Virtual machine deployment method, recording medium, and information processing apparatus

摘要

An information processing apparatus 10 specifies a second virtual machine that provides a service on which a first virtual machine depends. The information processing apparatus 10 sets a pointer between the first virtual machine and the second virtual machine by referring to application information associated with, for each application, a parameter type, of another virtual machine, that is used to create a disk image of a virtual machine associated with an application and that is attached when a resource is allocated to the other virtual machine. The information processing apparatus 10 deploys the first virtual machine and the second virtual machine by creating, in accordance with the pointer, a disk image of the second virtual machine or the first virtual machine from a parameter that is set when a resource of the first virtual machine or the second virtual machine.

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.
