where DATABASE is a socket on which ovsdb-server is listening
      (default: "unix:/run/openvswitch/db.sock").

Active DATABASE 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
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
                            with TLSv1.2
  --ssl-ciphersuites=SUITES list of SSL/TLS ciphersuites to
                            enable with TLSv1.3 and later
  --ssl-server-name=NAME    server name for TLS Server Name
                            Indication (SNI)

Daemon options:
  --detach                run in background as daemon

  --no-chdir              do not chdir to '/'
  --pidfile[=FILE]        create pidfile (default: /run/openvswitch/ovs-vswitchd.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/ovs-vswitchd.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
