    • Machine-readable media, methods, apparatus and system are described. In some embodiments, a client platform may determine that an input/output operation related to a hardware device may happen in a virtual machine of the client platform and request a server platform via the network to handle the input/output operation related to the hardware. The server platform may receive the request from the client platform through the network; and identify a software device from a plurality of software devices in the server platform to handle the request, wherein the identified software device corresponds to the hardware device related to the input/output operation.
    • 描述了机器可读介质,方法,装置和系统。 在一些实施例中,客户机平台可以确定与硬件设备相关的输入/输出操作可能发生在客户端平台的虚拟机中,并经由网络请求服务器平台来处理与硬件相关的输入/输出操作。 服务器平台可以通过网络从客户端平台接收请求; 并从所述服务器平台中的多个软件设备识别软件设备以处理所述请求,其中,所识别的软件设备对应于与所述输入/输出操作相关的硬件设备。

    • Methods, system and machine-readable medium are described to handle a device related operation in a virtualization environment. In some embodiment, a kernel component of a virtual machine monitor may determine that a device related operation happens in a virtual machine through a operation transition from the virtual machine to the kernel component; and may determine whether the device related operation can be handled by a first virtual hardware device installed inside of the kernel component of the virtual machine monitor. In other embodiment, the kernel components may initiate an interrupt by the first virtual hardware device; and inject the interrupt from the first virtual hardware device to the virtual machine through another operation transition from the kernel component to the virtual machine.
    • 描述了方法,系统和机器可读介质来处理虚拟化环境中与设备相关的操作。 在一些实施例中,虚拟机监视器的内核组件可以通过从虚拟机到内核组件的操作转换来确定设备相关操作发生在虚拟机中; 并且可以确定设备相关操作是否可以由安装在虚拟机监视器的内核组件内部的第一虚拟硬件设备来处理。 在另一实施例中,内核组件可以由第一虚拟硬件设备发起中断; 并通过从内核组件到虚拟机的另一个操作过渡将中断从第一个虚拟硬件设备注入虚拟机。

    • A cascade impactor apparatus has a series of vertically stacked impactor housing sections. Each of the impactor housing sections has an upper portion that supports a motor for driving an impactor plate that is positioned below a nozzle through which flow passes. Each housing section also has an outlet passageway leading to a lower impactor chamber for the next in a series of impactor chambers, except the last outlet passageway is coming through a filter to exhaust. The impactor chambers are defined by a skirt that seals on the neck of the next downstream housing section. The impactor plates are each driven by a separate motor, and held onto a hub on the motor output shaft with a magnetic coupling so the plates can be removed when the housings are separated.
    • 级联冲击器装置具有一系列垂直堆叠的冲击器容纳部分。 每个冲击器容纳部分具有上部,该上部支撑用于驱动冲击器的马达,所述冲击器位于流经所述喷嘴的下方。 除了最后一个出口通道通过过滤器排气之外,每个壳体部分还具有通向一系列冲击器腔室中的下冲击器腔室的出口通道。 冲击器室由在下一个下游壳体部分的颈部上密封的裙部限定。 冲击器板分别由单独的马达驱动,并且通过磁耦合器保持在电动机输出轴上的轮毂上,以便当壳体分离时可以移除板。
