A virtual storage management method in a multi-processor system in which individual processors share an external storage is shown. Data of the virtual storage is stored in the shared external storage, and a page table for managing the virtual storage of each processor is also stored in the shared external storage. By exclusively controlling an access to that page table, the virtual storage can be managed.
