ABSTRACT
In recent years, with the fast development of cloud computing, virtualization technology has got considerable progress, which has also provided a solid foundation for the rapid development of cloud computing. After the large-scale use of virtualization technology by IDC (Internet Data Center), the number and load of virtual machine will change frequently along with the demand of users, so it has provided challenges for the resource scheduling of the virtual machine cluster. Virtual machine migration technology [1] can migrate the whole operation environment (including the operating systems) from one physical server to another physical server, so as to effectively manage the data center resources and get convenient for the maintenance and energy saving of the physical server.
