Claim Text:
1. A virtual machine deployment method comprising: specifying, using a processor, a second virtual machine that provides a service on which a first virtual machine depends; determining, using the processor, whether a dependency direction of a service and a dependency direction of a parameter are opposite from one another for the first virtual machine by referring to application information which associates an application with information on whether the dependency direction of the service and the dependency direction of the parameter are opposite or not between a virtual machine associated with the application and another virtual machine; setting, using the processor, a pointer which causes the second virtual machine to refer to a parameter that is used to create a disk image of the first virtual machine when the dependency direction of the service and the dependency direction of the parameter are opposite for the first virtual machine; setting, using the processor, the pointer indicating that the second virtual machine is to be used as a reference target when the dependency direction of the service and the dependency direction of the parameter are not opposite for the first virtual machine; and deploying, using the processor, the first virtual machine and the second virtual machine by creating, in accordance with the pointer, a disk image of the second virtual machine from the parameter that is set when a resource of the first virtual machine is allocated.
