Isn’t that in some kind of virtual machines?

I’m not familiar with those, the only “big” machines I worked with were Tandem.

Idk for sure, haven’t properly looked into it. Just read in passing that mainframes were doing this kind of thing for ages.

Wikipedia says regarding z/OS:

z/OS has a Workload Manager (WLM) and dispatcher which automatically manages numerous concurrently hosted units of work running in separate key-protected address spaces according to dynamically adjustable goals. This capability inherently supports multi-tenancy within a single operating system image. However, modern IBM mainframes also offer two additional levels of virtualization: LPARs and (optionally) z/VM.
