NAME
       virtnetworkd - libvirt virtual network management daemon

SYNOPSIS
       virtnetworkd [OPTION]...

DESCRIPTION
       The virtnetworkd program is a server side daemon component of the
       libvirt virtualization management system.

       It is one of a collection of modular daemons that replace functionality
       previously provided by the monolithic libvirtd daemon.

       This daemon runs on virtualization hosts to provide management for
       virtual networks.

       The virtnetworkd daemon only listens for requests on a local Unix
       domain socket. Remote access via TLS/TCP and backwards compatibility
       with legacy clients expecting libvirtd is provided by the virtproxyd
       daemon.

       Restarting virtnetworkd does not interrupt running guests. Guests
       continue to operate and changes in their state will generally be picked
       up automatically during startup. None the less it is recommended to
       avoid restarting with running guests whenever practical.

DAEMON STARTUP MODES
       The virtnetworkd daemon is capable of starting in two modes.

   Socket activation mode
       On hosts with systemd it is started in socket activation mode and it
       will rely on systemd to create and listen on the UNIX sockets and pass
       them as pre-opened file descriptors. In this mode most of the socket
       related config options in /etc/libvirt/virtnetworkd.conf will no longer
       have any effect.

   Traditional service mode
       On hosts without systemd, it will create and listen on UNIX sockets
       itself.

OPTIONS
       -h, --help

       Display command line help usage then exit.

       -d, --daemon

       Run as a daemon & write PID file.

       -f, --config *FILE*

       Use this configuration file, overriding the default value.

       -p, --pid-file *FILE*

       Use this name for the PID file, overriding the default value.

       -t, --timeout *SECONDS*

       Exit after timeout period (in seconds), provided there are no client
       connections.

       -v, --verbose

       Enable output of verbose messages.

       --version

       Display version information then exit.

SIGNALS
       On receipt of SIGHUP virtnetworkd will reload its configuration.

FILES
   When run as root

       o /etc/libvirt/virtnetworkd.conf

       The default configuration file used by virtnetworkd, unless overridden
       on the command line using the -f | --config option.

       o /run/libvirt/virtnetworkd-sock

       o /run/libvirt/virtnetworkd-sock-ro

       o /run/libvirt/virtnetworkd-admin-sock

       The sockets virtnetworkd will use.

       The TLS Server private key virtnetworkd will use.

       o /run/virtnetworkd.pid

       The PID file to use, unless overridden by the -p | --pid-file option.

   When run as non-root

       o $XDG_CONFIG_HOME/libvirt/virtnetworkd.conf

       The default configuration file used by virtnetworkd, unless overridden
       on the command line using the -f``|--config`` option.

       o $XDG_RUNTIME_DIR/libvirt/virtnetworkd-sock

       o $XDG_RUNTIME_DIR/libvirt/virtnetworkd-admin-sock

       The sockets virtnetworkd will use.

       o $XDG_RUNTIME_DIR/libvirt/virtnetworkd.pid

       The PID file to use, unless overridden by the -p``|--pid-file`` option.

       If $XDG_CONFIG_HOME is not set in your environment, virtnetworkd will
       use $HOME/.config

       If $XDG_RUNTIME_DIR is not set in your environment, virtnetworkd will
       use $HOME/.cache

EXAMPLES
       To retrieve the version of virtnetworkd:

          # virtnetworkd --version
          virtnetworkd (libvirt) 11.2.0

       To start virtnetworkd, instructing it to daemonize and create a PID
       file:

          # virtnetworkd -d
          # ls -la /run/virtnetworkd.pid
          -rw-r--r-- 1 root root 6 Jul  9 02:40 /run/virtnetworkd.pid
