摘要： Various mechanisms are disclosed herein for the saving and restoring of virtual machine environment state. For example, virtual machine state can be either be saved or (multiple) snapshots can be taken of the virtual machine state. In the latter case, virtual processors can be allowed to run while the memory of the virtual machine state is being saved. In either case, virtual devices associated with the virtual machine environment can be quiesced such that these devices can prepare themselves to be saved. Once such virtual devices and memory are saved, they can also be restored. For example, restoration of memory can occur while virtual processors are running at the same time. And, moreover, restoration can occur in batches of pages, thus optimizing the response time for restoring saved data.
摘要翻译：本文公开了用于保存和恢复虚拟机环境状态的各种机制。例如，可以保存虚拟机状态，或者可以采用虚拟机状态的（多个）快照。在后一种情况下，可以允许虚拟处理器在虚拟机状态的存储器被保存时运行。在任一种情况下，与虚拟机环境相关联的虚拟设备都可以停顿，以便这些设备可以准备好自己保存。一旦这样的虚拟设备和内存被保存，它们也可以恢复。例如，当虚拟处理器同时运行时，可能会发生内存的恢复。而且，还可以批量进行页面恢复，从而优化恢复保存的数据的响应时间。

摘要： Provided are optimizations to the memory virtualization model employed in a virtual machine environment. An opportunistic hypervisor page mapping process is used in order to utilize large memory pages in a virtual machine environment. Using these optimizations, physical memory is being virtualized for the virtual machine in a manner that allows the operating system (OS) running within the virtual machine to take real and full advantage of large physical memory pages.

摘要： Systems and methods for enabling trusted software to monitor and control USB traffic associated with a security extension of a host controller and devices in a USB topology is disclosed. A host controller proxy receives USB-related data from a host controller driver, determines whether the data is of a security interest, and if so, sends the data to a driver for a security extension executing in the trusted execution environment. Likewise, after software executing in the trusted execution environment evaluates and appropriately addresses data sent by the HCD proxy or data retrieved from a hardware security extension, the HCD proxy receives data from the trusted execution environment for further dissemination.

摘要： A method for managing software modules of at least two operating systems sharing physical resources of a computing environment, but running in different partitions separated by a virtualization boundary comprises accumulating module information in a virtualization subsystem that directs the creation and management of the partitions. The accumulated module information is used across the virtualization boundary to manage the use of the software modules. Also, a method for managing software modules comprises making at least two operating systems aware that they are being hosted in a virtualized computing environment.

摘要： Techniques are disclosed to provide security for graphical user interface elements being displayed in a system having a host operating system and a high assurance operating system. Graphical user interface elements associated with the high-assurance operating system may be prevented from being obscured and from any partial transparency. Additionally, a piece of secret information may be stored and displayed by graphical user interface elements associated with the high-assurance operating system. Coordinating certain elements of the graphical user interface elements associated with the high assurance operating system also helps to identify legitimate elements associated with the high assurance operating system. Public title information may be furnished to a host operating system windowing system to identify a window owned by a process running on a high-assurance operating system. Private title information associated with the same window may be used in the high assurance operating system.

摘要： Techniques are disclosed to provide security for user input in which a first, host operating system is used along with a second, high assurance operating system, where the first system provides at least some of the infrastructure for the second system. Two modes are presented. In a first mode, user data is passed to the host operating system. In a second mode, user data is retained in the second operating system for the use of the second operating system or processes running on the second operating system. Transitions between the nodes can be accomplished according to hypothecated user actions such as keystroke combinations, or when the user performs an action which indicates a programmatic activation of a process running in the second operating system. Where shadow graphical elements are run by the first operating system to indicate the location of graphical elements from processes running on the second operating system, this programmatic activation may be indicated by programmatic activation of a shadow graphical element.
摘要翻译：公开了技术来为用户输入提供安全性，其中第一主机操作系统与第二高保证操作系统一起使用，其中第一系统为第二系统提供至少一些基础设施。提出了两种模式。在第一模式中，用户数据被传递到主机操作系统。在第二模式中，用户数据被保留在第二操作系统中，以便使用在第二操作系统上运行的第二操作系统或进程。节点之间的转换可以根据诸如按键组合之类的假设的用户动作，或当用户执行指示在第二操作系统中运行的进程的编程激活的动作时完成。在阴影图形元素由第一操作系统运行以指示来自在第二操作系统上运行的进程的图形元素的位置的情况下，可以通过阴影图形元素的编程激活来指示该程序化激活。
