摘要： Managing computer memory in a computer with dynamic logical partitioning that operates transparently with respect to operating systems in logical partitions. Exemplary methods, systems, and products are described for managing computer memory in a computer with dynamic logical partitioning that include copying by a hypervisor, from page frames in one logical memory block (“LMB”) of a logical partition (“LPAR”) to page frames outside the LMB, contents of page frames having page frame numbers in a page table for an operating system in the LPAR. Embodiments typically include storing new page frame numbers in the page table, including storing by the hypervisor, for each page frame whose contents are copied, a new page frame number that identifies the page frame to which contents are copied. In typical embodiments, copying contents of page frames and storing new page frame numbers are carried out transparently with respect to the operating system.
