       virt-login-shell - tool to execute a shell within a container matching
       the users name

       virt-login-shell [OPTION]

       The virt-login-shell program is a setuid shell that is used to join an
       LXC container that matches the user's name.  If the container is not
       running, virt-login-shell will attempt to start the container.  virt-
       login-shell is not allowed to be run by root.  Normal users will get
       added to a container that matches their username, if it exists, and
       they are configured in /etc/libvirt/virt-login-shell.conf.

       The basic structure of most virt-login-shell usage is:


       -c CMD
           Instruct the shell to run CMD instead of presenting an interactive
           shell prompt.

       -h, --help
           Display command line help usage then exit.

       -V, --version
           Display version information then exit.

       By default, virt-login-shell will execute the /bin/sh program for the
       user.  You can modify this behaviour by defining the shell variable in

       eg.  shell = [ "/bin/bash" ]

       If the 'auto_shell' config option is set then it will attempt to
       automatically detect the shell from /etc/password inside the container.
       This should only be done if the container has a separate /etc directory
       from the host, otherwise it will end up recursively invoking virt-

       eg. auto_shell = 1

       By default no users are allowed to use virt-login-shell, if you want to
       allow certain users to use virt-login-shell, you need to modify the
       allowed_users variable in /etc/libvirt/virt-login-shell.conf.

       eg. allowed_users = [ "tom", "dick", "harry" ]

       virt-login-shell normally returns the exit status of the command it
       executed. If the command was killed by a signal, but that signal is not
       fatal to virt-login-shell, then it returns the signal number plus 128.

       Exit status generated by virt-login-shell itself:

       0 An option was used to learn more about this binary.
       125 Generic error before attempting execution of the configured shell;
       for example, if libvirtd is not running.
       126 The configured shell exists but could not be executed.
       127 The configured shell could not be found.
