MIGRATION MANAGEMENT APPARATUS, MIGRATION MANAGEMENT METHOD, AND MIGRATION MANAGEMENT PROGRAM

摘要

A migration management apparatus simulates the migration of each VM guest being a migration target to decide a migration destination VM host. Next, the migration management apparatus decides a migration mode of a VM guest whose migration destination VM host has been decided based on the power status of the VM guest. When the migration destinations and migration modes of the VM guests being the migration targets have been decided, the migration management apparatus subsequently migrates the VM guests in one batch to their respective decided migration destinations in their respective decided migration modes.
