On a particular system, you run one ovsdb-server instance and one ovs-vswitchd
instance. ovs-vswitchd will connect to ovsdb-server to get its configuration.
When you run ovs-vsctl (or ovsdb-tool or ovsdb-client), it also connects to
your ovsdb-server instance to change or retrieve the configuration (which is
then sent to ovs-vswitchd).
In ovsdb-server, there is a table called "Open_vSwitch", which has a single
row. This is the root of your configuration. You can see a diagram of how the
other tables connect to the root here:

A description of how to create the database and get the daemons running is in
the "Startup" section of the INSTALL.Linux file:
