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.

       • /run/libvirt/virtlogd-sock

       The sockets virtlogd will use.

       • /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 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) 8.0.0

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

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