I am trying to set up a driver domain for a NIC. I exposed the NIC to the DomU. 
Now I am trying so that other guest domains can use this network card.

I am facing the following problem:
Suppose my driver domain has id=1 and the guest domain has id=2.

How will the interface vif2.0 come up in the driver domain when I boot the 
guest domain. Where should I specify the script to be run on the driver domain 
whenever a new guest domain is booted.

I use the following vif line in configuration file:

vif = [ ' ', 'bridge=xenbr0', 'backend=1' ]

Backend=1 specifies the driver domain, but how to create and add a backend 
interface to the bridge in driver domain when a new domain is booted?

Any hint in this direction will be helpful.

Thanks,
Purav
