摘要： In response to a hypervisor page fault for memory that is not resident in a shared memory pool, an I/O paging request is sent to an external storage paging space. In response to a paging service partition encountering an I/O paging error, a paging failure indication is sent to the hypervisor. A simulated machine check interrupt instruction is sent from the hypervisor to the shared memory partition and a machine check handler obtains control. The machine check handler performs data analysis utilizing an error log in an attempt to isolate the I/O paging error to a process or a set of processes in the shared memory partition. The process or set of processes associated with the I/O paging error, or the shared memory partition itself, may be terminated. Finally, the shared memory partition may clear or initialize the page associated with the I/O paging error.

摘要： Transparent hypervisor pinning of critical memory areas is provided for a shared memory partition data processing system. The transparent hypervisor pinning includes receiving at a hypervisor a hypervisor call initiated by a logical partition to register a logical memory area of the logical partition with the hypervisor. Responsive to this hypervisor call, the hypervisor transparently determines whether the logical memory is a critical memory area for access by the hypervisor. If the logical memory area is a critical memory area, then the hypervisor automatically pins the logical memory area to physical memory of the shared memory partition data processing system, thereby ensuring that the memory area will not be paged-out from physical memory to external storage, and thus ensuring availability of the logic memory area to the hypervisor.

摘要： Hypervisor managed memory paging is provided in a data processing system having multiple logical partitions. The data processing system includes a shared memory pool defined within physical memory. The shared memory pool includes a volume of physical memory with dynamically adjustable sub-volumes or sets of physical pages associated with the multiple logical partitions. Each sub-volume or set is associated with a particular logical partition and includes mapped logical memory pages for that logical partition. A hypervisor memory manager interfaces the multiple logical partitions and the shared memory pool, and manages access to logical memory pages within the shared memory pool. The hypervisor memory manager further manages page-out and page-in of logical memory pages from the shared memory pool to one or more external paging devices. This page-out and page-in managing by the hypervisor memory manager is transparent to the multiple logical partitions.

摘要： Migration management is provided for a shared memory logical partition migrating from a source system to a target system. The management approach includes managing migration of the logical partition from the source system to the target system by: transferring a portion of logical partition state information for the migrating logical partition from the source system to the target system by copying at the source system contents of a logical page of the migrating logical partition into a state record buffer for forwarding to the target system; forwarding the state record buffer to the target system; and determining whether the migrating logical partition is suspended at the source system, and if not, copying at the target system contents of the state record buffer to paging storage of the target system, the paging storage being external to physical memory managed by a hypervisor of the target system.

摘要： Hypervisor page fault processing logic is provided for a shared memory partition data processing system. The logic, responsive to an executing virtual processor of the shared memory partition data processing system encountering a hypervisor page fault, allocates an input/output (I/O) paging request to the virtual processor from an I/O paging request pool and increments an outstanding I/O paging request count for the virtual processor. A determination is then made whether the outstanding I/O paging request count for the virtual processor is at a predefined threshold, and if not, the logic places the virtual processor in a wait state with interrupt wake-up reasons enabled based on the virtual processor's state, otherwise, it places the virtual processor in a wait state with interrupt wake-up reasons disabled.
