Abstract
An aspect includes a method for sharing memory in a computer system that includes receiving a request, from a logical partition (LPAR) executing on a processor, for a page in a shared physical memory to be moved into a logical page of a logical memory of the LPAR. It is determined, by the hypervisor, that the page is physically located in a hypervisor paging device. It is determined whether the request is from a paging process executing at the LPAR to migrate the logical page to a local paging device to make room for an other logical page in the logical memory. Based on determining that the request is from the paging process, the logical page is marked to indicate that the physical page is on the hypervisor paging device and a new logical page is added to the logical memory for the other logical page.
