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¶
- •
- /etc/libvirt/virtnetworkd.conf
The default configuration file used by virtnetworkd, unless overridden on the command line using the -f | --config option.
- /run/libvirt/virtnetworkd-sock
- /run/libvirt/virtnetworkd-sock-ro
- /run/libvirt/virtnetworkd-admin-sock
The sockets virtnetworkd will use.
The TLS Server private key virtnetworkd will use.
- •
- /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) 10.0.0
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
