摘要: 针对广域网(WAN)环境下虚拟机(VM)迁移存在的诸多问题提出一种迁移模型。该模型持续检测节点间链路状态,优化磁盘、内存和CPU状态及网络的迁移时序,并采用磁盘周期同步、单向网络隧道及虚拟机本地化等方法。实验表明:模型减少了虚拟机跨WAN迁移的数据量,缩短了网络重定向路径,在模拟实验中迁移的总时间及暂停时间接近于共享存储方式。

关键词: 广域网, 虚拟机, 在线迁移, 磁盘迁移, 网络重定向

Abstract: Concerning the Virtual Machine (VM) migration problems in Wide Area Network (WAN), a live migration model was proposed. The link state between nodes was continuously detected, and the migration time of disk, memory, CPU status and network were optimized. The disk cycle synchronization, unidirectional tunnel and virtual machine localization were implemented. The experimental results show that the model reduces amount of migration data and shortens redirection path in WAN. The total time and pause time are close to the manner of shared storage under simulated conditions.

Key words: Wide Area Network (WAN), Virtual Machine (VM), live migration, disk migration, network redirection
