Optimization of Credit-based Scheduler in Xen
Xiaoyong Li · Microcomputer applications · 2009
In virtualization machine monitor,a good scheduler can use the hardware resources effectively.Xen can schedule para-virtualized Guest OSes effectively,but it can't schedule full-virtualized Guest OSes effectively because Xen can't get enough information from full-virtualized OSes.This paper presents an optimal method for Credit-based scheduler which is used in Xen.We will run a feedback process which will report to Xen the workload of the current full-virtualization Guest OS which operates it,so that the hardware resources can be used more effectively.
