Abstract: This paper studies the scheme of full system replay in virtualization infrastructure. A virtual machine based replay system （VMRS） is designed and implemented for para-virtualized device model. All the non-deterministic events occurred in the virtual machine are recorded at the hypervisor layer， and the system execution stream recurs during replay by event emulation. Experimental results show VMRS has good performance and scalability.

Key words: virtual machine（VM）, system replay, event emulation, non-deterministic event

摘要： 研究了虚拟化体系结构下全系统回放的方法，设计实现了基于半虚拟化设备模型的虚拟机回放系统VMRS（virtual machine based replay system）。通过在虚拟机管理器中记录虚拟机内发生的不确定性事件并在回放时模拟不确定性事件的发生，从而完整重现系统的执行流。实验表明系统具有良好的性能和可扩展性。
