Virtualization substrate management device, virtualization substrate management system, virtualization substrate management method, and recording medium for recording virtualization substrate management program

Abstract

The disclosed device makes it possible to effectively use a usable physical machine in a computer system for building a virtualization environment. A virtualization infrastructure management deviceequipped with: a detection unitfor detecting the occurrence of an accidental fault which is not a physical persistent fault, in physical machine-which is capable of executing virtual machine-; a registration unitfor registering that physical machine-is in standby state, in a management information storage unitfor storing the states of physical machines-to-; and an allocation unitfor, when a fault occurs in physical machine-, re-allocating virtual machine-stopped by the fault to any of the physical machines for which the standby state is registered in the management information storage unit
