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： A method of managing resources in a host computer includes generating a virtual service provider in two different computer partitions and linking them in a serial manner. The virtual service providers are associated with a computer resource. Virtual service clients in different partitions may use the virtual service provider software to access the related computer resources. The virtual service providers provide a transparent interface to the associated hardware. Virtual service clients can use the combination of series computer resource functions or can access the a lesser number of the series connected virtual service providers. Fault tolerance can be built into the scheme using multiple virtual service providers located in different partitions accessible to virtual service clients using a failover control technique.
摘要翻译：管理主计算机中的资源的方法包括在两个不同的计算机分区中生成虚拟服务提供商，并以串行方式链接它们。虚拟服务提供商与计算机资源相关联。不同分区中的虚拟服务客户机可能会使用虚拟服务提供商软件来访问相关的计算机资源。虚拟服务提供商提供对相关硬件的透明接口。虚拟服务客户端可以使用系列计算机资源功能的组合，也可以访问较少数量的连接的虚拟服务提供商。使用故障切换控制技术的虚拟服务客户机可访问的不同分区中的多个虚拟服务提供商可以将容错内置到该方案中。

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 method for performing a write operation to a hard drive or other memory space is provided. The hard drive is represented as at least two files. The first file is a parent drive and includes some content of the hard drive. Writes made to the hard drive are recorded in a second file, known as a differencing drive. Because no changes are made to the content of the parent drive, the content of the hard drive may be rolled back to the content of the parent drive by discarding the differencing drive.

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： 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： 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. During the period that the hypervisor is coupled to the processor, the page table of the hypervisor is established such that it largely mirrors the page table of the guest operating system. If a change to the page table of the guest operating system causes a conflict between the page table of the guest operating system and the page table of the hypervisor, the page table of the hypervisor is reallocated in a manner that is transparent to the guest operating system.
摘要翻译：在仿真的计算环境中，提供了一种用于相对于处理器的某些处理器设置将主机操作系统与计算机系统的处理器逻辑去耦的方法。仿真程序的虚拟机管理程序用与客户机操作系统提供的软件例程或数据结构相关联的处理器设置替代处理器的一些处理器设置。已更换的处理器设置将写入存储器。在此期间，当处理器调用软件程序或访问与替换的处理器设置相关联的数据结构时，处理器将呼叫或访问软件程序或访问与客户操作系统相关联的数据结构，绕过主机操作系统，以及与客户操作系统直接通信。当主机操作系统要重新连接到处理器时，已经保存到存储器的处理器设置被重写到处理器的相应寄存器。在管理程序耦合到处理器的期间，管理程序的页表被建立，使得它很大程度上反映客户操作系统的页表。如果对客户操作系统的页表的更改导致客户机操作系统的页表和虚拟机管理程序的页表之间的冲突，则虚拟机管理程序的页表以对客户操作透明的方式重新分配系统。

摘要： A method for monitoring and emulating privileged instructions of a program that is being executed at a privilege level in a virtual machine is disclosed. A privilege level associated with a received instruction is determined. The instruction privilege level is compared to the program execution privilege level. If the instruction privilege level is valid with respect to the program execution privilege level, the instruction is executed. If the instruction privilege level is invalid with respect to the program execution privilege level: the instruction result is emulated; the number of times the instruction has been received from the program is checked; and if the instruction has been received more than a specified number of times, the instruction is overwritten with one or more instructions with a valid privilege level with respect to the program execution privilege level.
