As more and more VMs run simultaneously on a single platform, the platform shared resources(eg. LLC, Memory bandwidth) become a key contention between VMs. The increasing resource contention and lack of control for it result in poor determinism and QoS for each individual VM. This is, however, a key requirement for cloud infrastructure, data center apps and communications workloads(NFV/SDN).This talk describes the QoS challenges for Server Virtualization. It then introduces Intel platform shared resource monitoring/control technologies exist on recent Intel server platforms and examine how QoS can be achieved with them. After that it outlines the implementation in recent Xen, such as CMT,MBM and CAT, etc. Particularly, it focuses on how these technologies can be used to improve QoS in modern data centers and cloud platforms. Finally, it introduces the potential future work in this area.
