The big question is : are containers/RG allowed to use *upto* their limit always? In other words, will you typically setup limits such that sum of all limits = max resource capacity? If it is setup like that, then what you are considering as limit is actually guar no? If it wont be setup like that, then I dont see how one can provide QoS. -- Regards, vatsa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
