Accessing corresponding alternative operation configuration information of applications running on virtual machines based on requested configuration information indicating data format conversion and user name

摘要

A setting storage unit stores first setting information that defines an operation of a first application that runs on a guest OS and second setting information that defines an operation of a second application that runs on at least one of another guest OS and a host OS. A correspondence storage unit stores first identification information for identifying the first setting information and second identification information for identifying the second setting information, in association with each other. An alternative access gaining unit reads from the correspondence storage unit the second identification information corresponding to the first identification information of the first setting information for which an access request is received, and accesses the second setting information of the second identification information that is read out, in place of the first setting information for which the access request is received.
