    摘要： Various aspects are disclosed herein for bounding the behavior of a non-privileged virtual machine that interacts with a device by creating a description of the device which indicates to a privileged authority (1) which operations on the device may have system-wide effects and (2) which operations have effects local to the device. The privileged authority may then permit or deny these actions. The privileged authority may also translate these actions into other actions with benign consequences.

    摘要： Various aspects are disclosed herein for replacing the hardware backing the memory locations associated with a virtual machine with a backing mechanism. The backing mechanism may have the memory locations appear to contain data convenient to the driver in the virtual machine, typically containing what the hardware would have returned if the hardware had been read from. The data image being returned from the memory locations may travel with the virtual machine even if the virtual machine moves to a different physical machine that does not contain hardware equivalent to the hardware that was recently removed from the virtual machine.

    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： The subject invention relates to systems and methods for automatic recovery from errors in a computing environment. A system is provided to facilitate failure recovery in the computing system. The system includes at least one driver component that enumerates at least one layer of a driver stack. A module associated with the driver component requests re-enumeration of the driver stack upon detection of an error in the computing system. When an error is detected by a driver or operating system component, a protocol can be established whereby a new copy of the driver's stack or system resources is re-enumerated in parallel to existing resources that may be in an unknown or error state. The new copy of the stack may allow the driver to become operational in lieu of the previous stack which can be reclaimed for other system uses over time.

    摘要： The present invention provides a unified layer for Plug and Play (PnP) components and power management components while relieving device drivers from system-level complexities associated with implementing PnP and/or power management functionality. The layer operates at a level between low-level device drivers and more complex operating system tasks. The subject invention simplifies designing device drivers having proper power management support by creating an infrastructure that allows a device driver to operate within a driver framework or model and without having to process Plug-and-Play or Power Management I/O Request Packets (IRPs) directly.
