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/libvirt/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/libvirt/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
        #
