The Open vSwitch teamÂ announced the availability of Open vSwitch 1.0.0.Â Open vSwitch is a multilayer virtual switch licensed under the open source Apache 2 license.
TheÂ goal is to build a production quality switch for VM environments that supports standard management interfaces (e.g. NetFlow, RSPAN, ERSPAN, IOS-like CLI), and is open to programmatic extension and control.Â In addition, it is designed to support distribution across multiple physical servers similar to VMwareâ€™s distributed vswitch or Cisco’s Nexus 1000V.
Open vSwitch currently supports multiple virtualization technologies. It is the default switch in the Xen Cloud Platform. Â And it supports open source Xen, XenServer, KVM, and VirtualBox.Â The bulk of the code is written in platform-independent C and is easily ported to other environments.
