VIRTUALIZATION SUBSTRATE MANAGEMENT DEVICE, VIRTUALIZATION SUBSTRATE MANAGEMENT SYSTEM, VIRTUALIZATION SUBSTRATE MANAGEMENT METHOD, AND RECORDING MEDIUM FOR RECORDING VIRTUALIZATION SUBSTRATE MANAGEMENT PROGRAM

摘要

The present invention makes it possible to effectively use a usable physical machine in a computer system for building a virtualization environment. A virtualization substrate management device 40 equipped with: a detection unit 41 for detecting the occurrence of an accidental fault which is not a physical persistent fault, in physical machine 50-i which is capable of executing virtual machine 51-i; a registration unit 42 for registering that physical machine 50-i is standing by, in a management information storage unit 44 for storing the states of physical machines 50-1 to 50-n; and a distribution unit 43 for, when a fault occurs in physical machine 50-j, re-distributing virtual machine 51-j stopped by said fault to any of the physical machines for which a standby state is registered in the management information storage unit 44.
