虚拟机实时迁移 [1,2]可以实现将一台虚拟机在运行状态下迁移到另一台物理机上,可以用于服务器资源整合、负载均衡、节能省电和物理机例行维护等应用.然而,当前的虚拟机实时迁移只能达到人工迁移,而不能实现全自动迁移.当虚拟机较少时还可以人工操作,但当前数据中心规模常常有几千至上万台服务器,当有几十台甚至几百台发生高负载时,人工迁移效率是很低的,并有可能会耽误迁移时机造成一些服务器长时间过载甚至出现宕机.
虛擬機實時遷移 [1,2]可以實現將一檯虛擬機在運行狀態下遷移到另一檯物理機上,可以用于服務器資源整閤、負載均衡、節能省電和物理機例行維護等應用.然而,噹前的虛擬機實時遷移隻能達到人工遷移,而不能實現全自動遷移.噹虛擬機較少時還可以人工操作,但噹前數據中心規模常常有幾韆至上萬檯服務器,噹有幾十檯甚至幾百檯髮生高負載時,人工遷移效率是很低的,併有可能會耽誤遷移時機造成一些服務器長時間過載甚至齣現宕機.

Virtual machine live migration can be a virtual machine migration in the operating state to another physical machine can be used for server resource integration, load balancing, energy saving and physical routine maintenance applications. However, the current virtual machine live migration can only reach a human migration, and automated migration can not be achieved. When a virtual machine can have fewer manual operations, but the scale of today's data centers often have thousands offi rst million servers, when there are dozens or even hundreds of high load occurs, obviously artifi cial migration effi ciency is very low, and there isIt may delay the timing of migration caused by some servers for a long time overload even downtime. Heavy load for the server presents a hotspot automatic migration program.
