摘要:

基于虚拟机技术的服务器整合可以提高系统能效,但虚拟化机制的隔离效应为功耗管理带来新的挑战。本文面向虚拟化计算环境,提出虚拟机内外相结合的两级功耗管理模型;设计了功耗行为多级监控框架;提出功耗管理机制虚拟化映射并设计了满足虚设备性能需求的物理速率映射算法;实现了用户透明的功耗管理虚拟化方案。实验表明,本文提出的功耗管理虚拟化技术支持用户透明的功耗管理,对系统性能的影响不足1%,满足高端计算需求。

Abstract:

Server consolidation based on virtual machines is employed to improve the system utilization and energy efficiency.However, the isolation effect of virtualization imposes a challenge to power management.A twolevel model,i.e.inside and outside virtual machine,is proposed for transparent power management in virtual machine environments.A multilevel power behavior statistic framework is introduced to support the power profiling of virtual devices,the virtual machine and the host.Power management mechanisms are virtualized and a dynamic speed scaling algorithm is proposed to map the power management actions between virtual devices and physical devices.The experiments demonstrate that our transparent virtualization solution of power management has a negligible decline of the system performance,which is less than 1%.
