摘要

桌面虚拟化通常运行混合负载

且更注重交互式性能

现有的虚拟机调度算法无法很好适应这两个特点.本文提出了一种全时抢占CPU调度算法

通过灰盒技术探测虚拟机内部信息用于辅助虚拟机调度

并结合远程桌面的负载特性进行优化.评测表明

5台Windows XP虚拟机同时运行混合负载

优化后播放幻灯片的显示延迟降低了至少60%.

Abstract

Desktop virtualization usually runs mixed workload

and is more sensitive to the interactive performance.Current virtual machine scheduler cannot meet the two demands.This paper presents a full-time preemption CPU scheduler.It uses grey-box technology to inspect information inside virtual machine to support virtual machine scheduling

and considers the characteristics of remote desktop workload for optimization.The evaluation results show that when 5 Windows XP virtual machines running mixed workload concurrently

the display latency of slides presentation is reduced by at least 60% with our optimization.
