摘要： An installation package associated with an application is obtained. Installation of the application in a first type of system is analyzed based at least in part on the installation package. A first set of changes made to the first type of system resulting from installation of the application in the first type of system is identified. Based on the first set of changes, a second set of changes made to a second type of system resulting from installation of the application in the second type of system is identified, and a recipe identifying the second set of changes is generated. A new installation package associated with the application can also be generated. This new installation package is configured for installation of the application on the second type of system, and is based at least in part on both the recipe and the installation package.

摘要： A method and system are provided for integrating partitions in a virtual machine environment. Specifically, a partition bus is provided, where the partition bus operatively connects partitions in such a way that it functions as a data transport mechanism allowing for data transfer and device sharing between partitions. The partition bus relies on virtualizing software in order to establish itself and to establish channels of communication between partitions and to inject interrupts to partitions where it is appropriate to do so. Furthermore, the partition bus employs such mechanisms ring buffers, transfer pages, and memory map changes to transfer information (requests and data). Furthermore, it uses policy agents to decide when information should be transferred or when devices should be shared among partitions. Lastly, it employs various mechanisms to ensure smooth integration between partitions, which includes remote services that have proxy devices and device versioning functionalities.

摘要： A method of virtualizing memory through shadow page tables that cache translations from multiple guest address spaces in a virtual machine includes a software version of a hardware tagged translation look-aside buffer. Edits to guest page tables are detected by intercepting the creation of guest-writable mappings to guest page tables with translations cached in shadow page tables. The affected cached translations are marked as stale and purged upon an address space switch or an indiscriminate flush of translations by the guest. Thereby, non-stale translations remain cached but stale translations are discarded. The method includes tracking the guest-writable mappings to guest page tables, deferring discovery of such mappings to a guest page table for the first time until a purge of all cached translations when the number of untracked guest page tables exceeds a threshold, and sharing shadow page tables between shadow address spaces and between virtual processors.

摘要： Multiple software component identifiers are maintained in a catalog of an operating system running on a device. Each of these software component identifiers corresponds to one of multiple software components installed on the device. The catalog is accessed in response to a request regarding one of the multiple software components, and the request is responded to based at least in part on information included in the catalog. Additionally, two or more versions of a software component that are installed on the computing device can be identified. Which one of the two or more versions of the software component is an active version of the software component to be run is determined. In response to requests for information regarding the software component, information regarding the active version of the software component is returned.

摘要： Various operations are disclosed for improving the operational efficiency of interrupt handling in a virtualized environment. A virtualized interrupt controller may obviate the need for an explicit end-of-interrupt command by providing an automatic EOI capability even when a physical interrupt controller offers no such mechanism. The use of a message pending bit for inter-partition communications facilitates avoiding an EOI command of inter-processor interrupts used in inter-partition communications whenever no further messages are cued for a particular message slot. A virtualized interrupt controller facilitates the selective EOI of an interrupt even when it is not the highest priority in-service interrupt irrespective of whether a physical interrupt controller provides such functionality.

摘要： Provided are optimizations to the memory virtualization model employed in a virtual machine environment. An opportunistic hypervisor page mapping process is used in order to utilize large memory pages in a virtual machine environment. Using these optimizations, physical memory is being virtualized for the virtual machine in a manner that allows the operating system (OS) running within the virtual machine to take real and full advantage of large physical memory pages.

摘要： An operating system is described that is capable of ascertaining whether it is executing in a virtual machine environment and is further capable of modifying its behavior to operate more efficiently and provide optimal behavior in a virtual machine environment. An operating system is enlightened so that it is aware of VMMs or hypervisors, taking on behavior that is optimal to that environment. The VMM or hypervisor informs the operating system of the optimal behavior, and vice versa.
