VOI-based mirror image operation implementation method and system

The invention relates to the technical field of cloud computing, and provides a VOI-based mirror image operation implementation method and system. The method comprises the following steps: in a VOI scene, pre-installing a required application system at a client, making a system mirror image template based on an existing operating system of the client, and uploading the system mirror image template to a server; the server creates a target based on the uploaded system mirror image template and defines attributes of the system mirror image template; and in response to requests of other clients, downloading the system mirror image template to the requesting client, and guiding the system mirror image template to perform local system mirror image operation. According to the method and the device, the client can download a plurality of template mirror images, and one of the template mirror images is selected to start according to needs, so that different application environments are operated. 本发明涉及云计算技术领域，提供了一种基于VO
