Abstract:
In this paper we assess the impact of virtualization in both performance-oriented environments, like high performance computing facilities, and throughput-oriented systems, like data processing centers, e.g., for web search and data serving. In particular, our work-in-progress analyzes the power consumption required to dynamically migrate virtual machines at runtime,
a technique that is crucial to consolidate underutilized servers, reducing energy costs while maintaining service level agreements. Preliminary experimental results are reported for two different applications, using the KVM virtualization solution for Linux, on an Intel Xeon-based cluster.
