1 | How to Install Open vSwitch on Citrix XenServer |
| 2 | =============================================== | |
| 3 | ||
| 4 | This document describes how to build and install Open vSwitch on a | |
| a320b341 | 5 | Citrix XenServer host. If you want to install Open vSwitch on a |
| 4b11d5e8 BP |
6 | generic Linux host, see INSTALL.Linux instead. |

8 | These instructions have been tested with XenServer versions 5.5.0, |
| 9 | 5.5.0-24648p (Update 1), 5.5.0-25727p (Update 2), and 5.5.900. | |

11 | Building Open vSwitch for XenServer |
| 12 | ----------------------------------- | |
| 13 | ||
| 14 | The recommended build environment to build RPMs for Citrix XenServer | |
| 15 | is the DDK VM available from Citrix. If you are building from an Open | |
| 16 | vSwitch distribution tarball, this VM has all the tools that you will | |
| 17 | need. If you are building from an Open vSwitch Git tree, then you | |
| 18 | will need to first create a distribution tarball elsewhere, by running | |
| 19 | "./boot.sh; ./configure; make dist" in the Git tree, because the DDK | |
| 20 | VM does not include Autoconf or Automake that are required to | |
| 21 | bootstrap the Open vSwitch distribution. | |
| 22 | ||
| 23 | Once you have a distribution tarball, copy it into | |
| 24 | /usr/src/redhat/SOURCES inside the VM. Then execute the following: | |
| 25 | ||
| 26 | VERSION=<Open vSwitch version> | |
| 27 | XENKERNEL=<Xen kernel version> | |
| 28 | cd /tmp | |
| 29 | tar xfz /usr/src/redhat/SOURCES/openvswitch-$VERSION.tar.gz | |
| 30 | rpmbuild \ | |
| 31 | -D "vswitch_version $VERSION" \ | |
| 32 | -D "xen_version $XENKERNEL" \ | |
| 33 | -bb openvswitch-$VERSION/xenserver/vswitch-xen.spec | |
| 34 | ||
| 35 | where: | |
| 36 | ||
| 37 | <openvswitch version> is the version number that appears in the | |
| 38 | name of the Open vSwitch tarball, e.g. 0.90.0. | |
| 39 | ||
| 40 | <Xen kernel version> is the version number of the Xen kernel, | |
| 41 | e.g. 2.6.18-128.1.1.el5.xs5.5.0.487.1006xen. This version number | |
| 42 | appears as the name of a directory in /lib/modules inside the VM. | |
| 43 | It always ends in "xen". | |
| 44 | ||
| 45 | Two RPMs will be output into /usr/src/redhat/RPMS, whose names begin | |
| 46 | with "vswitch" and "vswitch-debuginfo". | |
| 47 | ||
| 48 | Installing Open vSwitch for XenServer | |
| 49 | ------------------------------------- | |
| 50 | ||
| 51 | To install Open vSwitch on a XenServer host, or to upgrade to a newer | |
| 52 | version, copy the "vswitch" RPM to that host with "scp", then install | |
| 53 | it with "rpm -U", e.g.: | |
| 54 | ||
| 55 | scp vswitch-$VERSION-1.i386.rpm root@<host>: | |
| 56 | (At this point you will have to enter <host>'s root password.) | |
| 57 | ssh root@<host> | |
| 58 | (At this point you will have to enter <host>'s root password again.) | |
| 59 | rpm -U vswitch-$VERSION-1.i386.rpm | |
| 60 | ||
| 61 | To uninstall Open vSwitch from a XenServer host, remove the package: | |
| 62 | ||
| 63 | ssh root@<host> | |
| 64 | (At this point you will have to enter <host>'s root password again.) | |
| 65 | rpm -e vswitch | |
| 66 | ||
| 67 | After installing or uninstalling Open vSwitch, the XenServer should be | |
| 68 | rebooted as soon as possible. | |
