Do you have any documented requirements for container resource

Is there a minimum list of features and nice to have features for

as far as resource management is concerned?
Sure! You can check OpenVZ project (http://openvz.org) for example of
required resource management. BTW, I must agree with other people here
who noticed that per-process resource management is really useless and
hard to use :(
I totally agree.
I'll take a look at the references. I agree with you that it will be
useful to have resource management for a group of tasks.
For Resource Management to be useful it must depend on Resource Control.
Resource Control depends on per-process accounting. Per-process accounting,
when abstracted sufficiently, may enable higher level routines, preferrably
in userland, to extend functionality at will. All efforts should really go
into the successful abstraction of per-process accounting.
I couldn't agree more. All that's needed in the kernel is low level per
task control and statistics gathering. The rest can be done in user space.

PS I'm a big fan of the various efforts to improve the quality of the
performance statistics that are exported from the kernel and my only
wish is that they get together to create one comprehensive solution.
