NAME
       virtlogd - libvirt log management daemon

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

       /var/run/libvirt/virtlogd-sock
	   The sockets libvirtd will use.

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

   When run as non-root.
       $XDG_CONFIG_HOME/virtlogd.conf
	   The default configuration file used by libvirtd, unless overridden
	   on the command line using the -f|--config option.

       $XDG_RUNTIME_DIR/libvirt/virtlogd-sock
	   The socket libvirtd 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, libvirtd will use
       $HOME/.config
       If $XDG_RUNTIME_DIR is not set in your environment, libvirtd will use
       $HOME/.cache

EXAMPLES
       To retrieve the version of virtlogd:

	# virtlogd --version
	virtlogd (libvirt) 1.1.1
	#

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

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