+============
+Open vSwitch
+============
+
+Open vSwtich (OVS) is a software switch commonly used in OpenStack deployments
+to replace Linux bridges as it offers advantages in terms of mobility, hardware
+integration and use by network controllers.
+

+OPNFV Installers
+================
+
+Currently not all installers are supported.
+
