Abstract
An information processing apparatus includes a control operating system executing a process for allocating a plurality of logical processors to a physical processor in a time division manner, and a guest operating system for which a logical partition as an application entity of the logical processor is set. The control operating system sets and updates, as address conversion tables for determining an allocation relationship between the logical processor and the physical processor, two address conversion tables of a first conversion table that sets an allocation relationship between a logical partition address space and a physical address space and a second conversion table that sets an allocation relationship between a virtual address space in the guest operating system and the physical address space.
