VIRTNETWORKD(8) Virtualization Support VIRTNETWORKD(8) 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 automati- cally 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 con- nections. -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 * /usr/local/etc/libvirt/virtnetworkd.conf The default configuration file used by virtnetworkd, unless overridden on the command line using the -f | --config option. * /var/run/libvirt/virtnetworkd-sock * /var/run/libvirt/virtnetworkd-sock-ro * /var/run/libvirt/virtnetworkd-admin-sock The sockets virtnetworkd will use. The TLS Server private key virtnetworkd will use. * /var/run/virtnetworkd.pid The PID file to use, unless overridden by the -p | --pid-file option. When run as non-root * $XDG_CONFIG_HOME/libvirt/virtnetworkd.conf The default configuration file used by virtnetworkd, unless overridden on the command line using the -f``|--config`` option. * $XDG_RUNTIME_DIR/libvirt/virtnetworkd-sock * $XDG_RUNTIME_DIR/libvirt/virtnetworkd-admin-sock The sockets virtnetworkd will use. * $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) 12.5.0 To start virtnetworkd, instructing it to daemonize and create a PID file: # virtnetworkd -d # ls -la /var/run/virtnetworkd.pid -rw-r--r-- 1 root root 6 Jul 9 02:40 /var/run/virtnetworkd.pid BUGS Please report all bugs you discover.
