Ohhhhh... Now I see :) CKRM is using too much heavy framework, with hierarchical settings and so on, but little practical things. Our approach is totally different, we make it simple and straitforward and all resource management features are compile-time configurable. > Considering we tend to mostly have only per-process resource management, > low level virtualisation seems like a much better place to do this. it depends. if you want trully secure environment in Linux, resource management is a MUST. Also, per-process management is not natural from user POV. Thanks, Kirill
