Abstract

This paper shows an analysis of the Xen virtual machine monitor, describing Credit Scheduler internal structure. The main goal of this work is to change a Xen scheduler in order to improve the performance of the virtual machines that are running over Xen. We present the places in which it is possible to make some improvements in the Credit Scheduler. An analysis of the new Credit scheduler is presented and shows the improvements for the overall system.
