一种基于Xen的虚拟机自动迁移系统设计

s the server virtualization widely applied to cloud computing datacenter, the technique develop rapidly, especially live migration of virtual machine. Because of the advantage that live migration can be used in resource integration, load balancing, power saving and machine routine maintenance, it has become one of the most important technique in server virtualization. However, the migration can only be implemented manually by the administrator. Suppose tens or hundreds of physical machines are overloaded, the administrator can not deal with such problem immediately. In this paper, we design an auto-migration system,which can discover the hotspot machine and automaticly recognize the scenario pattern, then migrate the virtual machine to specified physical machine. The process of migration can executed automatically and the system can implement load ballancing and power saving.
