摘要： A subject disclosure is directed towards emulating a data network interface for operating an interconnect controller in accordance with a networking standard. The emulated data network interface provides address resolution data associated with a destination, within a converged interconnect fabric, for application data. The address resolution data identifies a communication path that is compatible with the interconnect controller. The application data conforms to the networking standard. The emulated data network interface instructs the interconnect controller to route the application data to the destination via the compatible communication path.

摘要： There is provided a method of providing a template virtual machine. An exemplary method comprises creating a template virtual machine comprising an image of an operating system and software running on the operating system. The template virtual machine does not include machine-specific identifiers. The template virtual machine is booted into a virtual machine environment. Subsequently, machine-specific identifiers for the template virtual machine are updated. The template virtual machine may then be booted with machine-specific identifiers into a service instance to perform a function determined by the software running on the operating system such that uniform code pages representing the operating system and software running on the operating system are shared among virtual machines in the virtual machine environment.

摘要： Different processor cores in a computing device can support different features. In one or more embodiments, the features supported by each of multiple physical processor cores of a computing device are identified. A set of one or more features of the multiple physical processor cores to make available to virtual processor cores of the virtual machine are determined based at least in part on both the one or more features supported by each of the multiple physical processor cores and a number of virtual processor cores of the virtual machine. In additional embodiments, a multi-level scheduling model is used. An operating system level scheduler of an operating system schedules multiple applications for execution on multiple processor cores, and a user level scheduler of an application schedules application threads of that application for execution on one or more of the multiple processor cores.

摘要： Embodiments for performing directed switches between user mode schedulable (UMS) thread and primary threads are disclosed. In accordance with one embodiment, a primary thread user portion is switched to a UMS thread user portion so that the UMS thread user portion is executed in user mode via the primary thread user portion. The primary thread is then transferred into kernel mode via an implicit switch. A kernel portion of the UMS thread is then executed in kernel mode using the context information of a primary thread kernel portion.

摘要： Performing directed switches between user mode schedulable (UMS) threads and primary threads enable proper execution of the UMS threads. A primary thread user portion is switched to a UMS thread user portion so that the UMS thread user portion is executed in user mode via the primary thread user portion. The primary thread is then transferred into kernel mode via an implicit switch. A kernel portion of the UMS thread is then executed in kernel mode using the context information of a primary thread kernel portion.
