I won't comment on 'Compaq is usually junk', but:
1. VMS is a respected OS that exists for more than 20 years, and
(from the Jargon file)
"Many Unix fans generously concede that
VMS would probably be the hacker's favorite commercial OS if Unix
didn't exist; ..."
2. As I understand, OpenVMS is far from becoming open source, and
OPEN was added (about 10 years ago?) to compete against the 'openness'
of Unix vs. the 'closeness' of traditional proprietary OSes like
VMS and MVS (now OS/390, the OS of IBM's mainframe).

I think you are talking about 'Galaxy'. I never used it, but I don't
think it's real virtualization - it lets several OSes use the same
hardware, but (if I understand correctly) every CPU belongs to only
one OS instance at every point in time, and other hardware components
are also divided somehow between the OSes such that each one 'sees'
a part of the machine. It's more like the way you can run several
instances of Solaris on big SUN machines. No CPU runs two OSes
concurrently (a host and a guest).
Anyway, as someone else said, it's only on Alphas.
