Thanks SalvatoreI am thinking these:1) openvswitch has more features than 
quantum, so i want to support it in pandora first, then later to support 
quantum2) openvswitch seems doesn't provide API, still don't know how to 
control it programatically. May be i send command in command-pipeline then 
parse the output. But this is not a good practice.3) i want to do 
live-migration with auto network transfer in pandora. So i need to control a 
vswitch.

Thanksfrom Peter

Yes, it is a very common use case.Nowadays, everybody who deploys Xen, KVM, or 
LXC without a Cloud Management System is actually using Open vSwitch.In that 
case you can program Open vSwitch using its own interface to provide virtual 
networks.

When deploying Openstack, you can use Open vSwitch without Quantum by deploying 
nova-network instead.As far as I know every nova-network manager works with 
Open vSwitch too.
