Remote off-host access and backwards compatibility with legacy +clients expecting ``libvirtd`` is provided by the ``virtproxy`` daemon. + +Restarting ``virtvzd`` 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 ``virtvzd`` 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/virtvzd.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 virtvzd.socket virtvzd-ro.socket \ + virtvzd-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`` ``virtvzd`` will reload its configuration. + + +FILES +===== + +When run as *root* +------------------ + +* ``@SYSCONFDIR(a)/libvirt/virtvzd.conf`` + +The default configuration file used by ``virtvzd``, unless overridden on the +command line using the ``-f`` | ``--config`` option. + +* ``@RUNSTATEDIR@/libvirt/virtvzd-sock`` +* ``@RUNSTATEDIR@/libvirt/virtvzd-sock-ro`` +* ``@RUNSTATEDIR@/libvirt/virtvzd-admin-sock`` + +The sockets ``virtvzd`` will use. + +The TLS **Server** private key ``virtvzd`` will use. + +* ``@RUNSTATEDIR(a)/virtvzd.pid`` + +The PID file to use, unless overridden by the ``-p`` | ``--pid-file`` option. + + +When run as *non-root* +---------------------- + +* ``$XDG_CONFIG_HOME/libvirt/virtvzd.conf`` + +The default configuration file used by ``virtvzd``, unless overridden on the +command line using the ``-f``|``--config`` option. + +* ``$XDG_RUNTIME_DIR/libvirt/virtvzd-sock`` +* ``$XDG_RUNTIME_DIR/libvirt/virtvzd-admin-sock`` + +The sockets ``virtvzd`` will use. + +* ``$XDG_RUNTIME_DIR/libvirt/virtvzd.pid`` + +The PID file to use, unless overridden by the ``-p``|``--pid-file`` option. + + +If ``$XDG_CONFIG_HOME`` is not set in your environment, ``virtvzd`` will use +``$HOME/.config`` + +If ``$XDG_RUNTIME_DIR`` is not set in your environment, ``virtvzd`` will use +``$HOME/.cache`` + + +EXAMPLES +======== + +To retrieve the version of ``virtvzd``: + +:: + + # virtvzd --version + virtvzd (libvirt) @ + + +To start ``virtvzd``, instructing it to daemonize and create a PID file: + +:: + + # virtvzd -d + # ls -la @RUNSTATEDIR(a)/virtvzd.pid + -rw-r--r-- 1 root root 6 Jul 9 02:40 @RUNSTATEDIR(a)/virtvzd.pid + + +BUGS +==== + +Please report all bugs you discover.
