ICS2008-05-01: Accuracy and Responsiveness of CPU Sharing Using Xen's Cap Values - D. Schanzenbach, H. Casanova

Abstract: The accuracy and responsiveness of the Xen CPU Scheduler is evaluated using the "cap value" mechanism provided by Xen. The goal of the evaluation is to determine whether state-of-the-art virtualization technology, and in particular Xen, enables CPU sharing that is sufficiently accurate and responsive for the purpose of enabling "flexible resource allocations" in virtualized cluster environments.
