摘要： The present invention provides a virtualized computing systems and methods for transitioning in real time between LONG SUPER-MODE and LEGACY SUPER-MODE in the x86-64 architecture. In doing so, a virtual machine, which relies on the traditional 32-bit modes, i.e., REAL MODE and PROTECTED MODE (V86 SUB-MODE, RING-0 SUB-MODE, and RING-3 SUB-MODE), is able to run alongside other applications on x86-64 computer hardware (i.e., 64-bit). The method of performing a temporary processor mode context switch includes the steps of the virtual machine monitor's setting up a “virtual=real” page, placing the transition code for performing the processor mode context switch on this page, jumping to this page, disabling the memory management unit (MMU) of the x86-64 computer hardware, modifying the mode control register to set either the LONG SUPER-MODE bit or LEGACY SUPER-MODE bit, loading a new page table, and reactivating the MMU of the x86-64 computer hardware.

摘要： The present invention is a system for and method of providing instruction sequence compounding by (1) the virtual machine monitor's (VMM) looking ahead when an initial trap (exception) event occurs and recognizing traps within successive nearby instructions, combining and virtually executing the effects of multiple instructions while remaining inside the VMM's trap handler, and thereby minimizing the number of individual traps that would otherwise occur at each instruction and/or (2) the VMM's looking ahead when an initial context switch event occurs and recognizing context switches within successive nearby instructions, virtually combining the effects of multiple instructions and handing off this combined instruction to the host operating system, and thereby minimizing the number of individual context switches that would otherwise occur at each instruction. As a result, the number of processor cycles is reduced for exception handling and context switching in a virtual machine environment.

摘要： This document describes tools capable of making a portion of operating-system memory associated with a protection agent unalterable or inaccessible from an operating-system privilege mode. In some embodiments, these tools are capable of creating a protection-agent privilege mode by requesting that a virtual machine monitor protect this portion of operating-system memory. In other embodiments, these tools are capable of creating the protection-agent privilege mode by virtualizing a physical processor into multiple virtual processors, at least one of which is a protection-agent virtual processor designed to run the protection agent. By making this portion of operating-system memory unalterable or inaccessible from the operating-system privilege mode, the protection agent may be less vulnerable to attacks by entities operating within the operating-system privilege mode.
摘要翻译：本文档描述了能够使与操作系统特权模式不可更改或不可访问的保护代理相关联的操作系统内存的一部分的工具。在一些实施例中，这些工具能够通过请求虚拟机监视器保护操作系统存储器的这一部分来创建保护代理特权模式。在其他实施例中，这些工具能够通过将物理处理器虚拟化为多个虚拟处理器来创建保护代理特权模式，其中至少一个虚拟处理器是被设计为运行保护代理的保护代理虚拟处理器。通过使操作系统内存的这一部分从操作系统特权模式变得不可改变或不可访问，保护代理可能不太容易受到在操作系统特权模式下操作的实体的攻击。

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： 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 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： Various embodiments of the present invention are directed to a multi-level virtualizer that is designed to remove much of the intercept-related functionality from the base-level virtualizer (that exists outside of each partition) and, instead, incorporate much of this functionality directly into each partition. For several of the embodiments, certain intercept handling functions are performed by an “external monitor” that runs within a partition and responds to specific intercept events, and the base-level virtualizer installs these external monitors within each partition and thereafter manages the external monitors for both single-partition and cross-partition intercept events. This distributed approach to intercept handling allows for a much less complex virtualizer and moves the intercept functionality up into each partition where each external monitor uses the resources of the corresponding guest operating system in that partition to resolve the intercept event.
摘要翻译：本发明的各种实施例涉及一种多级虚拟器，其被设计为从基本级虚拟器（存在于每个分区之外）移除大部分拦截相关的功能，并且直接并入大部分功能进入每个分区。对于几个实施例，某些拦截处理功能由在分区内运行并响应特定拦截事件的“外部监视器”执行，并且基本级虚拟器在每个分区内安装这些外部监视器，然后管理外部监视器单分区和跨分区拦截事件。拦截处理的这种分布式方法允许一个不那么复杂的虚拟机，并将拦截功能移动到每个分区，每个外部监视器使用该分区中相应的客户机操作系统的资源来解决拦截事件。

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.
