1 | How to Install Open vSwitch on Red Hat Enterprise Linux |
| 2 | ======================================================= | |
| 3 | ||
| 4 | This document describes how to build and install Open vSwitch on a Red | |
| 5 | Hat Enterprise Linux (RHEL) host. If you want to install Open vSwitch | |
| 6 | on a generic Linux host, see INSTALL.Linux instead. | |
| 7 | ||
| 8 | We have tested these instructions with RHEL 5.6 and RHEL 6.0. | |
| 9 | ||
| 10 | Building Open vSwitch for RHEL | |
| 11 | ------------------------------ | |
| 12 | ||
| 13 | You may build from an Open vSwitch distribution tarball or from an | |
| 14 | Open vSwitch Git tree. | |
| 15 | ||
| 16 | Before you begin, note the RPM source directory on your version of | |
| 17 | RHEL. On RHEL 5, the default RPM source directory is | |
| 18 | /usr/src/redhat/SOURCES. On RHEL 6, it is $HOME/rpmbuild/SOURCES. | |
| 19 | ||
| 20 | 1. If you are building from an Open vSwitch Git tree, then you will | |
| 21 | need to first create a distribution tarball by running "./boot.sh; | |
| 22 | ./configure; make dist" in the Git tree. | |
| 23 | ||
| 24 | 2. Copy the distribution tarball into the RPM source directory. | |
| 25 | ||
| 26 | 3. Unpack the distribution tarball into a temporary directory and "cd" | |
| 27 | into the root of the distribution tarball. | |
| 28 | ||
| 29 | 4. To build Open vSwitch userspace, run: | |
| 30 | ||
| 31 | rpmbuild -bb rhel/openvswitch.spec | |
| 32 | ||
| 33 | This produces two RPMs: "openvswitch" and "openvswitch-debuginfo". | |
| 34 | ||
| 35 | 5a. On RHEL 5, to build the Open vSwitch kernel module, copy | |
| 36 | rhel/kmodtool-openvswitch-el5.sh into the RPM source directory and | |
| 37 | run: | |
| 38 | ||
| 39 | rpmbuild -bb --target=i686-unknown-linux \ | |
| 40 | rhel/openvswitch-kmod-rhel5.spec | |
| 41 | ||
| 42 | You might have to specify a kernel version, e.g.: | |
| 43 | ||
| 44 | rpmbuild -bb -D "kversion 2.6.18-238.12.1.el5" \ | |
| 45 | --target=i686-unknown-linux \ | |
| 46 | rhel/openvswitch-kmod-rhel5.spec | |
| 47 | ||
| 48 | This produces a "kmod-openvswitch" RPM for each kernel variant, | |
| 49 | which is usually: "kmod-openvswitch", "kmod-openvswitch-xen", and | |
| 50 | "kmod-openvswitch-PAE". | |
| 51 | ||
| 52 | 5b. On RHEL 6, to build the Open vSwitch kernel module, run: | |
| 53 | ||
| 54 | rpmbuild -bb rhel/openvswitch-kmod-rhel6.spec | |
| 55 | ||
| 56 | This produces an "kmod-openvswitch" RPM. | |
