A virtual machine image generating means (102) assembles a device file saved at a virtual machine component storing means (101), a virtual device setting file, and three disc images (an OS disc image, a provisioning disc image and a user data disc image) to generate a virtual machine image. A virtual machine image distributing means (103) distributes the virtual machine image generated by the virtual machine image generating means (102). A disc map generating means (106) makes out maps of regions where writing is prohibited and a collection is carried out.</p> |
