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.
