NAME

       libvirtd - libvirtd management daemon

SYNOPSIS

       libvirtd [OPTION]...

DESCRIPTION

       The libvirtd program is the server side daemon component of the libvirt virtualization
       management system.

       This daemon runs on host servers and performs required management tasks for virtualized
       guests.  This includes activities such as starting, stopping and migrating guests between
       host servers, configuring and manipulating networking, and managing storage for use by
       guests.

       The libvirt client libraries and utilities connect to this daemon to issue tasks and
       collect information about the configuration and resources of the host system and guests.

       By default, the libvirtd daemon listens for requests on a local Unix domain socket.  Using
       the -l|--listen command line option, the libvirtd daemon can be instructed to additionally
       listen on a TCP/IP socket.  The TCP/IP socket to use is defined in the libvirtd
       configuration file.

       Restarting libvirtd does not impact running guests.  Guests continue to operate and will
       be picked up automatically if their XML configuration has been defined.  Any guests whose
       XML configuration has not been defined will be lost from the configuration.

           Listen for TCP/IP connections.

       -p, --pid-file FILE
           Use this name for the PID file, overriding the default value.

       -t, --timeout SECONDS

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

       /etc/pki/CA/cacert.pem
           The TLS Certificate Authority certificate libvirtd will use.

       /etc/pki/libvirt/servercert.pem
           The TLS Server certificate libvirtd will use.

       /etc/pki/libvirt/private/serverkey.pem
           The TLS Server private key libvirtd will use.

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

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

       $XDG_RUNTIME_DIR/libvirt/libvirt-sock
           The socket libvirtd will use.

       $HOME/.pki/libvirt/cacert.pem
           The TLS Certificate Authority certificate libvirtd will use.

       $HOME/.pki/libvirt/servercert.pem
           The TLS Server certificate libvirtd will use.

       $HOME/.pki/libvirt/serverkey.pem
           The TLS Server private key libvirtd will use.

       $XDG_RUNTIME_DIR/libvirt/libvirtd.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 libvirtd:

        # libvirtd --version
        libvirtd (libvirt) 0.8.2

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

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