Abstract

A method for offline updating virtual machine images is provided. The method comprises: an image security server collecting virtual machine image, extracting and storing information of the collected virtual machine image; and the image security server updating operation of the virtual machine image in offline mode based on the information of the collected virtual machine image. The method for offline updating virtual machine image disclosed in the present invention is more effective and is capable of updating virtual machine image in offline mode.

Description

technical field [0001] The present invention relates to an offline upgrade method, and more specifically, to a method for offline upgrade of a virtual machine image ("offline upgrade" as used herein means: upgrade the virtual machine image without starting the virtual machine). Background technique [0002] At present, with the increasingly wide application of computers and networks and the increasing variety of business types in different fields, the cloud computing environment has become more and more common and important. Usually, there are a large number of offline virtual machine images (or virtual machine templates) in the cloud computing environment, therefore, it is very critical to upgrade (ie, patch) the offline virtual machine images (or virtual machine templates). [0003] In the existing technical solutions, the following two methods are usually used to upgrade the offline virtual machine image: (1) upgrade the virtual machine online after the user generates it;...
