摘要
为了提高虚拟机备份(包括运行时状态、存储、配置)的效率,提高虚拟机运行的稳定性和平衡物理机的负载,提出一种基于混合迁移的OpenStack云平台虚拟机在线迁移方案.该方案对虚拟机迁移采取共享存储迁移和存储块迁移相互结合的方式,以平衡OpenStack云平台虚拟机在线迁移速度及备份有效性.结果表明:所提出的混合迁移方案能有效地提高OpenStack备份效率,同时减少虚拟机在线迁移的时间和提高虚拟机迁移容错能力.
A virtual machine live-migration improvement based on hybrid-migration was presented to improve the efficiency of the backup for virtual machines(including the running-state,storage and configurationinformation),stability of the running virtual machines and the balance for physics machines.Shared storage migration and storage block migration were blended to balance the speed for live-migration of virtual machines in the validity of backup.The practical result showed that the proposed virtual machine livemigration improvement solution can effectively improve the efficiency of the backup for virtual machines,reduce the time of live-migration and improve the fault-tolerant ability.
