lxc-console - Launch a console for the specified container
lxc-console -n name [ -e escape character ] [ -t ttynum ]
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>.
-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 '^b'. -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.
These options are common to most of lxc commands. -?, -h, --help Print a longer usage message than normal. --usage Give the usage message -q, --quiet mute on -P, --lxcpath=PATH Use an alternate container path. The default is /usr/local/var/lib/lxc. -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, ERROR, NOTICE, INFO, DEBUG, TRACE. 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. --rcfile=FILE Specify the configuration file to configure the virtualization and isolation functionalities for the container. 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). --version Show the version number.
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.
