The software log records and audit are the vital parts of the software fault-tolerant,but the existing log file system lacks adequate information for supporting security audit and fault recovery.To solve the problem,VDSL（Virtual Distributed Software Log management system）uses the virtualization technology to encapsulate the SAAS execution environment.VDSL overcomes the shortcomings of the traditional log management system including poor isolation,low resource utilization.VDSL records the software log in every virtual node with instrumentation technology by sending the log to fault server.The experiments show that the VDSL system can complete the software log management function in distributed software virtualization environment for supporting log audit and fault recovery,achieving the validity,reliability and fault tolerance of software log function. 软件容错 日志记录 日志同步 动态二进制翻译 分布式软件 software fault-tolerant log record log synchronization dynamic binary translation distributed software 10.14188/j.1671-8836.2014.05.004 TP393.01 国家高技术研究发展计划（973）项目（2012AA012600） 2014-05-01 2021-04-01 5 60
