    摘要: A host computing device has a virtual machine (VM) instantiated thereon. The VM has a virtual application instantiated thereon and a virtual processor. The host also has a virtual machine monitor (VMM) instantiated thereon to oversee the VM and to intercept instructions from a virtual entity comprising one of the virtual application and the VM to the virtual processor of such VM. The virtual entity becomes self-aware of the virtual status thereof based on a self-aware flag as obtained from the VMM, and based thereon obtains particular virtual metadata from a Synthetic range of the virtual processor by way of the VMM to operate efficiently. The Synthetic range of the virtual processor is implemented by the VMM and does not correspond to any defined range of the physical processor corresponding to the virtual processor.

    摘要: Sharing access to resources using an inter-process communication (“IPC”) provides a connection in which references to resources are passed from a sender to a receiver in a trusted third party environment. A sender in possession of a reference to a resource, such as a handle to an object, may initiate the connection with the receiver. In turn, the receiver may accept or refuse the connection, and may further specify the types of resources in which the receiver is interested when accepting through the connection. Sharing access to resources in this manner advantageously insures that only a process that already has access to a resource is able to share that access with another process, and further that only processes that wish to do so will accept such access.
