Abstract: The current document is directed to methods and systems for monitoring the performance of memory management in virtual machines. By accurately measuring the performance of memory management in virtual machines, a virtualization layer can dynamically reconfigure virtual machines to use more optimal memory-management methods, intelligently schedule execution of virtual machines to increase memory-management performance, and migrate virtual machines among different servers and computer systems to increase memory-management performance.

Abstract: The current document is directed to virtualized PMUs provided by virtualization layers. The currently disclosed virtualized PMUs are decoupled from the underlying PMU hardware features of processors on which the virtualization layer executes. The decoupling is achieved, in part, by time multiplexing the underlying hardware PMU registers to provide a greater number of virtualized PMU registers than the number of hardware-PMU registers provided by at least some of the underlying hardware PMUs. The decoupling is also achieved by providing for monitoring, by the virtualized PMU registers, of computed processor events and approximated processor events in addition to the processor events monitored by the underlying hardware PMUs. In addition, the virtualized PMU registers are implemented, in certain implementations, to support a variety of different monitoring modes, including monitoring of processor events that occur only during execution of the virtualization layer and monitoring of hardware-thread-specific processor events.
Abstract translation: 当前文档针对虚拟化层提供的虚拟化PMU。 目前公开的虚拟化PMU与虚拟化层执行的处理器的底层PMU硬件特征分离。 解耦是部分地通过时间复用底层硬件PMU寄存器来实现的，以提供比由至少一些底层硬件PMU提供的硬件PMU寄存器的数量更多的虚拟化PMU寄存器。 还可以通过虚拟化PMU寄存器监视计算的处理器事件和近似处理器事件以及底层硬件PMU监控的处理器事件之外的其他方式实现去耦。 此外，在某些实现中，虚拟化PMU寄存器被实现以支持各种不同的监视模式，包括监视仅在执行虚拟化层期间发生的处理器事件以及监视硬件线程特定处理器事件。
