Tom, no,
hub.org is using FreeBSD's
jail
facility, not VMware. Or rather, hub.org (annoyingly) doesn't say
much of anything at all about how they implement their "Virtual
Machine" service, but they do say they run FreeBSD on all their
servers, so I assume they must be using jail.
I don't know much about FreeBSD, but I've seen at least a few
knowledgeable folks comment on running AOLserver, OpenACS, etc. on it
here.
