Конфигурационный файл (Config file)
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.

RUNNING OVN DB SERVERS WITHOUT DETACHING
# 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

       # 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
