 Building and Installing Open vSwitch for Linux

+
+Startup
+=======
+
+Before starting ovs-vswitchd itself, you need to start its
+configuration database, ovsdb-server.  Configure it to use the
+database you created during step 7 of installation, above, and to
+listen on a Unix domain socket, e.g.:
+
+      % ovsdb-server /usr/local/etc/ovs-vswitchd.conf.db --remote=punix:/usr/local/var/run/openvswitch/db.sock
+
+Then initialize the database with "ovs-vsctl init".  This is only
+necessary the first time after you create the database with
+ovsdb-tool (but running it at any time is harmless):
+
+      % ovs-vsctl init
+
+Then start the main Open vSwitch daemon, telling it to connect to the
+same Unix domain socket:
 
-Open vSwitch is configured primarily through a configuration file,
-whose name is specified on the ovs-vswitchd command line.  Please
-refer to ovs-vswitchd(8) and ovs-vswitchd.conf(5) for information on
-how to start ovs-vswitchd and the syntax of its configuration file,
-respectively.
+      % ovs-vswitchd unix:/usr/local/var/run/openvswitch/db.sock
 
-At runtime, you may make ovs-vswitchd reload its configuration file
-and update its configuration accordingly by sending it a SIGHUP
-signal.  The ovs-appctl utility can also be used to do this:
+Now you may use ovs-vsctl to set up bridges and other Open vSwitch
+features.  For example, to create a bridge named br0 and add ports
+eth0 and vif1.0 to it:
 
-    % ovs-appctl vswitchd/reload
+      % ovs-vsctl add-br br0
+      % ovs-vsctl add-port br0 eth0
+      % ovs-vsctl add-port br0 vif1.0
 
-In the latter case, ovs-appctl will wait for ovs-vswitchd to finish
-reloading before it exits.
+Please refer to ovs-vsctl(8) for more details.
