This directory contains files for seamless integration of Open vSwitch on Citrix XenServer hosts managed by the Citrix management tools. Some of these files are modifications of Citrix's proprietary code. Citrix has given permission to distribute these modified files. Citrix has not specified a particular license for them. There is no guarantee that, should Citrix specify a license, that it would be DFSG-compliant or GPL-compatible. Most of the files in this directory is installed on a XenServer system under the same name, if underscores are replaced by slashes. The files are: etc_init.d_openvswitch Initializes Open vSwitch at boot and shuts it down at shutdown. etc_init.d_openvswitch-xapi-update Init script to ensure openvswitch-cfg-update is called for the current host at boot. etc_logrotate.d_openvswitch Ensures that logs in /var/log/openvswitch are rotated periodically and that appropriate daemons reopen their log files at that point. etc_profile.d_openvswitch.sh Open vSwitch-related shell functions for the administrator's convenience. etc_xapi.d_plugins_openvswitch-cfg-update xapi plugin script to update the cache of configuration items in the ovs-vswitchd configuration that are managed in the xapi database when integrated with Citrix management tools. etc_xensource_scripts_vif Open vSwitch-aware replacement for Citrix script of the same name. openvswitch-xen.spec spec file for building RPMs to install on a XenServer host. opt_xensource_libexec_interface-reconfigure Open vSwitch-aware replacement for Citrix script of the same name. usr_share_openvswitch_scripts_monitor-external-ids Daemon to monitor the external_ids columns of the Bridge and Interface OVSDB tables. usr_share_openvswitch_scripts_refresh-xs-network-uuids Script to refresh Bridge table external-ids:xs-network-uuids values, which can get out-of-sync following a pool join. usr_share_openvswitch_scripts_sysconfig.template Template for Open vSwitch's /etc/sysconfig/openvswitch configuration file. usr_lib_xsconsole_plugins-base_XSFeatureVSwitch.py xsconsole plugin to configure the pool-wide configuration keys used to control Open vSwitch when integrated with Citrix management tools. usr_sbin_brctl wrapper for /usr/sbin/brctl that provides some additional bridge compatibility usr_sbin_xen-bugtool Open vSwitch-aware replacement for Citrix script of the same name. uuid.py This is uuid.py from Python 2.5. It is installed into the Open vSwitch RPM because XenServer 5.5 and 5.6 use Python 2.4, which do not have uuid.py. To install, build the Open vSwitch RPM with a command like this: rpmbuild -D "openvswitch_version $full_version" \ -D "xen_version $XENKERNEL" \ -D "build_number --with-build-number=$buildnr" \ -bb openvswitch-xen.spec Then, "rpm -U" the resulting Open vSwitch package on the XenServer hosts in question and reboot them. (The openvswitch-dbg package that is also produced need not be installed, but it is harmless to do so.) ---------------------------------------------------------------------- Copyright (C) 2009, 2010 Nicira Networks, Inc.
