Measuring and modeling the performance of the Xen VMM

Server virtualization technology provides an alternative for server consolidation by creating a set of logical resources that share underlying physical resources. Xen virtual machine monitor, a popular virtualization solution in Linux world, supports execution of multiple guest operating systems with unprecedented levels of performance and resource isolation. Performance modeling of virtual servers faces challenges of obtaining meaningful measures as the operating system deals with virtual resources. This paper presents a practical approach for measuring and modeling the performance of Xen.
