How to Install 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 INSTALL.md.

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

The tools and packages that are required for building Open vSwitch are documented in INSTALL.md. 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

Building Open vSwitch RPMs for Fedora

RPMs may be built from an Open vSwitch distribution tarball or from an Open vSwitch Git tree. The build procedure for each scenario is described below.

Preparing to Build Open vSwitch RPMs with a GIT Tree

From the top-level directory of the git tree, execute the following commands:

./boot.sh
./configure

Preparing to Build Open vSwitch RPMs from a Tarball

From a directory with appropriate permissions, execute the following commands (substituting the relevant Open vSwitch release version for "x.y.z"):

tar xzf openvswitch-x.y.z.tar.gz
cd openvswitch-x.y.z
./configure

Building the User-Space RPMs

To build Open vSwitch user-space RPMs, after having completed the appropriate preparation steps described above, 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"

Building the Kernel OVS Tree Datapath RPM

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

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 Open vSwitch RPMs

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 FAQ.md 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.

See [rhel/README.RHEL] for additional usage and configuration information.
