摘　　要：硬件计算能力的极大提高重新激发了人们研究虚拟机软件的热情。XEN虚拟机是目前业界广泛看好的一款开源的虚拟机管理软件,它具有良好的体系结构和优越的性能。随着虚拟机的应用,会出现新的安全问题。介绍了XEN虚拟机的系统结构,重点探讨了基于Intel VT-x的硬件虚拟技术,从处理器管理、内存管理和设备管理三个方面阐释了XEN虚拟机的基本工作原理及其实现的关键技术;在此基础之上,探讨了XEN虚拟机的安全问题并提出了一些安全措施。The great improvement of the hardware computing capability has stimulated people＇s enthusiasm to study virtual machine monitor again. XEN is an open-source virtualization machine monitor, whose future is widespread optimistic by the industry. It has a good system architecture and surprising performance. Companying With the application of the virtual machine, there are some new security challenges to be proposed. The hardware virtualization technology was interpreted based on Intel＇s VT-x technology and the essences of XEN from the prospects of processor, memory and device managements were analyzed, Based on the above analysis, the security of XEN was discussed and some solution schema against security flaws was proposed.
