摘要： Several embodiments of the present invention provide a means for improving data access security in computer systems to support high-security applications, and certain of these embodiments are specifically directed to providing sector-level encryption of a virtual hard disk in a virtual machine environment. More specifically, certain embodiments are directed to providing sector-level encryption by using plug-ins in a virtual machine environment, thereby providing improved data access security in a computer system that supports high-security applications. Certain embodiments also use encryption plug-ins associated with standard encryption software for exchanging data between a virtual machine (VM) and its associated virtual hard drive(s) (VHDs). Moreover, several embodiments of the present invention are directed to the use of plug-in encryption services that interface with, and provide services for, a VM via a VM Encryption API (or its equivalent).

摘要： A method and system are provided for integrating partitions in a virtual machine environment. Specifically, a partition bus is provided, where the partition bus operatively connects partitions in such a way that it functions as a data transport mechanism allowing for data transfer and device sharing between partitions. The partition bus relies on virtualizing software in order to establish itself and to establish channels of communication between partitions and to inject interrupts to partitions where it is appropriate to do so. Furthermore, the partition bus employs such mechanisms ring buffers, transfer pages, and memory map changes to transfer information (requests and data). Furthermore, it uses policy agents to decide when information should be transferred or when devices should be shared among partitions. Lastly, it employs various mechanisms to ensure smooth integration between partitions, which includes remote services that have proxy devices and device versioning functionalities.

摘要： A method of virtualizing memory through shadow page tables that cache translations from multiple guest address spaces in a virtual machine includes a software version of a hardware tagged translation look-aside buffer. Edits to guest page tables are detected by intercepting the creation of guest-writable mappings to guest page tables with translations cached in shadow page tables. The affected cached translations are marked as stale and purged upon an address space switch or an indiscriminate flush of translations by the guest. Thereby, non-stale translations remain cached but stale translations are discarded. The method includes tracking the guest-writable mappings to guest page tables, deferring discovery of such mappings to a guest page table for the first time until a purge of all cached translations when the number of untracked guest page tables exceeds a threshold, and sharing shadow page tables between shadow address spaces and between virtual processors.
摘要翻译：通过影像页表虚拟化存储器的方法，其缓存来自虚拟机中的多个访客地址空间的转换，包括硬件标记的翻译后备缓冲器的软件版本。通过拦截向客户页面表创建客户机可写映射，并通过缓存在阴影页表中的翻译来检测访客页面表的编辑。受影响的缓存翻译被标记为陈旧，并被清除在地址空间开关或客人不加区别地翻译翻译。因此，非陈旧的翻译仍保持高速缓存，但是陈旧的翻译将被丢弃。该方法包括跟踪访客页面表的访客可写映射，将此类映射的发现推迟到访客页面表，直到当未跟踪的访客页面表的数量超过阈值时清除所有缓存的翻译，并共享阴影阴影地址空间和虚拟处理器之间的页表。

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： In an emulated computing environment, a method is provided for logically decoupling the host operating system from the processor of the computer system with respect to certain processor settings of the processor. A hypervisor of the emulation program replaces some of the processor settings of the processor with processor settings associated with software routines or data structures provided by the guest operating system. The replaced processor settings are written to memory. During this period, when the processor calls a software routine or accesses a data structure associated with the replaced processor setting, the processor will call or access a software routine or access a data structure associated with the guest operating system, bypassing the host operating system and communicating directly with the guest operating system. When the host operating system is to be recoupled to the processor, the processor settings that have been saved to memory are rewritten to the appropriate registers of the processor.

摘要： A method for processing software instructions in an emulated computing environment is provided in which instruction blocks from the application programs of a guest computer system are parsed to determine whether the instruction blocks include instructions executable at user level or supervisor level. Those instruction blocks that are executable at user level are passed directly to the processor of the host computer system, and those instruction blocks that are executable at supervisor level, are translated before being passed to the processor for execution. In the case of instruction blocks that include instruction blocks executable at supervisor level, prior to translation, a cache is queried to determine whether a translation for the instruction block is in the case. If a translation is in the cache, the translated version in the cache is provided to the processor for execution. If a translation is not in the cache, translation occurs, and the translated instruction block is saved to the cache.
