Abstract

An embodiment of the invention discloses a method and device for on-line integral migration of a virtual machine. The invention relates to the field of communication. Source virtual machine storage is divided into a basic file and other files according to the migration levels of a source virtual machine. First, the basic file is copied to a target host machine to enable the virtual machine to be started quickly in the target host machine, and therefore the service migration time of the virtual machine is greatly shortened. The method comprises the steps of receiving the migration level corresponding to the source virtual machine and sent by a central controller, and dividing the source virtual machine storage into the basic file and the other files according to the migration level corresponding to the source virtual machine; sending the basic file to the target host machine so that the virtual machine can be started in the target host machine according to the basic file; releasing source virtual machine resources; sending the other files to the target virtual machine.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for online overall migration of a virtual machine. Background technique [0002] Virtualization technology is to virtualize the physical resources of a host into multiple virtual machines (Virtual Machine, VM for short), and each virtual machine can share the physical resources of the host and independently implement functions similar to the host. The online overall migration of virtual machines refers to the migration of virtual machines between different hosts and different shared storage domains under the premise that the business on the virtual machine is running normally and the service is not interrupted. [0003] Virtual machine online overall migration technology is essentially a combination of virtual machine online migration and virtual machine online storage migration technology. In shared-no-storage virtual machine online overall migration technol...
