Virtualization technology has been gaining acceptance in the scientific community due to its overall flexibility in running HPC applications. It has been reported that a specific class of applications is better suited to a particular type of virtualization scheme or implementation. For example, Xen has been shown to perform with little overhead for compute-bound applications. Such a paper, although useful, does not allow the authors to generalize conclusions beyond the performance analysis of that application which is explicitly executed.
