METHOD AND DEVICE FOR REALIZING VIRTUAL MACHINE MIGRATION

摘要

Provided are method and device for realizing virtual machine migration. The method comprises: after receiving information about a virtual machine group sent by an application management server, searching for the deployment location information about all the virtual machines in the virtual machine group according to this information so as to determine a destination physical machine set which can accommodate all the virtual machines in the virtual machine group and make the communication response time therebetween shorter than the current communication time, and then migrating the virtual machines in the virtual machine group running in physical machines which does not belong to the destination physical machine set to this set. With the present invention, on the premise that the virtual machines in a virtual machine group are migrated to a physical machine set which contains the fewest number of subnets and contains the fewest number of physical machines, rapid exchange of virtual machine communication data in the virtual machine group is realized, thus improving application user experience effectively.
