SYNOPSIS
========
``virtvboxd`` [*OPTION*]...
DESCRIPTION
===========
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.
DAEMON STARTUP MODES
====================
The ``virtvboxd`` 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/virtvboxd.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`` ``virtvboxd`` will reload its configuration.
FILES
=====
When run as *root*
------------------
* ``@SYSCONFDIR@/libvirt/virtvboxd.conf``
The default configuration file used by ``virtvboxd``, unless overridden on the
command line using the ``-f`` | ``--config`` option.
* ``@RUNSTATEDIR@/libvirt/virtvboxd-sock``
* ``@RUNSTATEDIR@/libvirt/virtvboxd-sock-ro``
* ``@RUNSTATEDIR@/libvirt/virtvboxd-admin-sock``
The sockets ``virtvboxd`` will use.
The TLS **Server** private key ``virtvboxd`` will use.
* ``@RUNSTATEDIR@/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``
EXAMPLES
========
To retrieve the version of ``virtvboxd``:
::
# virtvboxd --version
virtvboxd (libvirt) @VERSION@
To start ``virtvboxd``, instructing it to daemonize and create a PID file:
::
# virtvboxd -d
# ls -la @RUNSTATEDIR@/virtvboxd.pid
-rw-r--r-- 1 root root 6 Jul 9 02:40 @RUNSTATEDIR@/virtvboxd.pid
