TLB Virtualization Method of Machine Virtualization Device, and Machine Virtualization Program

Abstract

A TLB virtualization method of a machine virtualization device which, in the case where a TLB is shadowed in a virtualization environment, avoids TLB entry conflicts and is capable of improving the performance of a virtualization environment; wherein a hypervisor is executed on a real machine, an OS is operated on a plurality of virtual machines generated by means of processing based on the hypervisor, TLB entry calculations are carried out using RID values in the virtual machines by means of hypervisor processing, the RID values in the virtual machines used in the TLB entry calculations in the real machine are translated into different values in said plurality of virtual machines, and, further, the values of the bit strings of translated RID values are modified.
