README.Debian for openvswitch-switch
---------------------------------
-* To use the Linux kernel-based switch implementation, you will need
- to build and install the Open vSwitch kernel module. To do so, install
- the openvswitch-datapath-source package, then follow the instructions
- given in /usr/share/doc/openvswitch-datapath-source/README.Debian
+To use the Linux kernel-based switch implementation, you will need an
+Open vSwitch kernel module. There are multiple ways to obtain one.
+In order of increasing manual effort, these are:
-* This package does not yet support the userspace datapath-based
- switch implementation.
+ * Use a Linux kernel 3.3 or later, which has an integrated Open
+ vSwitch kernel module.
+
+ The upstream Linux kernel module lacks a few features that
+ are in the third-party module. For details, please see the
+ FAQ, "What features are not available in the Open vSwitch
+ kernel datapath that ships as part of the upstream Linux
+ kernel?".
+
+ * Install the "openvswitch-datapath-dkms" Debian package that
+ you built earlier. This should automatically build and
+ install the Open vSwitch kernel module for your running
+ kernel.
+
+ This option requires that you have a compiler and toolchain
+ installed on the machine where you run Open vSwitch, which
+ may be unacceptable in some production server environments.
+
+ * Install the "openvswitch-datapath-source" Debian package, use
+ "module-assistant" to build a Debian package of the Open
+ vSwitch kernel module for your kernel, and then install that
+ Debian package.
+
+ You can install the kernel module Debian packages that you
+ build this way on the same machine where you built it or on
+ another machine or machines, which means that you don't
+ necessarily have to have any build infrastructure on the
+ machines where you use the kernel module.
+
+ /usr/share/doc/openvswitch-datapath-source/README.Debian has
+ details on the build process.
+
+ * Build and install the kernel module by hand.

----------------------------------
The following OVS specific "command" options are supported:
- - ovs_type: This can either be OVSBridge, OVSPort, OVSIntPort or OVSBond
- depending on whether you configure a bridge, port, an internal port or
- a bond. This is a required option.
+ - ovs_type: This can either be OVSBridge, OVSPort, OVSIntPort, OVSBond or
+ OVSTunnel depending on whether you configure a bridge, port, an internal
+ port, a bond or a tunnel. This is a required option.
- ovs_ports: This option specifies all the ports that belong to a bridge.
- ovs_bonds: This option specifies the list of physical interfaces to be
bonded together.
+ - ovs_tunnel_type: For "OVSTunnel" interfaces, the type of the tunnel.
+ For example, "gre", "vxlan", etc.
+
+ - ovs_tunnel_options: For "OVSTunnel" interfaces, this field should be
+ used to specify the tunnel options like remote_ip, key, etc.
+
- ovs_options: This option lets you add extra arguments to a ovs-vsctl
command. See examples.
