Patent ID: 8799896

Claim:
A computer-readable, non-transitory storage medium storing a program for causing a computer to execute a virtual system control process, the virtual system control process comprising: receiving a deployment request for requesting to deploy a specific type of a test system for a specific virtual system in a physical server pool in which operational and test virtual systems can be deployed; first activating plural types of virtual machines necessary for said operational system of said specific virtual system in said physical server pool by using first server configuration data in configuration information for said operational system of said specific virtual system and a first virtual machine image for said operational system of said specific virtual system; second activating plural types of virtual machines to be added to said operational system of said specific virtual system in said physical server pool by using second server configuration data in configuration change information representing configuration information concerning difference between said operational system and said specific type of said test system for said specific virtual system and a second virtual machine image for the virtual machine relating to said difference, said plural types of virtual machines to be added to said operational system play additional roles to roles which said plural types of virtual machines necessary for said operational system play; identifying a first link that is included in a network of said operational system and is not included in a network of said specific type of said test system, and a second link that is not included in said network of said operational system and is included in said network of said specific type of said test system, by using said configuration change information; and setting said first link to be deleted from said operational system and said second link to be added to said operational system.
