Virtualization infrastructure management apparatus, virtualization infrastructure management system, virtualization infrastructure management method, and virtualization infrastructure management program

摘要

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 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 in standby state, in a management information storage unit 44 for storing the states of physical machines 50-1 to 50-n; and an allocation unit 43 for, when a fault occurs in physical machine 50-j, re-allocating virtual machine 51-j stopped by the fault to any of the physical machines for which the standby state is registered in the management information storage unit 44.
