A computer implemented method, apparatus, and program product for extending virtual memory associated with logical partitions. A hosting partition receives a paging request from a logical partition on a logically partitioned data processing. The hosting partition identifies a location of the physical memory space on a remote computing device assigned to the logical partition and sends an extended virtual memory paging request to an extended virtual memory manager located on the remote computing device using a network connection. The extended virtual memory paging request comprises the instructions for the memory page-in or the memory page-out and the location of the physical memory space on the remote computing device that is being paged-in or paged-out. The extended virtual memory manager performs a page-in operation or a page-out operation in accordance with the instructions for the memory page-in or memory page-out.
