Abstract
A hypervisor prepares a guest region identifier (RID)-physical region identifier (RID) mapping table for dynamically registering and managing items and performs RID conversion using the guest RID-physical RID mapping table. When the mapping table is used, since it is unnecessary to provide a specific information area representing logical partitions (LPARs) corresponding to respective guests in an RID to be converted, there is no limitation concerning the number of LPARs and a problem in operation can be eliminated.
