Abstract

An address translation buffer in a virtual machine system is so arranged as to include a state descriptor address field for holding an address of a main memory at which a guest virtual machine state descriptor is located and which is designated by a guest virtual machine execution start instruction in addition to a pair of addresses for address translation. With this arrangement, the guest virtual machine associated with the paired addressed for address translation can be identified, while address translation information for a plurality of guest virtual machines can be simultaneously held in an address translation buffer.
