I've vague recollections that these all originally used the VM from Mach which did have problems at first. I recall a more knowledgeable friend complaining about FreeBSD VM in 1994 or so. I think the latter two use UVM and FreeBSD improved their Mach one (which has a SunOS kvmish API anyway). I've not seen complaints about modern BSD.

Everything else seems like a mess to me.

That may have been true in the la= te 80s and even early 90s but I'd have thought FreeBSD, NetBSD and Open= BSD would have useable VMs by now.
