In this work, we analyze the impact that live VM migration has on virtualized data centers in terms of performance and power consumption. We present a metric that captures system efficiency in terms of VM resource usage. This metric is used to create a resource efficiency manager (REM) framework that issues live VM migrations to enhance the efficiency of system resources. We compare our framework to other commercially available solutions and show that we can improve performance up to 9% while providing a better overall power/performance solution.
