Abstract
An information system includes host computers having virtual machine programs running thereon for generating virtual machines. A storage system in communication with the host computers stores an image file corresponding to each virtual machine running on the host computers. In some embodiments, when the storage system receives an access request to a particular image file corresponding to a particular one of the virtual machines running on one of the host computers, the storage system determines whether the access request is authorized based upon an identifier of the particular virtual machine and a location of the particular virtual machine. In some embodiments, the storage system sends an inquiry to a management computer when determining whether the access request is authorized and, based upon the location of the particular virtual machine and the identifier of the particular virtual machine, the management computer sends a reply as to whether the access request is authorized.
