Abstract

The embodiment of the invention discloses a virtual machine hot migration method, device and system, which belong to the technical field of communication. The method includes: during the hot migration process of the target virtual machine, acquiring storage location information corresponding to pre-recorded target service configuration information, wherein the target service configuration information is used for a target virtual acceleration component corresponding to the target virtual machine Perform service processing; read the target service configuration information in the storage location corresponding to the storage location information; send the target service configuration information to the destination server, so that the destination server stores the target service configuration information. By adopting the invention, business processing failure can be prevented.

Description

technical field

[0001] The present application relates to the technical field of communications, and in particular to a method, device and system for live migration of a virtual machine. Background technique

[0002] In order to process more business packets on the network side server, technicians often install multiple virtual machines in the server, and each virtual machine can realize a certain function (for example, it can realize the function of encrypting and decrypting business packets), among which , an application for realizing a certain function may be installed in the virtual machine, that is, the virtual machine may realize the function through the installed application.

[0003] When the number of virtual machines installed in the server is large, the performance of the functions implemented by the virtual machines will decrease. On a server with a smaller number of machines (which may be called a destination server), the virtual machine can be live-migrated. ...
