Re: [Xen-devel] Xend error: SIOCSIFNAME : Device or resource busy

If you want to attach real ethernet device eth2 to teh bridge then the correct command line is ‘bash –x /etc/xen/scripts/network-bridge start netdev=eth2’.

Using the script suggested I tied to start bridge on eth2
So bash –x /etc/xen/scripts/network-bridge vifnum=2 start. It gives the following output. Nothing happening on eth2 :-

Probably from the network-bridge script. Try running ‘bash –x /etc/xen/scripts/network-bridge’ before starting xend, and see which line of that script causes the SIOCSIF error.

Hi
 
I have the latest xen-unstable and the veth devices do not get created. When I start xend, I get this error message. However xm works. I am able to create VMs.
However bridges do not work.
 
I have tried several “xen-unstable” versions so would appreciate any help
 
Thanks
