SYNOPSIS
|
|
========
|
|
|
|
``virtlogd`` [*OPTION*]...
|
|
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
The ``virtlogd`` program is a server side daemon component of the libvirt
|
|
virtualization management system that is used to manage logs from virtual
|
|
machine consoles.
|
|
|
|
This daemon is not used directly by libvirt client applications, rather it
|
|
is called on their behalf by ``libvirtd``. By maintaining the logs in a
|
|
standalone daemon, the main libvirtd daemon can be restarted without risk
|
|
of losing logs. The ``virtlogd`` daemon has the ability to re-exec()
|
|
itself upon receiving SIGUSR1, to allow live upgrades without downtime.
|
|
|
|
The ``virtlogd`` daemon listens for requests on a local Unix domain socket.
|
|
|
|
|
|
OPTIONS
|
|
=======
|
|
|
|
``-h``, ``--help``
|
|
|
|
Display command line help usage then exit.
|
|
|
|
``-d``, ``--daemon``
|
|
|
|
Run as a daemon and write PID file.
|
|
|
|
``-f``, ``--config`` *FILE*
|
|
|
|
Use this configuration file, overriding the default value.
|
|
|
|
``-t``, ``--timeout`` *SECONDS*
|
|
|
|
Automatically shutdown after *SECONDS* have elapsed with
|
|
no active console log.
|
|
|
|
``-p``, ``--pid-file`` *FILE*
|
|
|
|
Use this name for the PID file, overriding the default value.
|
|
|
|
``-v``, ``--verbose``
|
|
|
|
Enable output of verbose messages.
|
|
|
|
``-V``, ``--version``
|
|
|
|
Display version information then exit.
|
|
|
|
|
|
SIGNALS
|
|
=======
|
|
|
|
On receipt of ``SIGUSR1``, ``virtlogd`` will re-exec() its binary, while
|
|
maintaining all current logs and clients. This allows for live
|
|
upgrades of the ``virtlogd`` service.
|
|
|
|
|
|
FILES
|
|
=====
|
|
|
|
When run as *root*
|
|
------------------
|
|
|
|
* ``@SYSCONFDIR@/libvirt/virtlogd.conf``
|
|
|
|
The default configuration file used by ``virtlogd``, unless overridden on the
|
|
command line using the ``-f`` | ``--config`` option.
|
|
|
|
* ``@RUNSTATEDIR@/libvirt/virtlogd-sock``
|
|
|
|
The sockets ``virtlogd`` will use.
|
|
|
|
* ``@RUNSTATEDIR@/virtlogd.pid``
|
|
|
|
The PID file to use, unless overridden by the ``-p`` | ``--pid-file`` option.
|
|
|
|
When run as *non-root*
|
|
----------------------
|
|
|
|
* ``$XDG_CONFIG_HOME/libvirt/virtlogd.conf``
|
|
|
|
The default configuration file used by ``virtlogd``, unless overridden on the
|
|
command line using the ``-f`` | ``--config`` option.
|
|
|
|
* ``$XDG_RUNTIME_DIR/libvirt/virtlogd-sock``
|
|
|
|
The socket ``virtlogd`` will use.
|
|
|
|
* ``$XDG_RUNTIME_DIR/libvirt/virtlogd.pid``
|
|
|
|
The PID file to use, unless overridden by the ``-p`` | ``--pid-file`` option.
|
|
|
|
If ``$XDG_CONFIG_HOME`` is not set in your environment, ``virtlogd`` will use
|
|
``$HOME/.config``
|
|
|
|
If ``$XDG_RUNTIME_DIR`` is not set in your environment, ``virtlogd`` will use
|
|
``$HOME/.cache``
|
|
|
|
|
|
EXAMPLES
|
|
========
|
|
|
|
To retrieve the version of ``virtlogd``:
|
|
|
|
::
|
|
|
|
# virtlogd --version
|
|
virtlogd (libvirt) @VERSION@
|
|
|
|
To start ``virtlogd``, instructing it to daemonize and create a PID file:
|
|
|
|
::
|
|
|
|
# virtlogd -d
|
|
# ls -la @RUNSTATEDIR@/virtlogd.pid
|
|
-rw-r--r-- 1 root root 6 Jul 9 02:40 @RUNSTATEDIR@/virtlogd.pid
