These are called "virtual" because you + can run several virtual terminals (also called virtual consoles) on + one physical terminal. This is rather useful, for example one + virtual terminal can collect system messages and warnings, another + one can be used for a text-mode user session, and a third could run + an X session, all in parallel. Switching between virtual terminals + is done with certain key combinations, usually Alt-<function key>. + + The setterm command ("man setterm") can be used to change the + properties (such as colors or beeping) of a virtual terminal. The + man page console_codes(4) ("man console_codes") contains the special + character sequences that can be used to change those properties + directly.

You can change + that with a kernel command line option such as "console=tty3" which + would use the third virtual terminal as system console.
