    摘要: A mechanism is provided for making information about the virtual disk image file and/or its associated virtual image configuration file more readily available to a user. The virtual disk image file format is expanded to include fields in which information about the data in the file can be stored. Extensible information on file content, compatible HW configurations, compatible host OSes, timeout status, DRM status, patch state, and network topology, tag data for indexing, configuration files, saved state files, operation history data, and the like is stored in a location within a virtual disk image file that can be read without executing the virtual machine. This information can then be used to search the contents of the virtual disk image, to enforce usage policies, to provide extensibility for vendors, and the like.

    摘要: A computer system and method for communicating in a virtual environment. The computer system may include a first partition and a virtual service client implemented at a first position in the first partition. The computer system may also include a second partition, and a virtual service provider implemented at a second position in the second partition. The first partition and the second partition may be in operative communication via the virtual service client and the virtual service provider. The first position and the second position may enable the virtual service client and the virtual service provider to reduce processing overhead associated with communicating in the virtual environment by eliminating a processing step, a buffer copy, a software interrupt, and/or a context switch.

    摘要: In exemplary embodiments, device capabilities, i.e., functions performed in a hardware device, can be selectively enabled/disabled in a virtual machine by modifying configuration information for a hardware device emulator. For example, the configuration information can be changed in order to cause a guest operating system to load a specific device driver that enables/disables select hardware capabilities in a virtual machine. Other techniques are described in the claims, detailed description, and drawings.

    摘要: A method of agreeing on the utilization of at least one computer resource between two virtual machines includes sending a first resource request by a first virtual machine to a second virtual machine having computer resources to allocate to the first virtual machine. The second virtual machine responds by sending at least one available resource for use by the first virtual machine. The first virtual machine can select from the at least one available resource. Both the first and second virtual machines can then execute on the agreed resource utilization by the first virtual machine and begin using the resource. When conditions change, either the first virtual machine or the second virtual machine can request a renegotiation of the agreement to use computer resources.
