My CS education left out "System Virtual Machines" (as defined by 
Wikipedia: https://en.wikipedia.org/wiki/Virtual_machine). When I hear 
or read "VM", I think of "Process Virtual Machines" - which were always 
useful as intermediate targets during compilation and/or interpreters 
(p-code or the WAM for Prolog).

The job of the OS (as I understood it) was to manage the HW, and the 
first OS I used that effectively virtualized the CPU and memory was Unix 
on "worksations". MacOS and DOS just didn't compare anymore.

I can see the utility of System VMs on servers, but not something I'd 
use every day.
