Interview with Linux-VServer Project Leader Herbert Pötzl

[ Thanks to Scott
for this link. ]

ML: One of the unique features (in my mind) of
Linux-VServer is unification. Could you please provide a brief
description of what unification is and list any potential benefits
or drawbacks?

Bertl: I think there are quite a number of
‘unique’ features in Linux-VServer, unification is only a small
puzzle piece to achieve high density and efficient resource
usage… but to get back to your question:

“Typical hosting scenarios have a large number of quite similar
guests–think fifty times Debian and forty times Fedora–so it can
be assumed that they will share the very same files, like libraries
and executables and only differ in configuration and ‘user data’.
Typically, those common files will not only take up a lot of disk
space, each file will also consume a certain amount of memory (for
caching and mapping)…”
