摘要： Various embodiments of the present invention are directed to bimodal virtual device approaches (that is, “bimodal devices”). In certain embodiments, the bimodal device is a virtual device that is primarily based on a real piece of hardware to provide a broad degree of compatibility with software running in the guest environment (similar to the hardware device virtualization approach). However, to overcome the problem of poor performance that plague hardware virtual devices, these embodiments also provide an idealized “high-performance mode” that is not found in the original hardware-based device. Software drivers (and other software) developed for interacting with the original hardware device and which are unaware of (and unable to use) the high-performance mode will continue to use the “legacy mode” (hardware virtualization), while enhanced versions of guest software will be able to recognize and utilize the high-performance mode (idealized virtualization).

摘要： A virtual machine monitor (VMM) is configured to enforce deterministic execution of virtual machines in a multiprocessor machine. The VMM is configured to ensure that any communication by physical processors via shared memory is deterministic. When such VMMs are implemented in a distributed environment of multiprocessor machines coupled via a logical communication link, non-deterministic server applications running on virtual machines using the VMM may be replicated.

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.

摘要： Virtual machine image files are stored in a virtual machine storage by a virtual machine image file server. Users at virtual machine clients connect to the virtual machine image file server and are presented with a list of the available virtual machine image files in a virtual machine image store. Users of the virtual machine clients are able to select the desired virtual machine image, and begin executing in the selected virtual machine environment as soon as the selected virtual machine image file begins downloading to the client computer. When a virtual machine image file is selected for storage it is divided into several segments. Each segment is compared with segments of previously stored virtual machine image files already in storage. For example, only non-duplicate segments are stored.

摘要： The present invention is directed to a system for authoring and accessing computer-based materials, a high-level method of using the system, and method of saving the state and data from an authoring host onto a storage host. The system and methods employ virtual machines to save the state and data of the authoring host onto a storage host, which can then be accessed by any number of access hosts. Virtual machines are utilized to (1) save snapshots of the state of the processor and devices within the authoring host, and (2) save the data from the authoring host with differencing drives. The present invention solves a large set of problems related to inconsistencies that exist in the combinations of (a) operating systems, (b) hardware, and (c) software on computers.

摘要： The present invention is a system for and method of performing disk migration in a virtual machine environment. The present invention provides a means for quickly and easily migrating a virtual machine from one host to another and, thus, improving flexibility and efficiency in a virtual machine environment for “load balancing” systems, performing hardware or software upgrades, handling disaster recovery, and so on. Certain of these embodiments are specifically directed to providing a mechanism for migrating the disk state along with the device and memory states, wherein the disk data resides in a remotely located storage device that is common to multiple host computer systems in a virtual machine environment. The virtual machine migration process of the present invention, which includes disk data migration, occurs without the user's awareness and, therefore, without the user's experiencing any noticeable interruption.

摘要： In an exemplary embodiment, a virtual disk file can be assigned an identifier and a virtual disk files that is dependent on the virtual disk file can include a copy of the identifier. In the instance that the virtual disk file is opened and data is modified that causes the contents of a virtual disk extent to change the identifier can be changed. If the virtual disk file and the dependent virtual disk file are used to instantiate a virtual disk the difference between identifiers can be detected, which is indicative of the fact that the virtual disk may be corrupted. Other techniques are described in the detailed description, claims, and figures that form a part of this document.

摘要： Virtualization of features present on a general-purpose computing device in order to expand the use of a fixed-function device, such as a game console, into a general-purpose application platform. Hardware capabilities are virtualized in order to run a general-purpose operating system on a fixed-function device that typically lacks physical implementations of those hardware capabilities. The operating system runs using the virtualized capabilities, and existing applications are run in the environment provided by the operating system. Thus, a fixed-function device can be used to run ordinary, existing application software.

摘要： Enhanced shadow page table algorithms are presented for enhancing typical page table algorithms. In a virtual machine environment, where an operating system may be running within a partition, the operating system maintains it's own guest page tables. These page tables are not the real page tables that map to the real physical memory. Instead, the memory is mapped by shadow page tables maintained by a virtualing program, such as a hypervisor, that virtualizes the partition containing the operating system. Enhanced shadow page table algorithms provide efficient ways to harmonize the shadow page tables and the guest page tables. Specifically, by using tagged translation lookaside buffers, batched shadow page table population, lazy flags, and cross-processor shoot downs, the algorithms make sure that changes in the guest pages tables are reflected in the shadow page tables.
