+
+SYNOPSIS
+========
+
+``virtqemud`` [*OPTION*]...
+
+
+DESCRIPTION
+===========
+
+The ``virtqemud`` 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 QEMU virtual
+machines.
+
+The ``virtqemud`` daemon only listens for requests on a local Unix domain
+socket. Remote off-host access and backwards compatibility with legacy
+clients expecting ``libvirtd`` is provided by the ``virtproxy`` daemon.
+
+Restarting ``virtqemud`` 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.
+
+
+SYSTEM SOCKET ACTIVATION
+========================
+
+The ``virtqemud`` daemon is capable of starting in two modes.
+
+In the traditional mode, it will create and listen on UNIX sockets itself.
+
+In socket activation mode, 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/virtqemud.conf`` will no longer have any effect.
+
+Socket activation mode is generally the default when running on a host
+OS that uses systemd. To revert to the traditional mode, all the socket
+unit files must be masked:
+
+::
+
+   $ systemctl mask virtqemud.socket virtqemud-ro.socket \
+      virtqemud-admin.socket
+
+
+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 neither any client
+connections nor any running domains.
+
+``-v``, ``--verbose``
+
+Enable output of verbose messages.
+
+``--version``
+
+Display version information then exit.
+
+
+SIGNALS
+=======
+
+On receipt of ``SIGHUP`` ``virtqemud`` will reload its configuration.
+
+
+FILES
+=====
+
+When run as *root*
+------------------
+
+* ``@SYSCONFDIR@/libvirt/virtqemud.conf``
+
+The default configuration file used by ``virtqemud``, unless overridden on the
+command line using the ``-f`` | ``--config`` option.
+
+* ``@RUNSTATEDIR@/libvirt/virtqemud-sock``
+* ``@RUNSTATEDIR@/libvirt/virtqemud-sock-ro``
+* ``@RUNSTATEDIR@/libvirt/virtqemud-admin-sock``
+
+The sockets ``virtqemud`` will use.
+
+The TLS **Server** private key ``virtqemud`` will use.
+
+* ``@RUNSTATEDIR@/virtqemud.pid``
+
+The PID file to use, unless overridden by the ``-p`` | ``--pid-file`` option.
+
+
+When run as *non-root*
+----------------------
+
+* ``$XDG_CONFIG_HOME/libvirt/virtqemud.conf``
+
+The default configuration file used by ``virtqemud``, unless overridden on the
+command line using the ``-f``|``--config`` option.
+
+* ``$XDG_RUNTIME_DIR/libvirt/virtqemud-sock``
+* ``$XDG_RUNTIME_DIR/libvirt/virtqemud-admin-sock``
+
+The sockets ``virtqemud`` will use.
+
+* ``$XDG_RUNTIME_DIR/libvirt/virtqemud.pid``
+
+The PID file to use, unless overridden by the ``-p``|``--pid-file`` option.
+
+
+If ``$XDG_CONFIG_HOME`` is not set in your environment, ``virtqemud`` will use
+``$HOME/.config``
+
+If ``$XDG_RUNTIME_DIR`` is not set in your environment, ``virtqemud`` will use
+``$HOME/.cache``
+
+
+EXAMPLES
+========
+
+To retrieve the version of ``virtqemud``:
+
+::
+
+  # virtqemud --version
+  virtqemud (libvirt) @VERSION@
+
+
+To start ``virtqemud``, instructing it to daemonize and create a PID file:
+
+::
+
+  # virtqemud -d
+  # ls -la @RUNSTATEDIR@/virtqemud.pid
+  -rw-r--r-- 1 root root 6 Jul  9 02:40 @RUNSTATEDIR@/virtqemud.pid
