Abstract:
A server LPAR operating in a virtualized computer shares pages with client LPARs using a shared memory region (SMR). A virtualization function of the computer receives a get-page-ID request associated with a client LPAR to identify a physical page corresponding to a shared page included in the SMR. The virtualization function requests the server LPAR to provide an identity of the physical page. The virtualization function receives a page-ID response comprising the identity of a server LPAR logical page that corresponds to the physical page. The virtualization element determines a physical page identity and communicates the physical page identity to the client LPAR. The virtualization element receives a page ID enter request and enters an identity of the physical page into a translation element of the computer to associate a client LPAR logical page with the physical page.

Claim (Index 8):
A computer program product for sharing a physical memory page among a plurality of logical partitions (LPARs) included in a computer, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:\n receiving a get-page-ID request that includes an identity of a shared page and an identity of a shared memory region (SMR) that includes the shared page, wherein the SMR is associated with a first LPAR and the get-page-ID request is associated with a second LPAR; communicating to the first LPAR a request to identify a physical page in a physical memory of the computer that corresponds to the shared page; receiving, in response to the get-page-ID request, a page ID response that comprises an identity of a first logical page that corresponds to the shared page and the physical page; communicating to the second LPAR, in response to the page ID response, a first identity of the physical page, wherein the first identity of the physical page is an encrypted page number corresponding to the physical page; converting the encrypted page number to a physical page number; and entering the physical page number into an address translation element, wherein the address translation element is operative to translate the identity of the physical page number to a physical page address of the physical page.
