Let's take an example where I have 1 group that I wish to guarantee a 20% share of the cpu, and anther 8 groups with no limits or guarantees. One way to achieve the guarantee is to hard limit each of the 8 other groups to 10%; the sum total of the limits is 80%, leaving 20% for the guarantee group. The downside is the arbitrary limit imposed on the other groups. Another way is to place the 8 groups in a container group, and limit that to 80%. But that doesn't work if I want to provide guarantees to several groups. -- error compiling committee.c: too many arguments to function _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
