Most operating systems concepts[2] are much older than people think.
The topic for my talk next week. Unix had virtualization in 74. The

Unix port ran under OS/360's VM in 78.
What do you mean by "Unix had virtualization"?
I mean that 4th edition UNIX ran under a hypervisor in MERT in 74 as a

Come to think of it, what do you mean by
"OS/360's VM"?
IBM's standard VM/360. Sorry for the confusion.
