Each zone maintains a virtual console, /dev/console. Performing actions on the console is referred to as console mode. Console login to a zone is available when the zone is in the installed state. The zone console is closely analogous to a serial console on a system. Connections to the console persist across zone reboots. To understand how console mode differs from a login session such as telnet, see Remote Login.
The zone console is accessed by using the zlogin command with the -C option and the zonename. The zone does not have to be in the running state.
Processes inside the zone can open and write messages to the console. If the zlogin -C process exits, another process can then access the console.
