How to Install Open vSwitch on Red Hat Enterprise Linux
=======================================================
This document describes how to build and install Open vSwitch on a Red
Hat Enterprise Linux (RHEL) host. If you want to install Open vSwitch
on a generic Linux host, see INSTALL.Linux instead.
We have tested these instructions with RHEL 5.6 and RHEL 6.0.
Building Open vSwitch for RHEL
------------------------------
You may build from an Open vSwitch distribution tarball or from an
Open vSwitch Git tree.
Before you begin, note the RPM source directory on your version of
RHEL. On RHEL 5, the default RPM source directory is
/usr/src/redhat/SOURCES. On RHEL 6, it is $HOME/rpmbuild/SOURCES.
1. If you are building from an Open vSwitch Git tree, then you will
need to first create a distribution tarball by running "./boot.sh;
./configure; make dist" in the Git tree.
2. Copy the distribution tarball into the RPM source directory.
3. Unpack the distribution tarball into a temporary directory and "cd"
into the root of the distribution tarball.
4. To build Open vSwitch userspace, run:
rpmbuild -bb rhel/openvswitch.spec
This produces two RPMs: "openvswitch" and "openvswitch-debuginfo".
5a. On RHEL 5, to build the Open vSwitch kernel module, copy
rhel/kmodtool-openvswitch-el5.sh into the RPM source directory and
run:
rpmbuild -bb --target=i686-unknown-linux \
rhel/openvswitch-kmod-rhel5.spec
You might have to specify a kernel version, e.g.:
rpmbuild -bb -D "kversion 2.6.18-238.12.1.el5" \
--target=i686-unknown-linux \
rhel/openvswitch-kmod-rhel5.spec
This produces a "kmod-openvswitch" RPM for each kernel variant,
which is usually: "kmod-openvswitch", "kmod-openvswitch-xen", and
"kmod-openvswitch-PAE".
5b. On RHEL 6, to build the Open vSwitch kernel module, run:
rpmbuild -bb rhel/openvswitch-kmod-rhel6.spec
You might have to specify a kernel version and/or variants, e.g.:
rpmbuild -bb \
-D "kversion 2.6.32-131.6.1.el6.x86_64" \
-D "kflavors default debug kdump" \
rhel/openvswitch-kmod-rhel6.spec
This produces an "kmod-openvswitch" RPM for each kernel variant,
in this example: "kmod-openvswitch", "kmod-openvswitch-debug", and
"kmod-openvswitch-kdump".
Red Hat Network Scripts Integration
-----------------------------------
Simple integration with Red Hat network scripts has been implemented.
Please read rhel/README.RHEL in the source tree or
/usr/share/doc/openvswitch/README.RHEL in the installed openvswitch
package for details.
