i think vcontext.

over the years people have asked how to scale linux-vserver to hundreds of
vservers and herbert has mentioned running just the needed application
(like you are requesting), and i think he mentioned vcontext, but i can't
currently find any of the emails in the mailing list archive.

yeah, that's a pretty complex example to start with.

an alternative, so as to not stray too far from the beaten path (usual use
case of "vserver <name> start" with plethora of online examples), is to
create a regular vserver and strip it down as people have done through the
ages for embedded or appliance usage (ie delete everything but your
application, its dependencies, and an init script).

or wrong enough that somebody will speak up and correct me. ;-)
