VIRTUAL MACHINE MANAGEMENT DEVICE, VIRTUAL MACHINE MANAGEMENT SYSTEM, VIRTUAL MACHINE MANAGEMENT METHOD AND VIRTUAL MACHINE MANAGEMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a management device, a management system, a management method and a management program, capable of surely moving a virtual machine.SOLUTION: In a management device 12, a relay point calculation function unit 14 calculates a relay point (100), and a virtualization resource control function unit 17 acquires resource information of a virtual machine of a movement object from a data center DC1 of a movement source (202). The management device requires securement of a resource with the acquired resource information of the virtual machine of the movement object, at the virtualization resource control function part (104). In a data center DC2 of the relay point and a data center DC3 of a movement destination, according to the requirement from the management device, the resource of the virtual machine of the movement target is secured in a usable manner. Consequently, before movement of the virtual machine, a resource that the virtual machine uses can be secured.SELECTED DRAWING: Figure 14
