【摘要】 虚拟机技术可以使硬件和软件明确分开,还能实现容错管理、动态负载均衡、服务器在线维护,对于提高数据中心和集群的服务性能尤其有利。设计并实现了4种负载类型的虚拟机在XEN上的迁移实验,比较了不同负载对于动态迁移的影响,以及动态迁移相对于静态迁移的优越性。更多还原

【Abstract】 Virtual machine technology is a good way to separate software and hardware in the same physical machine,and is beneficial to fault management,dynamic load balancing and online server maintenance.It is especially useful in optimizing the performance of data center and cluster.To compare the performance of stop and copy migration and live migration,as well as to compare the impact of different tasks on live migration,this paper migrated four kinds of virtual machines with different tasks in LAN,using XEN as a virtual machine monitor.更多还原
