VIRTUAL MACHINE MANAGEMENT SYSTEM, MANAGEMENT SERVER, AND VIRTUAL MACHINE MANAGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To automatically and safely stop a virtual machine even when there is a need to immediately stop the virtual machine.SOLUTION: A virtual machine management system 1 includes: a plurality of uninterruptible power supplies 30 for supplying electric power to connected devices when a power failure occurs; a plurality of virtual servers 20 connected to each of the uninterruptible power supplies 30 and having one or a plurality of virtual machines 21; and a management server 10 for managing the order of stopping the virtual servers 20 and the virtual machines 21. When a power failure occurs, the management server 10 executes live migration which migrates a virtual machine 21 operating on a predetermined virtual server 20 to the other virtual server 20 on the basis of a preset stop order of the virtual machines 21 and a stop order of the uninterruptible power supplies 30, to sequentially stop the virtual machines 21 from a machine operating on the virtual server 20 connected to an uninterruptible power supply 30 which is high in the stop order of the uninterruptible power supplies 30.
