Energy-aware Processor Management for Virtual Machines

Abstract

Over the past years, virtualization technology has regained considerable attention in the design of computer systems. Virtual machines establish a development path for incorporating new functionality (server consolidation, transparent migration, secure computing, etc.) into a system that simultaneously retains compatibility to existing OSes and applications. At the very same time, with the ever increasing power density and dissipation of modern servers, energy management is becoming more and more a key concern in the design of operating systems. Research has proposed several approaches to OSdirected control over a computer’s energy consumption, including user- and service-centric management schemes [1,5]. However, all existing approaches assume full control over and full knowledge of the underlying machin
