Abstract

The invention discloses an on-line migration method of a virtual machine. The method comprises the steps of pretreating a source server and a target server before migration; completely copying current stored data of the virtual machine to the target server; when a change scale of the current stored data of the virtual machine and stored data in the last circulation reaches to the preset standard, copying a current dirty page into the target server until the number of the current dirty pages of the virtual machine is smaller than a preset value; stopping the source server, and copying a dirty page of the last circulation and a current working state of the source server into the target server; controlling the virtual machine to migrate to the target server from the source server. The stop time required by the method provided by the invention is the time consumed for copying the dirty page in the last circulation, so that compared with the prior art, at the earlier stage of stop, the virtual machine cannot be influenced to provide service to a user through the method, and the stop time is greatly reduced. In addition, the invention also provides an on-line migration device of the virtual machine with the same effects.

Description

technical field [0001] The invention relates to the technical field of virtual machine management, in particular to a method and device for online migration of a virtual machine. Background technique [0002] With the advancement of technology and the development of technology, localized big data virtualization software has attracted more and more attention from banks, governments, military forces and major enterprises, followed by the upgrading of virtualization software, which customers are most concerned about There is nothing better than replacing virtualization software without affecting the normal operation of the business. The carrier of the customer's business operation is a virtual machine. After replacing the virtualization software platform, how to migrate the virtual machine running on the source server to the The target server becomes a critical issue. [0003] In the prior art, there are offline or online migration methods in the migration process of the virt...
