摘要： There is a need for providing the Xeon CPU with a two-level VM that is independent of VMM types and prevents the throughput from degrading when the OS operates the privilege register. A machine is provided with a processor and memory. The machine includes a first virtual machine manager for managing a virtual machine, a second virtual machine for managing an operating system, first management information, and second management information. The processor is provided with a register and a shadowing function. The machine uses a virtualization method. The first virtual machine manager detects a call from the second virtual machine manager. The first virtual machine manager enables the shadowing function when it is determined that an instruction for enabling the shadowing function caused the call.

摘要： In one embodiment of the invention, the exit and/or entry process in a nested virtualized environment is made more efficient. For example, a layer 0 (L0) virtual machine manager (VMM) may emulate a layer 2 (L2) guest interrupt directly, rather than indirectly through a layer 1 (L1) VMM. This direct emulation may occur by, for example, sharing a virtual state (e.g., virtual CPU state, virtual Device state, and/or virtual physical Memory state) between the L1 VMM and the L0 VMM. As another example, L1 VMM information (e.g., L2 physical to machine address translation table) may be shared between the L1 VMM and the L0 VMM.

摘要翻译： 在本发明的一个实施例中，嵌套虚拟化环境中的出口和/或进入过程更有效。 例如，层0（L0）虚拟机管理器（VMM）可以直接模拟层2（L2）客户中断，而不是间接地通过层1（L1）VMM。 这种直接仿真可以通过例如在L1 VMM和L0 VMM之间共享虚拟状态（例如，虚拟CPU状态，虚拟设备状态和/或虚拟物理存储器状态）而发生。 作为另一示例，L1 VMM信息（例如，L2物理到机器地址转换表）可以在L1 VMM和L0 VMM之间共享。

摘要： In a logically partitioned host computer system comprising host processors (host CPUs), a facility and instruction for discovering topology of one or more guest processors (guest CPUs) of a guest configuration comprises a guest processor of the guest configuration fetching and executing a STORE SYSTEM INFORMATION instruction that obtains topology information of the computer configuration. The topology information comprising nesting information of processors of the configuration and the degree of dedication a host processor provides to a corresponding guest processor. The information is preferably stored in a single table in memory.

摘要： Embodiments of apparatuses and methods for processing virtualization events in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes a event logic and evaluation logic. The event logic is to recognize a virtualization event. The evaluation logic is to determine whether to transfer control from a child guest to a parent guest in response to the virtualization event.

摘要： A computer system that has a machine unit of operation (MUO) used to time executions in the system, has a User State and a Control State, has multiple domains for logical processors, and and has a Domain Unit of Operation (DUO) to time domain operations in the system. The DUO is used for timing during emulation User instructions a control program in control state. The physical processor is augmented by a DUO control bit that control bit indicates that execution is within a machine unit of operation or a domain unit of operation. The DUO bit is set when a transfer is forced from User State to Control State in order to emulate a user instruction. The DUO bit can be explicitly set or reset by Control Software.

摘要： A computer system including a processor and memory, the processor having a virtual mode of operation in which it uses a virtual machine monitor which allows it to service a plurality of users contemporaneously in a multiplexed manner, and a non-virtual, or real, mode of operation. The computer system has a set of at least three operation mode protection rings representing a hierarchy of access privilege levels in both the real and virtual modes, with the number of privilege levels in both the real and virtual modes being the same. The privilege levels govern the accessibility of memory locations to programs and the executability of certain privileged instructions, which cause control to be transferred to the virtual machine monitor when the processor is in a virtual mode. The two most privileged levels in the virtual mode are both treated as corresponding to the second most privileged level in the real mode, whereby if the processor is in the most privileged virtual operating mode, access to memory locations is permitted only if the location is accessible to the second most privileged mode. When an instruction is retrieved, the processor first performs a probe operation to determine whether it can access any required memory locations in response to its current privilege level, and then determines whether it is in a privilege level which allows it to process the instruction.

摘要： A processing system includes a first register to store an invalidation mode flag associated with a virtual processor identifier (VPID) and a processing core, communicatively coupled to the first register, the processing core comprising a logic circuit to execute a virtual machine monitor (VMM) environment, the VMM environment comprising a root mode VMM supporting a non-root mode VMM, the non-root mode VMM to execute a virtual machine (VM) identified by the VPID, the logic circuit further comprising an invalidation circuit to execute a virtual processor invalidation (INVVPID) instruction issued by the non-root mode VMM, the INVVPID instruction comprising a reference to an INVVPID descriptor that specifies a linear address and the VPID and responsive to determining that the invalidation mode flag is set, invalidate, without triggering a VM exit event, a memory address mapping associated with the linear address.
