VIRTUAL SYSTEM, SWITCH CONTROLLER, FIBER CHANNEL SWITCH, MIGRATION METHOD, AND MIGRATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a virtual system in which a virtual machine, which accesses a physical HBA directly, is migrated.SOLUTION: A virtual system 1000 includes: a plurality of host machines 100 or 200 in which a virtual machine 110 operates; a plurality of storages 140 or 240 connected via a fiber channel switch 130 or 230 to the host machines 100 or 200; and a switch controller 300. The switch controller 300 includes migration management means for directing migration of the virtual machine 110 to the host machine 100 or 200; and the migration management means instructs setting of host bus information to a fiber channel switch connected to a migration destination so that the virtual machine 110 after the migration can access to a storage used by a migration source.
