VIRT-LOGIN-SHELL(1)

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

SYNOPSIS
virt-login-shell [OPTION]

DESCRIPTION
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:

  virt-login-shell

OPTIONS

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

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

CONFIG
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 /etc/libvirt/virt-login-shell.conf.

eg. shell = [ "/bin/ksh", "--login"]

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" ]

EXIT STATUS
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.
