    摘要： The amount of host real storage provided to a large guest storage buffer is controlled. This control is transparent to the guest that owns the buffer and is executing an asynchronous process to update the buffer. The control uses one or more indicators to determine when additional host real storage is to be provided.

    摘要： A system, method and computer program product for providing quiesce filtering for shared memory. The method includes receiving a shared-memory quiesce request at a processor. The request includes a donor zone. The processor includes translation look aside buffer one (TLB1). It is determined that the shared-memory request can be filtered by the processor if there not any shared memory entries in the TLB1 and the donor zone is not equal to a current zone of the processor and the processor is not running in host mode. The shared-memory quiesce request is filtered in response to the determining.

    摘要： What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated and an initial origin address of a translation table of the hierarchy of translation tables are obtained. Dynamic address translation of the virtual address proceeds. In response to a translation interruption having occurred during dynamic address translation, bits are stored in a translation exception qualifier (TXQ) field to indicate that the exception was either a host DAT exception having occurred while running a host program or a host DAT exception having occurred while running a guest program. The TXQ is further capable of indicating that the exception was associated with a host virtual address derived from a guest page frame real address or a guest segment frame absolute address. The TXQ is further capable of indicating that a larger or smaller host frame size is preferred to back a guest frame.

    摘要： Mapping of address space by providing real storage including first and second address spaces. The second address space is smaller than and contained within the first address space. Provided within virtual storage is a system execution space. Providing within the system execution space is a system execution area having a size equal to or less than the second address space. The system execution area includes a control program having a first portion capable of addressing the first address space and the system execution space, a second portion constrained to address only the second address space and the system execution area, and at least one alias page. Responsive to a control program request for a first page in the virtual storage, a first frame is assigned in real storage corresponding to the page. Responsive to a request from the second portion of the control program for the first page, allocating an alias page in the system execution area, the alias page backed by the first frame.

    摘要： A method, system, program product and computer data structure for providing for two levels of server virtualization. A first hypervisor enables multiple logical partitions to share a set of resources and provides a first level of virtualization. A second hypervisor enables multiple, independent virtual machines to share the resources that are assigned to a single logical partition and provides a second level of virtualization. All events for all of the virtual machines within said single logical partition are grouped into a single partition-owned event queue for receiving event notifications from the shared resources for that single logical partition. A request for an interrupt is signaled for the grouped events from the partition-owned event queue for the demultiplexing of grouped events, by the machine, from the partition-owned event queue into individual, virtualized event queues that are allocated on a per virtual machine basis.
