Modeling Virtualized Environments in Simalytic Models by Computing Missing Service Demand Parameters

Dr. Tim R. Norton Simalytic Solutions, LLC CMG 2009 Paper 9103 Session 601 System Virtualization allows multiple O/S images to execute on a single physical host computer. Measuring the host resource usage is straightforward and the necessary tools are included with most virtualization environments. However, complexities introduced by the different virtualization techniques create problems with measurements within the guests, resulting in missing model parameters. This paper shows how to use the Menascé technique that computes missing parameters with the Simalytic Modeling technique to predict application performance more effectively in virtualization environments.
