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

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

-Padma

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

Probably from the network-bridge script. Try running bash x
/etc/xen/scripts/network-bridge¹ before starting xend, and see which line of
that script causes the SIOCSIF error.

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

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 :-

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=eth2¹.
