摘要

A virtualization system comprises a plurality of host machines on which a virtual machine operates, a plurality of storages connected to the host machines through a fiber-channel switch; and a switch controller, the switch controller including a migration management unit which instructs the host machine on migration of the virtual machine, wherein the migration management unit instructs the fiber-channel switch connected to a migration destination to set host bus information so as to allow an access to the storage used at a migration source by the virtual machine which has migrated.
