Abstract

The purpose of the present invention is to provide a computer which is capable of increasing the number of I/O devices which connect to a PCI fabric which has predetermined specifications. This computer comprises: a storage unit which retains an I/O device list which is used to manage the allocation to a virtual machine which runs on the computer of an I/O device which is connected to the computer via a network; a virtual machine monitor which identifies the I/O device which is required for the operation of the virtual machine; and an I/O device manager which refers to the I/O device list and assesses whether the I/O device which has been identified by the virtual machine monitor is available to be allocated to the virtual machine, and if there is an I/O device available to be allocated to the virtual machine, allocates the I/O device to the virtual machine, and registers in the storage unit an identifier which is assigned to the I/O device on the basis of predetermined specifications, together with an identifier of the virtual machine.

Dependent claims

A computer comprising:

a storage unit that stores an I/O device list for managing allocation of an I/O device to a virtual machine operating on the computer, the I/O device being connected to the computer through a network;
a virtual machine monitor that specifies an I/O device required for operation of the virtual machine;
and
an I/O device manager that determines whether or not an I/O device specified by the virtual machine monitor is allocable to the virtual machine, by referring to the I/O device list, and when an I/O device allocable to the virtual machine exists, allocates the I/O device to the virtual machine and, along with an identifier of the virtual machine, stores, in the storage unit, an identifier assigned to the I/O device in accordance with a predetermined specification.
