摘　　要：对虚拟机系统故障插入工具所涉及的故障模型、插桩方式、触发机制和监控跟踪等进行研究.通过统计分析各种虚拟机系统的故障症状,给出虚拟机系统的典型故障模型(包括故障类型、故障位置、发生模型和持续时间等)及实现代码.在研究虚拟机系统架构和故障插入实现原理的基础上,采用软件模拟方法基于Xen系统设计一个故障插入工具——SFIVE,介绍相应的插桩方式、触发机制和监控机制.实验分析表明,SFIVE具有较高的虚拟机系统故障覆盖率,能够激活和监控与大部分虚拟机相关的插桩故障.The mechanism involved by fault injection tools for virtual machine system such as failure model, injection mode, trigging mechanism, monitor and trace was studied. The typical failure model （including fault type, fault location, occurrence mechanism and duration） and its implementation were proposed by statistically analyzing the fault symptoms occurring in various virtual machine systems. By investigating the architecture of virtual machine system and the principle of fault injection, a fault injection tool for Xen system using software simulation method was designed--software fault injector for virtualized environments （SFIVE）, and its injection mode, trigging mechanism, monitor and trace were introduced. Experimental results show that SFIVE has higher fault type coverage of virtual machine system, and can activate and monitor most of fault types related to virtual machine.
