Open vSwitch on Fedora Linux

This document provides instructions for building and installing Open vSwitch RPM packages on a Fedora Linux host. Instructions for the installation of Open vSwitch on a Fedora Linux host without using RPM packages can be found in the general installation guide.

These instructions have been tested with Fedora 23, and are also applicable for RHEL 7.x and its derivatives, including CentOS 7.x and Scientific Linux 7.x.

Build Requirements

To build packages for a Fedora Linux host, you will need the packages described in the general installation guide. Specific packages (by package name) include:

  • rpm-build
  • autoconf automake libtool
  • systemd-units openssl openssl-devel
  • python python-twisted-core python-zope-interface python-six
  • desktop-file-utils
  • groff graphviz
  • procps-ng

And (optionally):

  • libcap-ng libcap-ng-devel
  • dpdk-devel

Bootstraping

Refer to the Bootstrapping section of the general installation guide.

Configuring

Refer to the Configuring section of the general installation guide.

Building

User Space RPMs

To build Open vSwitch user-space RPMs, execute the following from the directory in which ./configure was executed:

$ make rpm-fedora

This will create the RPMs openvswitch, python-openvswitch, openvswitch-test, openvswitch-devel, openvswitch-ovn-common, openvswitch-ovn-central, openvswitch-ovn-host, openvswitch-ovn-vtep, openvswitch-ovn-docker, and openvswitch-debuginfo.

To enable DPDK support in the openvswitch package, the --with dpdk option can be added:

$ make rpm-fedora RPMBUILD_OPT="--with dpdk"

The above commands automatically run the Open vSwitch unit tests, which can take several minutes. To reduce the build time by disabling the execution of these tests, the --without check option can be added:

$ make rpm-fedora RPMBUILD_OPT="--without check"

Kernel OVS Tree Datapath RPM

To build the Open vSwitch kernel module for the currently running kernel version, run:

$ make rpm-fedora-kmod

To build the Open vSwitch kernel module for another kernel version, the desired kernel version can be specified via the kversion macro. For example:

$ make rpm-fedora-kmod \
     RPMBUILD_OPT='-D "kversion 4.3.4-300.fc23.x86_64"'

Installing

RPM packages can be installed by using the command rpm -i. Package installation requires superuser privileges.

The openvswitch-kmod RPM should be installed first if the Linux OVS tree datapath module is to be used. The openvswitch-kmod RPM should not be installed if only the in-tree Linux datapath or user-space datapath is needed. See the FAQ document for more information about the various Open vSwitch datapath options.

In most cases only the openvswitch RPM will need to be installed. The python-openvswitch, openvswitch-test, openvswitch-devel, and openvswitch-debuginfo RPMs are optional unless required for a specific purpose.

The openvswitch-ovn-* packages are only needed when using OVN.

Refer to the RHEL README for additional usage and configuration information.
