 Q: What is Open vSwitch?
 
 A: Open vSwitch is a production quality open source software switch
-   designed to be used as a vswitch in virtualized server environments.  A
-   vswitch forwards traffic between different VMs on the same physical host
-   and also forwards traffic between VMs and the physical network.  Open
-   vSwitch supports standard management interfaces (e.g. sFlow, NetFlow,
-   RSPAN, CLI), and is open to programmatic extension and control using
-   OpenFlow and the OVSDB management protocol.
