摘要： 为提高PC系统的可管理性和安全性，提出一种轻量级虚拟机软件技术——LVMM。定义活跃用户域，可直接访问除磁盘和网络之外的物理设备，以及虚拟磁盘和虚拟网络设备。保证在保持PC使用模式基本不变的前提下，可在同一平台上同时运行多个用户虚拟系统，且支持独立于用户操作系统的资源访问控制。经测试，LVMM原型系统具有较小的整体虚拟化开销。

Abstract: This paper presents a light weight virtual machine monitor——LVMM for improving the manageability and security of PCs. Compared with other virtual machine system, LVMM defines the active user domain which directly accesses the hardware devices except the physical disk and network devices. It accesses the virtual disk and virtual network card devices provided by the service domain. The user mode and experience of common PC users are kept unchanged while running several user domains on the LVMM platform simultaneously. The monitoring and access controlling of system resource in LVMM is independent of the user OS. Test result shows the prototype of the light weight virtual machine monitor has a little integral virtualization overhead.

Key words: virtual machine monitor, service deployment, virtualization
