Oh that is cool! Somehow I imagined that virtualization is more of a "modern" concept, but clearly that is naive thinking.

History edit
A form of virtualization was first demonstrated with IBM's CP-40 research system in 1967, then distributed via open source in CP/CMS in 1967–1972, and re-implemented in IBM's VM family from 1972 to the present. Each CP/CMS user was provided a simulated, stand-alone computer.

Sometimes it feels like we don't have any actual innovation in CS anymore and it's all from pre 2000s and only made mainstream starting then.
