virtvboxd - libvirt VirtualBox management daemon

virtvboxd [OPTION]...

The virtvboxd 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 VirtualBox virtual machines.

The virtvboxd 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 virtvboxd does not interrupt running guests. Guests continue to operate and changes in their state will generally be picked up automatically during startup.

The virtvboxd daemon is capable of starting in two modes.

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/virtvboxd.conf will no longer have any effect.

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

-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.

On receipt of SIGHUP virtvboxd will reload its configuration.

When run as root

•
/etc/libvirt/virtvboxd.conf

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

  • /run/libvirt/virtvboxd-sock
  • /run/libvirt/virtvboxd-sock-ro
  • /run/libvirt/virtvboxd-admin-sock

The sockets virtvboxd will use.

The TLS Server private key virtvboxd will use.

•
/run/virtvboxd.pid

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

When run as non-root

•
$XDG_CONFIG_HOME/libvirt/virtvboxd.conf

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

  • $XDG_RUNTIME_DIR/libvirt/virtvboxd-sock
  • $XDG_RUNTIME_DIR/libvirt/virtvboxd-admin-sock

The sockets virtvboxd will use.

•
$XDG_RUNTIME_DIR/libvirt/virtvboxd.pid

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

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

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

To retrieve the version of virtvboxd:

# virtvboxd --version
virtvboxd (libvirt) 10.3.0

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

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