    摘要： A host operating system can take ownership of a device. The host can project the presence of a device proxy (VDP) into a guest operating system. The VDP provides a set of device functions corresponding to the particular device class. Interactions with the VDP in the guest are forwarded to a Virtual Service Provider (VSP) in the host. The VSP maps a set of device class functions onto physical devices through a hardware abstraction and emulation layer. Functions supported directly by a physical device can be delivered to the device by the hardware abstraction layer (HAL). Functions not directly supported can be implemented through the hardware emulation layer (HEL). A uniform and robust set of functions may be made available in the guest regardless of hardware changes in the host, migration to a new host, or use of the device by other competing operating systems.

    摘要： Embodiments of the present invention pertain to an apparatus that provides four simultaneous ion and neutral measurements as a function of altitude with variable sensitivity for neutral atmospheric species. The variable sensitivity makes it possible to extend the measurements over the altitude range of 100 to more than 700 kilometers. The four instruments included in the apparatus are a neutral wind-temperature spectrometer, an ion-drift ion-temperature spectrometer, a neutral mass spectrometer, and an ion mass spectrometer. The neutral wind-temperature spectrometer and ion-drift ion-temperature spectrometer are configured to separate O and N2 and O+ from H+ while the neutral mass spectrometer and the ion mass spectrometer are configured to separate mass with a resolution of one in sixty-four to enable metallic ion identification in the lower thermosphere. The energy analyzer features of the wind-temperature spectrometer and ion-drift ion-temperature spectrometer also enable the measurement of the thermosphere-to-exosphere transition in the Earth's upper atmosphere.

    摘要： A catch-up mode that runs a virtual programmable interrupt timer faster than a nominal rate to prevent time loss in a virtual machine can be implemented. If time loss is determined, a catch-up mode can be initiated to cause increased firings, beyond a nominal rate, of the programmable interrupt timer to adjust the clock of the virtual machine to the clock of the host system. The virtual programmable interrupt timer can also be readjusted to a predetermined nominal rate when the time loss in the guest operating system is determined approximately within a predetermined tolerance range. The catch-up mode can be monitored to avoid “interrupt storms” on the virtual machine. The virtual programmable interrupt timer can be altered by the guest operating system to accommodate different operating systems.

    摘要： One or more virtual processors can be added or removed from a virtual machine based on CPU pressure measured within the virtual machine. In addition to the foregoing, CPU pressure can also be used to determine whether to remove a virtual processor from a virtual machine, which may cause the computer system to consume less power. In the alternative, virtual processors can be parked and/or unparked in order to reduce the amount of power consumed by the virtual machine. In addition, virtual processors can be forcibly parked during a migration operation.

    摘要翻译： 可以根据在虚拟机内测量的CPU压力从虚拟机添加或移除一个或多个虚拟处理器。 除了上述之外，还可以使用CPU压力来确定是否从虚拟机移除虚拟处理器，这可能导致计算机系统消耗较少的功率。 在替代方案中，可以将虚拟处理器停放和/或未停机，以便减少虚拟机消耗的功率量。 此外，虚拟处理器可以在迁移操作期间被强制停放。
