Noisy Neighbor Strategy

Registered by Zhai, Edwin on 2016-11-15

L3 cache is critical and limit system level resource shared by all apps or VMs on one node. If one VM occupies most of L3 cache, other VMs on the node likely starve without enough L3 cache thus poor performance. This BP adds a new strategy to detect then migrate such cache greedy VM based on some new cache/memory metrics.
