NAME         top

       lxc-console - Launch a console for the specified container

SYNOPSIS         top

       lxc-console {-n name} [-e escape character] [-t ttynum]

DESCRIPTION         top

       If the tty service has been configured and is available for the
       container specified as parameter, this command will launch a
       console allowing to log on the container.

       The available tty are free slots taken by this command. That
       means if the container has four ttys available and the command
       has been launched four times each taking a different tty, the
       fifth command will fail because no console will be available.

       The command will connect to a tty. If the connection is lost or
       broken, the command can be launched again and regain the tty at
       the state it was before the disconnection.

       A ttynum of 0 may be given to attach to the container's
       /dev/console instead of its dev/tty<ttynum>.

       A keyboard escape sequence may be used to disconnect from the tty
       and quit lxc-console. The default escape sequence is <Ctrl+a q>.

OPTIONS         top

       -e, --escape escape character
              Specify the escape sequence prefix to use instead of <Ctrl
              a>.  This may be given as '^letter' or just 'letter'. For
              example to use <Ctrl+b q> as the escape sequence use -e

       -t, --tty ttynum
              Specify the tty number to connect to or 0 for the console.
              If not specified the next available tty number will be
              automatically chosen by the container.

COMMON OPTIONS         top

       These options are common to most of lxc commands.

       -?, -h, --help
              Print a longer usage message than normal.

              Give the usage message

       -q, --quiet
              mute on

       -P, --lxcpath=PATH
              Use an alternate container path. The default is

       -o, --logfile=FILE
              Output to an alternate log FILE. The default is no log.

       -l, --logpriority=LEVEL
              Set log priority to LEVEL. The default log priority is
              ERROR. Possible values are : FATAL, ALERT, CRIT, WARN,

              Note that this option is setting the priority of the
              events log in the alternate log file. It do not have
              effect on the ERROR events log on stderr.

       -n, --name=NAME
              Use container identifier NAME.  The container identifier
              format is an alphanumeric string.

              Specify the configuration file to configure the
              virtualization and isolation functionalities for the

              This configuration file if present will be used even if
              there is already a configuration file present in the
              previously created container (via lxc-create).

              Show the version number.

DIAGNOSTIC         top

       tty service denied
              No tty is available or there is not enough privilege to
              use the console. For example, the container belongs to
              user "foo" and "bar" is trying to open a console to it.
