Abstract:
A migration source virtual server and a migration destination virtual server respectively include a volume information management unit for associating and managing volume identifying information for identifying the logical volumes and the logical volumes managed by the management OS of the migration source virtual server and the management OS of the migration destination virtual server; an identification unit for the migration source virtual server and the migration destination virtual server to identify the same logical volume as a target logical volume based on the volume identifying information; and a virtual OS migration unit for migrating data in an memory area used by a virtual OS of the migration source virtual server to the migration destination virtual server, and migrating update data in the memory area to be updated during the migration to the migration destination virtual server.
