Note > that I have no idea how to solve this one. for containers it's exactly the right behavior: group scheduling is really a 'super' container concept that allows the allocation of CPU time regardless of how a group uses it. The only additional control we might want is to allocate different amount of CPU time to different groups. (i.e. a concept vaguely similar to "nice levels", but at the group level - using a different and saner API than nice levels.) Nice levels are really only meaningful at the lowest level. for 'friendly users' it's perhaps not what we want - but those do not need to isolate themselves from each other anyway. > Thanks for working in this very interesting direction. seconded :) Ingo _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
