+%description
+OVN (Open Virtual Network) is a series of daemons that translates
+virtual network configuration into OpenFlow, and installs them into
+Open vSwitch. OVN provides a higher-layer abstraction then Open vSwitch,
+working with logical routers and logical switches, rather than flows.
+OVN is intended to be used by cloud management software (CMS).
