摘要

虚拟机动态迁移技术为虚拟化系统的资源调度提供了强有力的支撑，Post-Copy算法作为虚拟机动态迁移的两个核心算法之一，凭借其总体迁移时间稳定与迁移停机时间短的优点，一直是国内外学者研究的热点问题。对虚拟机的故障容错机制、迁移过程中的内存页面传输方式与缺页错误的关联性，以及QEMU-KVM平台源码进行了深入的研究，提出了基于事务同步的故障容错方法以提升Post-Copy迁移算法的稳定性。试验结果表明，提出的虚拟机Post-Copy迁移优化算法，能保证迁移过程中源端虚拟机故障、目标端虚拟机故障以及网络故障的迅速修复，能通过较小的代价解决稳定性问题，所提出的方法有效地提升了Post-Copy迁移算法的稳定性，也为以后的优化研究方向提供了参考。

Abstract

The dynamic migration technology of virtual machine provides a strong support for the resource scheduling of virtualization system.As one of the two core algorithms of virtual machine dynamic migration

Post-Copy algorithm has been a hot issue for scholars at home and abroad for its advantages of stable migration time and short migration downtime.The fault tolerance mechanism of virtual machine

the connection between the transfer mode of memory page and the page missing error during the migration process

and the source code of QEMU-KVM platform were studied.A fault tolerant method based on transaction synchronization was proposed to improve the stability of the Post-Copy migration algorithm.The experimental results show that the proposed algorithm can ensure the fast repair of deep end virtual machine failure

target virtual machine failure and network fault during the migration process

and solve the stability problem at a small cost.The method proposed effectively improves the stability of the Post-Copy migration algorithm

and provides reference for the future optimization research direction.
