I just thought I'd weigh in on this. As far as our usage pattern is concerned, guarantees cannot be met via limits. I want to give "x" cpu to container X, "y" cpu to container Y, and "z" cpu to container Z. If these are percentages, x+y+z must be less than 100. However, if Y does not use its share of the cpu, I would like the leftover cpu time to be made available to X and Z, in a ratio based on their allocated weights. With limits, I don't see how I can get the ability for containers to make opportunistic use of cpu that becomes available. I can see that with things like memory this could become tricky (How do you free up memory that was allocated to X when Y decides that it really wants it after all?) but for CPU I think it's a valid scenario.
