Embodiment Construction
[0027] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings that form a part hereof.
[0028] image 3 is a diagram showing an address space used in address translation processing for full virtualization according to an embodiment of the present invention.
[0029] Such as image 3 As shown in , virtual machine 110 and virtual machine monitor 120 independently have separate address spaces. In order to make the virtual machine 110 and the virtual machine monitor 120 independently have a separate address space, a separate page table is allocated to the virtual machine 110 and the virtual machine monitor 120 respectively, and the separate page table is divided into a virtual machine page table 130 and a virtual machine monitor Page Table 140.
[0030] The memory management unit (MM) 150, which is a hardware component for address space transformation, selectively instructs the page table representing the address space t...
