Abstract
A method and system for managing images of virtual machines hosted by a server. The server maintains a base virtual machine image in a common data store for sharing by the virtual machines. When the server identifies an image modification for at least one of the virtual machines, the server determines whether the image modification includes data common to images of the other virtual machines. If so, the common data is copied to the base virtual machine image in the common data store, and a pointer to the copied data is added to an image of the virtual machine in an individual data store.
