    摘要： A virtual machine computer system permits more than one guest/virtual machine to share a single address space and each control access by its applications to the shared address space. The computer system comprises a host operating system for creating first and second virtual machine guests. The first guest responds to an address space creation request from a first application executing in the first guest to allocate an address space, by determining at least in part a storage region for the address space. The first guest also responds to a request from the first application to grant shared access by a second application executing in the second guest to the address space, by notifying the host operating system that the second guest or the second application is authorized to access the address space. The second guest responds to a request from the second application to access the address space, by determining that the second application has authority to access the address space. Then, the second guest grants access to the second application. The guest and host operating systems both participate in the address translation process for a host managed address space.

    摘要： Dynamic relocation of virtual machines among hypervisors in a domain is provided. A domain management module is executed on a computer processor and is configured to receive a request to add a new hypervisor to a domain. Each hypervisor and each domain comprises an architecture description (ARD). A new canonical ARD is generated for all hypervisors in the domain. A virtual machine executing on a first system is relocated to any other hypervisor in the domain. Virtual machines may also be moved to out-of-domain hypervisors through the use of override masks. In addition, under certain conditions, new hypervisors additions, as well as hypervisor and system updates may be performed without disrupting the virtual machines that are controlled by the hypervisors.

    摘要： Input/output interruptions are managed in computing environments that do not use dedicated per-guest interruption hardware to present interruptions. Dispatchable guest programs in the environment receive I/O interruptions directly without hypervisor intervention. This is facilitated by using one or more interruption controls stored in memory and associated with each guest program. For those guest programs that are not currently dispatchable, interruptions can be posted for the guests and notifications to the hypervisor can be aggregated. The hypervisor can then process a plurality of notifications for the plurality of guests in a single invocation.

    摘要： A method and apparatus for managing the execution on guest processors of a broadcast instruction requiring a corresponding operation on other processors of a guest machine. Each of a plurality of processors on an information handling system is operable either as a host processor under the control of a host program executing on a host machine or as a guest processor under the control of a guest program executing on a guest machine. The guest machine is defined by the host program executing on the host machine and contains a plurality of such guest processors forming a guest multiprocessing configuration. A lock is defined for the guest machine containing an indication of whether it is being held by a host lock holder from the host program and a count of the number of processors holding the lock as guest lock holders. Upon decoding a broadcast instruction executing on a processor operating as a guest processor, the lock is tested to determine whether it is being held by a host lock holder. If the lock is being held by a host lock holder, an instruction interception is recognized and execution of the instruction is terminated. If the lock is not being held by a host lock holder, the lock is updated to indicate that it is being held by the guest processor as a shared lock holder, the instruction is executed, and then the lock is updated a second time to indicate that it is no longer being held by the guest processor as a shared lock holder.

    摘要： A computer system for processing and committing data comprises a processor, an external storage device such as DASD or tape coupled to the processor, and a working memory such as RAM. An application program updates data in the working memory and then requests that the data be committed, i.e. written to the external storage device. In response, an operating system function determines which data or blocks have been changed and supplies to an I/O service an identification of the changed data or blocks to cause the I/O service to write the changed data or blocks to the external storage device. Thus, the application program is not burdened with the management of the I/O. The operating system permits the program to continue with other processing while the data is being written from the working memory to the external storage device. As a result, the program need not wait while the data is written to the external storage. Also, because little time is required of the program in the commit process, the program can frequently request commits. With frequent commits, there is less chance that the data will have been written to back-up memory or back-up storage (due to an overload of the working memory) between commits, and as a result, time will not be required to read the data from the back-up memory or storage into the working memory en route to the application program's external storage. Also, the frequent commits reduce the chance of overloading the I/O subsystem.

    摘要翻译： 用于处理和提交数据的计算机系统包括处理器，诸如DASD的外部存储设备或耦合到处理器的磁带以及诸如RAM的工作存储器。 应用程序更新工作存储器中的数据，然后请求提交数据，即写入外部存储设备。 作为响应，操作系统功能确定哪些数据或块已被改变并且向I / O服务提供改变的数据或块的标识，以使得I / O服务将改变的数据或块写入外部存储设备 。 因此，应用程序不负责管理I / O。 当数据从工作存储器写入外部存储设备时，操作系统允许程序继续进行其他处理。 因此，当数据写入外部存储器时，程序无需等待。 另外，由于提交过程中程序需要很少的时间，程序可以频繁地请求提交。 随着频繁提交，数据将被提交给备份存储器或备份存储（由于工作存储器的过载）提交之间的机会较少，因此无需读取时间 来自备份存储器或存储到工作存储器中的数据路由到应用程序的外部存储器。 此外，频繁提交会降低I / O子系统的超载的可能性。

    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.
