Which packages to install

Install openvswitch if you need OpenFlow virtual switch function. It contains ovs-vswitchd, ovsdb-server and helper utilities such as ovs-vsctl, ovs-ofctl, ovs-ctl etc.

Linux kernel datapath module openvswitch.ko will also be installed along with package openvswitch. Tunnel encap support for gre, geneve, vxlan can be included by installing kmod-openvswitch-{gre,geneve,vxlan} respectively

For OVN deployment

  • Install openvswitch-ovn-north for ovs-northd, ovsdb-server, ovn helper utitlies
  • Install openvswitch-ovn-host for ovn-controller and openvswitch

How to use them

Open vSwitch provides a few very useful helper script in /usr/share/openvswitch/scripts/. A simple initscript is provided. It's mainly a wrapper around ovs-ctl and ovn-ctl with simple knobs from /etc/config/openvswitch. Procd is not used here.

/etc/init.d/openvswitch start
/etc/init.d/openvswitch stop
/etc/init.d/openvswitch stop north
/etc/init.d/openvswitch restart ovs
/etc/init.d/openvswitch status

Use ovs-ctl and ovn-ctl directly for more functionalities
