中文摘要: Xen硬件虚拟化(HVM)是运行于Xen Hypervisor上, 无需修改客户操作系统内核便可实现虚拟化的技术. 但Xen HVM在提升用户体验的同时, 也造成了VMM对客户机的干涉和理解程度的降低, 丧失了进程粒度级别的管理能力. 鉴于此, 提出了一种针对Xen HVM客户机的轻量级进程追踪技术原型Xen HPT. 借助VMM掌握的客户机ESP寄存器信息, 从客户机外部隐式捕获其实时进程信息. 实验证明, 该技术是一种追踪客户机进程的有效方法.
Abstract:Xen Hardware-Assisted Virtualization(HVM) is a service that one can run a virtual machine which is a unmodified OS on Xen Hypervisor. HVM causes a loss of management of the process granularity for the reason of VMM's lack of interference and understanding of the guest OS. This paper presents a lightweight process trace method for Xen HVM named Xen HPT. With the assistance of guest OS register information (mainly the ESP) collected by VMM, Xen HPT can implicitly capture the real-time process information of target guest OS outside on Domain0 with little effect on guest OS.Xen HPT has been tested by Linux guest OS and result shows that the method is effective.
