Abstract: Mechanisms are disclosed herein that manage operations in virtual machine environments. A first partition can have a proxy driver object corresponding to a driver object in a second partition. The driver object can control a physical device, but because of the proxy driver object, the first partition can retain some measure of control over the physical device. The driver object can be surrounded by a first filter object beneath it, and a second filter object above it. The first filter object can provide interfaces to the driver object so that the driver object can perform various bus-related functionalities; and, the second filter object can receive redirected instructions from the first partition and provide them to the driver object, and intercept any instructions originating from within the second partition, such that if these instructions are inconsistent with policies set in the first partition, they can be manipulated.

Abstract translation: 本文公开了管理虚拟机环境中的操作的机制。 第一个分区可以具有与第二个分区中的驱动程序对象相对应的代理驱动程序对象。 驱动程序对象可以控制物理设备，但是由于代理驱动程序对象，第一个分区可以保留对物理设备的一些控制措施。 驱动程序对象可以被它下面的第一个过滤器对象包围，并在其上方有一个第二个过滤器对象。 第一个过滤器对象可以向驱动程序对象提供接口，使得驱动程序对象可以执行各种总线相关的功能; 并且所述第二过滤器对象可以从所述第一分区接收重定向的指令并将其提供给所述驱动对象，并拦截源自所述第二分区内的任何指令，使得如果所述指令与所述第一分区中设置的策略不一致，则它们可以 被操纵。
