    摘要: Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.

    摘要: Multiple logical partitions are provided access to a self-virtualizing input/output device of a data processing system via multiple dedicated partition adjunct instances. Access is established by: interfacing each logical partition to one or more associated partition adjunct instances, each partition adjunct instance coupling its associated logical partition to one of a virtual function or a queue pair of the self-virtualizing input/output device, and each partition adjunct instance being a separate dispatchable state and being created employing virtual address space donated from the respective logical partition or a hypervisor of the data processing system, and each partition adjunct instance including a device driver for the virtual function or queue pair of the self-virtualizing input/output device; and providing each logical partition with at least one virtual input/output which is interfaced through the logical partition's respective partition adjunct instance(s) to a virtual function or queue pair of the self-virtualizing input/output device.

    摘要: Automated management of partition service assignment to a virtual input/output (VIO) adapter is provided. Responsive to creation of a new partition service in a data processing system, a partition priority number is determined for the new partition service, and, for each VIO adapter, the partition priority numbers of the partition services currently assigned to that VIO adapter are summed. For a VIO adapter with a lowest sum of partition priority numbers, logic determines whether assigning the new partition service to that VIO adapter results in its summed partition priority number being above a predefined threshold, and the new partition service is assigned to a VIO adapter based, at least in part, on whether assigning the new partition service to the VIO adapter with the lowest sum of partition priority numbers results in that VIO adapter's summed partition priority number exceeding the predefined threshold.
