摘　　要：虚拟化对云计算的实现提供了一种有效的解决方法，云计算的基础支撑性技术都是基于虚拟化技术的，而虚拟机动态迁移技术是实现虚拟化的重点。该文以虚拟机动态迁移关键技术的优化作为研究的主要目标，对现有的虚拟机动态迁移框架进行了解析，改进了动态迁移机制和迁移算法，提出预测概率算法和内存压缩算法。通过实验与比较分析，证明该改进框架和算法在虚拟机动态迁移上减少了数据传输量，缩短宕机时间，提高了虚拟机动态迁移性能。Virtualizationprovides an effective solution to the implementation of cloud computing. The basic support- ing technology of cloud computing is based on virtualization technology;but the virtual machine live migration is the key to realize virtualization technology. Based on the virtual machine live migration key technology optimization as the main target of research, the existing virtual machine live migration framework for parsing, and migration algo- rithm improved the dynamic migration mechanism, prediction probability algorithm and memory compression algo- rithm is put forward. Through experiment and comparative analysis, it was proved that the improved framework and algorithm on the virtual machine live migration can reduce the amount of data transmission, shorten downtime and improve the performance of the virtual machine live migration.
