li Ge <lge@xxxxxxxxxx>]

Ok, I modifed the script. Here is the new result:

After I started xend, the network connection of dom0 lost.

I did "ifdown eth0" and "ifup eth0" here. Still the network did not come up.

This is new log info from /var/log/xend.log:

Argghh. There's a really stupid bug in the script.

Please edit the following line:

-if ! ifdown ${netdev} ] ; then
+if ! ifdown ${netdev} ; then

I'm not sure that the extraneous ']' is actually the problem, though.

Please can you add a `which ifdown` just before that line.

Thanks,
Ian
