First development version of OpenNode OS with Open vSwitch is available for public testing from opennode-dev yum repository - replacing older linux bridge code and introducing new exciting features.
We have temporarely setup a separate opennode-ovs yum repository - http://opennodecloud.com/CentOS/6/opennode-dev/ - for OpenNode OS with Open vSwitch (OpenNode-OVS) development process.
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 management interfaces and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In addition, it is designed to support distribution across multiple physical servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V. See the full feature list here
OpenNode-OVS is currently available only as OpenNode OS yum upgrade from opennode-ovs repository. For activating opennode-ovs repository please edit /etc/yum.repos.d/opennode.repo file - by changing opennode-test repo URL final part to opennode-ovs and setting repo section enable parameter to 1 (and disabling opennode stable repo). Then please execute: "yum clean all && yum update".
NB! After yum update system reboot is needed in order to activate openvswitch (you may safely ignore openvswitch related errors on first shutdown).
