linux-vserver is about sharing resources to improve
overall performance and resource usage, if you are looking
for something which does strict hardware/resource partitioning
maybe something like XEN would be the best choice ...
guaranteed CPU for example, is a question of book keeping
on the admin side ... when I have 10 vservers and allow
each a maximum of 20% cpu, you can expect each to get a
minimum of 10% (fair scheduling/TB-sched) that can be seen
as guarantee, but you do not configure it anywhere ...
this doesn't mean, that future kernel/userspace solutions
will not support those calculations/changes in a friendlier
PS: UML doesn't support this either, maybe FreeVPS does,
but actually I doubt that there is a difference to what
I described above ...
