No, that's not true. AOS was basically 4.3BSD Tahoe plus NFS and it ran on
bare RT hardware. There was source code available to universities, though
as I recall some bits related to memory management were missing and
distributed as object files. I gathered, at the time, this was due to some
obscure intellectual property reasons. People later tried to Port e.g.
4.4BSD to aging RT hardware and found it challenging because the memory
subsystem was so different.
But anyway, there was no hypervisor involved.

Is it AOS stuff saved and available (including source code)
un some place on the Internet?
It was, and may still be in the afs heirarchy
I'm not going to say where, or how complete what was there is
I also seem to remember it still sat on top of an AIX microkernel
and didn't go down to bare metal.
