How to Install Open vSwitch on Fedora Linux
===========================================
This document describes how to build and install Open vSwitch on a Fedora
Linux host. If you want to install Open vSwitch on a generic Linux host,
see [INSTALL.md] instead.
We have tested these instructions with Fedora 23. These instructions are also
used for RHEL 7.x and its derivatives, such as CentOS 7.x.
Building Open vSwitch for Fedora
--------------------------------
You may build from an Open vSwitch distribution tarball or from an
Open vSwitch Git tree.
The default RPM build directory (_topdir) has five directories in
the top-level:
1. BUILD/ Where the software is unpacked and built.
2. RPMS/ Where the newly created binary package files are written.
3. SOURCES/ Contains the original sources, patches, and icon files.
4. SPECS/ Contains the spec files for each package to be built.
5. SRPMS/ Where the newly created source package files are written.
Before you begin, note the RPM sources directory on your version of
Fedora. The command "rpmbuild --showrc" will show the configuration
for each of those directories. Alternatively, the command "rpm --eval
'%{_topdir}'" shows the current configuration for the top level
directory and the command "rpm --eval '%{_sourcedir}'" does the same
for the sources directory. On Fedora 23, the default RPM _topdir is
$HOME/rpmbuild and the default RPM sources directory is
$HOME/rpmbuild/SOURCES.
1. If you are building from a distribution tarball, skip to step 2.
Otherwise, you must be building from an Open vSwitch Git tree.
Create a distribution tarball from the root of the Git tree by
running:
```
./boot.sh
./configure
make dist
```
2. Now you have a distribution tarball, named something like
openvswitch-x.y.z.tar.gz. Copy this file into the RPM sources
directory, e.g.:
`cp openvswitch-x.y.z.tar.gz $HOME/rpmbuild/SOURCES`
3. Make another copy of the distribution tarball in a temporary
directory. Then unpack the tarball and "cd" into its root, e.g.:
```
tar xzf openvswitch-x.y.z.tar.gz
cd openvswitch-x.y.z
```
4. To build Open vSwitch userspace, run:
`rpmbuild -bb rhel/openvswitch-fedora.spec`
This produces one RPM: "openvswitch".
To enable DPDK support in the resulting openvswitch package,
add `--with dpdk` to the build command.
The above command automatically runs the Open vSwitch unit tests.
To disable the unit tests, run:
`rpmbuild -bb --without check rhel/openvswitch-fedora.spec`
5. On Fedora 23, to build the Open vSwitch kernel module, run:
`rpmbuild -bb rhel/openvswitch-kmod-fedora.spec`
You might have to specify a kernel version and/or variants, e.g.:
```
rpmbuild -bb \
-D "kversion 4.3.3-300.fc23.x86_64” \
-D "kflavors default debug kdump" \
rhel/openvswitch-kmod-fedora.spec
```
This produces an "kmod-openvswitch" RPM for each kernel variant,
in this example: "kmod-openvswitch", "kmod-openvswitch-debug", and
"kmod-openvswitch-kdump".
