Centos7 Installing the openvswitch Virtual Switch

What is Open vSwitch?

Open VSwitch is a production quality, multilayer Virtual Switch licensed under the Open Source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard manage  ment interfaces and protocols (e.g. NetFlow, SFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag). In addition, it's designed to support distribution across multiple physical servers similar to VMware ' s vnetwork distribu Ted Vswitch or Cisco ' s Nexus 1000V. See full Feature List here
