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¶
-c CMDInstruct 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.
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. e.g.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-login-shell. e.g.
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. e.g.
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.
