Embodiment Construction

[0062] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0063] The existing cloud server migration solutions mainly include: cold migration (shutdown migration), the specific process can be: first turn off the power of the physical machine where the virtual machine is located, and then migrate the virtual machine and associated disks to the new physical machine cluster , the virtual machine can only be restarted after all data migration is complete. Due to the large amount of data being migrated, the downtime is longer.

[0064] Based on the above problems, the embodiment of the present application proposes a virtual machine migration method, which can quickly migrate the virtual machine to another cluster and restore the normal operation of the virtual machi...

Abstract

The embodiment of the invention provides a virtual machine migration method, which comprises the following steps that: determining a virtual machine on a first cluster; stopping the virtual machine; determining a first physical machine in a second cluster, and migrating the virtual machine to the first physical machine from the first cluster; obtaining the disk information of a first disk relatedto the virtual machine; and on the basis of the disk information, creating a second disk, and mounting the second disk to the virtual machine of the first physical machine. In the embodiment of the invention, the virtual machine in an old cluster is migrated to a new cluster, the new disk is created on the basis of the disk information of the old disk related to the virtual machine, and the new disk is related to the migrated virtual machine. After the migrated virtual machine is related to the new disk, the virtual machine can be started. In the embodiment of the invention, when the virtual machine is migrated, not all disk data needs to be migrated so as to shorten data transmission time and shorten virtual machine downtime, and the quick migration of the virtual machine is realized.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a virtual machine migration method and a virtual machine migration device. Background technique [0002] For cloud service providers, regularly improving the performance of cloud servers is an important means to improve competitiveness. A cloud server is actually a server composed of a virtual machine (Virtual Machine). A virtual machine refers to a system virtual machine, that is, a complete computer system that can be simulated, has complete hardware system functions, and runs in a completely isolated environment. [0003] Virtual machine systems are installed and run on physical machines, and cloud service providers generally build physical machines into clusters. One of the main means for cloud service providers to improve the performance of cloud servers is to migrate cloud servers from current physical machine clusters to physical machine clusters with better ...
