OK, so based on what you're saying (and after reading a bit at openstack.org),
I'm now thinking that openstack would run "natively" (basically as an
operating system) in a VM and then your instance(s) would run on top of
that (as a "node"), right? And there is a concept of a "management network"
that is private -- so you could have an outward-facing node running the
latest linux distro and acting as a bastion host for a "legacy node" (that
is otherwise unreachable from the outside world -- save for any connections
initiated by the legacy node). And nodes could be anywhere in the
virtual/physical world, including all coincident on the same VM?
