【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%.更多还原

【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.更多还原
