摘要： In some embodiments, the invention efficiently manages, sets up, controls and performs communication between isolated components using portals. In a platform having virtualization architecture, a component in a first virtual machine requests a service to be performed by a component in a second virtual machine. A privileged system layer validates the ability to create a communication portal between the two components. The validation is a two-level validation to ensure that a portal is permitted between the two components and that the requested activity is also permitted. Other embodiments are described and claimed.
摘要翻译：在一些实施例中，本发明使用门户有效地管理，建立，控制和执行隔离组件之间的通信。在具有虚拟化架构的平台中，第一虚拟机中的组件请求由第二虚拟机中的组件执行的服务。特权系统层验证了在两个组件之间创建通信门户的能力。验证是一个两级验证，以确保两个组件之间允许门户，并且还允许所请求的活动。描述和要求保护其他实施例。

摘要： A system and method for allowing a virtual machine monitor to assume control of a system when the current privilege level of guest software meets a privilege level exiting criteria. The processor detects that the current privilege level meets the criteria and then transfers control from the guest software to the virtual machine monitor. The virtual machine monitor may decline to assume control for certain privilege level changes or values.

摘要： A method of reconfiguring a stream process in a distributed system includes the initial step of managing a stream process including one or more operators. The one or more operators are communicatively associated with one or more stream targets. The one or more operators use a partition function to determine the routing of messages to the one or more stream targets. The method includes the steps of determining a safe state within the stream process, and configuring a configuration state of the one or more operators during the safe state.

摘要： A method for caching of page translations for virtual machines includes managing a number of virtual machines using a guest page table of a guest operating system, which provides a first translation from a guest-virtual memory address to a first guest-physical memory address or an invalid entry, and a host page table of a host operating system, which provides a second translation from the first guest-physical memory address to a host-physical memory address or an invalid entry, and managing a cache page table, wherein the cache page table selectively provides a third translation from the guest-virtual memory address to the host-physical memory address, a second guest-physical memory address or an invalid entry.

摘要： A method of achieving fault tolerance in a distributed stream processing system organized as a directed acyclic graph includes the initial step of managing a stream process within the distributed stream processing system including one or more operators. The one or more operators of the stream process are communicatively associated with one or more downstream operators. The method includes the steps of maintaining one or more data copies of a processing state of the one or more operators until the one or more data copies can be safely discarded, notifying the one or more operators when it is safe to discard at least one of the at least one of the one or more data copies of the processing state; and using an identifier to denote the data copy of the processing state to be safely discarded.
