Virtual machine deployment method, deployment execution program, and deployment execution device

摘要

PROBLEM TO BE SOLVED: To deploy OS's of a plurality of virtual machines by a simple preparing operation, without increasing the time required for copying processing of image files or excessively limiting the network bandwidth available for copying processing as a result of a bottleneck caused by the network bandwidth or the storage bus bandwidth.SOLUTION: By activating a virtual machine (Xi) that is a copy source of an OS, an image file of the OS used by the virtual machine (Xi) is generated. After the image file is transferred to another virtual machine (Xi+1) via a telecommunication network 2, the virtual machine (Xi+1) changes a security identifier of the image file into a security identifier of the virtual machine (Xi+1) and makes the image file an OS to be used by the virtual machine (Xi+1). This process is repeated on virtual machines (Xi), while i=0, 1, 2,...n.
