=head1 NAME
|
|
|
|
virt-login-shell - tool to execute a shell within a container matching the users name
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<virt-login-shell> [I<OPTION>]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<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
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over
|
|
|
|
=item B<-h, --help>
|
|
|
|
Display command line help usage then exit.
|
|
|
|
=item B<-V, --version>
|
|
|
|
Display version information then exit.
|
|
|
|
=back
|
|
|
|
=head1 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" ]
|
|
|
|
=head1 EXIT STATUS
|
|
|
|
B<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 B<virt-login-shell> itself:
|
|
|
|
=over 4
|
|
|
|
=item B<0> An option was used to learn more about this binary.
|
|
|
|
=item B<125> Generic error before attempting execution of the configured
|
|
shell; for example, if libvirtd is not running.
|
|
|
|
=item B<126> The configured shell exists but could not be executed.
|
|
|
|
=item B<127> The configured shell could not be found.
