CONFIGURATION FILES top 

       Following are the optional configuration files. If present, it should
       be located in the etc dir

   ovnnb-active.conf
       If present, this file should hold the url to connect to the active
       Northbound DB server

       tcp:x.x.x.x:6641

   ovnsb-active.conf
       If present, this file should hold the url to connect to the active
       Southbound DB server

       tcp:x.x.x.x:6642

   ovn-northd-db-params.conf
       If present, start_northd will not start the DB server even if
       --ovn-manage-ovsdb=yes. This file should hold the database url
       parameters to be passed to ovn-northd.

       --ovnnb-db=tcp:x.x.x.x:6641 --ovnsb-db=tcp:x.x.x.x:6642

RUNNING OVN DB SERVERS WITHOUT DETACHING top 

       # ovn-ctl run_nb_ovsdb

       This command runs the OVN nb ovsdb-server without passing the detach
       option, making it to block until ovsdb-server exits. This command
       will be useful for starting the OVN nb ovsdb-server in a container.

       # ovn-ctl run_sb_ovsdb

       This command runs the OVN sb ovsdb-server without passing the detach
       option, making it to block until ovsdb-server exits. This command
       will be useful for starting the OVN sb ovsdb-server in a container.

EXAMPLE USAGE top 

   Run ovn-controller on a host already running OVS
       # ovn-ctl start_controller

   Run ovn-northd on a host already running OVS
       # ovn-ctl start_northd

   All-in-one OVS+OVN for testing
       # ovs-ctl start --system-id="random"

       # ovn-ctl start_northd

       # ovn-ctl start_controller

   Promote and demote ovsdb servers
       # ovn-ctl promote_ovnnb

       # ovn-ctl promote_ovnsb

       # ovn-ctl --db-nb-sync-from-addr=x.x.x.x --db-nb-sync-from-port=6641
       demote_ovnnb

       # ovn-ctl --db-sb-sync-from-addr=x.x.x.x --db-sb-sync-from-port=6642
       demote_ovnsb
