I'm still not convinced it would work since > /etc/init.d/networking is called before openvswitch is running. It would work if you call the "--allow=ovs" command in /etc/init.d/openvswitch-switch. But it is probably a problem if you have some dependent directories mounted through network and you want have all network interfaces through OVS.

And when new bridges are created, you go and look up /etc/network/interfaces for any post creation commands. I am not aware of any way you can do this right now. > > Thanks, > -Tim >
