Abstract

The embodiment of the present invention discloses a method and device for migrating a virtual machine, which relates to the field of communication technology, and can solve the problem of data migration after migration of a virtual machine that executes a task generated by the same application in a cloud computing data center under the condition of concentrated resources. The problem of high resources occupied by transmission. The method in the embodiment of the present invention includes: when the obtained resource utilization rate of the physical server is greater than the resource utilization rate upper limit, dividing all virtual machines into at least one virtual machine set; according to the resource utilization of each virtual machine in the at least one virtual machine set Determine the virtual machine to be migrated on the physical server until the sum of the resource utilization of all virtual machines on the physical server except the virtual machine to be migrated is less than or equal to the upper limit of resource utilization; according to the obtained migration bandwidth, the virtual machine to be migrated Virtual machines that belong to the same collection of virtual machines in the same virtual machine are migrated to a single physical server other than the physical server. The invention is suitable for cloud computing data center.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for migrating a virtual machine. Background technique [0002] With the development of communication technology, especially the popularity of virtualization technology, cloud computing data centers usually use virtual machines to perform tasks. In practical application, in order to save the energy consumption of cloud computing data center, the resource concentration of cloud computing data center can be achieved through the method of virtual machine migration, that is, the virtual machine is centralized migrated to a few physical servers to execute the cloud computing data center. task, and at the same time shut down the physical server from which the virtual machine has been evacuated. [0003] In practical applications, data transmission is required between multiple virtual machines executing tasks generated by the same application. Moreover, the f...
