摘要： A method for managing memory in a virtual computing system is provided. The method comprises providing updated monitor data for a plurality of data domains in the virtual computing system and determining based upon the updated monitor data provided whether there is a memory constraint in a memory of the virtual computing system. Further, the method comprises calculating based upon the updated monitor data, when the memory constraint is determined, a total release-amount of the memory that is to be released by the virtual computing system in order to relieve the memory constraint and issuing a notification to release the total release-amount of the memory in order to relieve the memory constraint. The method further comprises assessing based upon the updated monitor data, when the memory constraint is ended, a reuse-amount that can be reused by the plurality of virtual guests.

摘要： An application program interface for handling full-screen input/output (I/O) operations of a display device in an information handling system, such as a computer system running one or more application programs in conjunction with an operating system. The application program interface first determines characteristics of the display device in response to a request from an application program prior to performing a full-screen I/O operation, and provides these characteristics to the application program so that the application program can provide a buffer, and if an output is to be performed, construct a valid data stream for the display device. Then the application program interface builds a parameter list in response to a request from an application program to actually perform the full-screen I/O operation. Next, in response to the parameter list, the application program interface generates instructions to process the full-screen I/O operation and coordinate this request with other requests made by other application programs. The application program interface then passes the generated instructions to a control program of the information handling system to perform the desired full-screen I/O operation, and handles any status information resulting from the I/O operation. In this manner, the application program interface provides a means for allowing an application programmer to write an application program without being concerned with low level detail of a full-screen I/O operation, as well as providing a means for coordinating full-screen I/O use of a display device by several application programs in an information handling system, and a means for allowing an application program to be architecture independent with respect to full-screen I/O operation.

摘要： A technique for utilizing resources in a virtual machine operating system. The virtual machine operating system comprises a multiplicity of virtual machines. A share of resources is allocated to each of the virtual machines. Utilization by one of the virtual machines of the resources allocated to the one virtual machine is automatically monitored. If the one virtual machine needs additional resources, the one virtual machine is automatically cloned. The clone is allocated a share of the resources taken from the shares of other of the virtual machines, such that the resultant shares allocated to the one virtual machine and the clone together are greater than the share allocated to the one virtual machine before the one virtual machine was cloned. The clone performs work with its resources that would have been performed by the one virtual machine if not for the existence of said clone.
