摘要

A control device includes a moving unit that moves a storage image of a machine that is currently used as a virtual machine environment, to a predetermined storage area, and a writing unit that, after a completion of a move by the moving unit, writes a new storage image including an operating system in a physical machine environment, to the machine in which the move is completed.

主权项

1. A non-transitory computer-readable recording medium having stored therein a migration control program that causes a computer to perform a process comprising:
first live migrating all virtual machines running on a first virtual machine platform of a first physical machine to a second virtual machine platform of a second physical machine, wherein the first and second virtual machine platforms are of the same type; moving the first virtual machine platform to a database; writing a storage image including an operating system of a physical machine environment to the first physical machine; restarting the first physical machine; executing, by the first physical machine, batch jobs remaining in a queue; moving the storage image to the database; writing the first virtual machine platform to the first physical machine; second live migrating the first live migrated virtual machines from the second virtual machine platform back to the first virtual machine platform.
