Yousong Zhou c2f788f054 openvswitch: rework packaging 
New scheme mainly provides three packages: openvswitch,
openvswitch-ovn-north, openvswitch-ovn-controller.  These should fit
most usage scenarios.  Other subpackages like openvswitch-libXXX
etc.  are there for dependency management and are hidden from the
menu.

Many python and shell scripts are removed in this revision.  Most of
them cannot run out of box at all for lack of dependencies.  Others
being legacy ones are not that useful now.  Add them back at later time
when real need appears

Below are a simple listing of additions

 - initscript now incorporate also ovn north and controller support
 - ovn-ctl and ovs-ctl can be invoked directly from within $PATH

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

TODO

ovn

  • controller init
  • ls, lsp, lr, lrp
  • qos
  • nat
  • ovsdb cluster
