摘要： Systems and methods are provided, whereby partitions may become enlightened and discover the presence of a hypervisor. Several techniques of hypervisor discovery are discussed, such as detecting the presence of virtual processor registers (e.g. model specific registers or special-purpose registers) or the presence of virtual hardware devices. Upon discovery, information (code and/or data) may be injected in a partition by the hypervisor, whereby such injection allows the partition to call the hypervisor. Moreover, the hypervisor may present a versioning mechanism that allows the partition to match up the version of the hypervisor to its virtual devices. Next, once code and/or data is injected, calling conventions are established that allow the partition and the hypervisor to communicate, so that the hypervisor may perform some operations on behalf of the partition. Four exemplary calling conventions are considered: restartable instructions, a looping mechanism, shared memory transport, and synchronous or asynchronous processed packets. Last, cancellation mechanisms are considered, whereby partition requests may be cancelled.

摘要： An operating system is described that is capable of ascertaining whether it is executing in a virtual machine environment and is further capable of modifying its behavior to operate more efficiently and provide optimal behavior in a virtual machine environment. An operating system is enlightened so that it is aware of VMMs or hypervisors, taking on behavior that is optimal to that environment. The VMM or hypervisor informs the operating system of the optimal behavior, and vice versa.

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.
