Thanks Ben for quick response! Really appreciate it.

How do I create a transaction so that the newly created "controller" is 
referred? I can see the "Bridge" has a column controller, but it 
requires the controller's uuid, which is created automatically and 
returned by ovsdb. Since the controller is GC'ed immediately after my 
transaction, seems like I cannot get a hold on it...

Thanks!
