Abstract
A computer system operable as a virtual machine system capable of accessing multiple virtual address spaces, which has an access register translation means for translating a space identifier into an origin address of a table for address translation and a translation pair memory for storing translation pairs of the space identifiers and the associated origin addresses. In each entry of the translation pair memory, a field is provided in association with the translation pair, for storing a machine identifier of the guest virtual machine associated with the translation pair. When accessing a virtual address space, a guest virtual machine makes reference only to the associated translation pair based on the virtual machine identifier thereof.
