The default DATABASE, if none is given, is
/etc/openvswitch/conf.db.

JSON-RPC options (may be specified any number of times):
  --remote=REMOTE         connect or listen to REMOTE

Active JSON-RPC connection methods:
  tcp:HOST:PORT           PORT at remote HOST
  ssl:HOST:PORT           SSL/TLS PORT at remote HOST
  unix:FILE               Unix domain socket named FILE
Passive JSON-RPC connection methods:
  ptcp:PORT[:IP]          listen to TCP PORT on IP
  pssl:PORT[:IP]          listen for SSL/TLS on PORT on IP
  punix:FILE              listen on Unix domain socket FILE
  pfd:FD                  listen on pre-opened file descriptor FD
PKI configuration (required to use SSL/TLS):
  -p, --private-key=FILE  file with private key
  -c, --certificate=FILE  file with certificate for private key
  -C, --ca-cert=FILE      file with peer CA certificate
  --bootstrap-ca-cert=FILE  file with peer CA certificate to read or create
SSL/TLS options:
  --ssl-protocols=PROTOS    range of SSL/TLS protocols to enable
  --ssl-ciphers=CIPHERS     list of SSL/TLS ciphers to enable

                          Mutually exclusive with the DATABASE,

  --no-chdir              do not chdir to '/'
  --pidfile[=FILE]        create pidfile (default: /run/openvswitch/ovsdb-server.pid)
  --overwrite-pidfile     with --pidfile, start even if already running

Logging options:
  -vSPEC, --verbose=SPEC   set logging levels
  -v, --verbose            set maximum verbosity level
  --log-file[=FILE]        enable logging to specified FILE
                           (default: /var/log/openvswitch/ovsdb-server.log)
  --syslog-method=(libc|unix:file|udp:ip:port)
                           specify how to send messages to syslog daemon
  --syslog-target=HOST:PORT  also send syslog msgs to HOST:PORT via UDP

Syncing options:
  --sync-from=SERVER      sync DATABASE from active SERVER and start in
                          backup mode (except with --active)
  --sync-exclude-tables=DB:TABLE,...
                          exclude the TABLE in DB from syncing
  --active                with --sync-from, start in active mode
