摘要： A method, apparatus and system are described for seamlessly sharing I/O devices amongst multiple virtual machines (“VMs”) on a host computer. Specifically, according to one embodiment of the invention, the virtual machine manager (“VMM”) on the host cycles access to the I/O devices amongst the VMs according to a round robin or other such allocation scheme. In order to provide direct access to the devices, the VMM may save the device state pertaining to the currently active VM, store the state in a memory region allocated to the currently active VM, retrieve a device state for a new VM from its memory region and restore the device using the retrieved device state, thus providing the illusion that each VM has direct, full-speed, exclusive access to the I/O device.

摘要： A method, apparatus and system enable a virtual machine manager (“VMM”) to dynamically reassign physical devices from one virtual machine (“VM”) to another. The VMM may generate a message to the VM that currently owns the physical device and inform the device that the physical device is shutting down. The current VM may thereafter idle the physical device, unload the device driver and eject the device. The VMM may then inform another VM that the physical device is available, and the second VM may load the driver for the device.

摘要： In a data processing system that executes a program of instructions, a method for generating a detail-in-context presentation of a three-dimensional information representation comprising the steps of selecting a object-of-interest in the information representation; selecting a viewpoint; selecting a path from the viewpoint to the object-of-interest; and, displacing objects in the information representation away from the path to locations within the information representation where the objects remain visible when viewed from the viewpoint yet do not occlude the object-of-interest when viewed from the viewpoint to thereby generate the detail in context view.

摘要： A method, apparatus and system are described for seamlessly and concurrently sharing a graphics device amongst multiple virtual machines (“VMs”) on a host computer. Specifically, according to one embodiment of the invention, a graphics device may be shared by multiple VMs such that only the output of one VM (i.e., the “focus VM”) is displayed on a display device coupled to the host computer. The focus VM may be identified according to a variety of ways. The focus VM may render its output into a frame-buffer and/or an overlay buffer, and the page table entries (“PTEs) that point to the frame-buffer may then be copied to a display buffer in an unused memory location associated with the focus VM. The PTEs may additionally be copied to display buffers in unused memory locations associated with the non-focus VMs on the host. The display buffer may then output its display (via the pointers to the frame buffers) to the display device. This output remains that of the focus VM until a different VM is selected as the new focus VM. The process may then repeat itself.
摘要翻译：描述了用于在主计算机上的多个虚拟机（“VM”）之间无缝并同时共享图形设备的方法，装置和系统。具体地，根据本发明的一个实施例，图形设备可以由多个VM共享，使得仅在耦合到主计算机的显示设备上显示一个VM（即，“焦点VM”）的输出。焦点VM可以根据各种方式来识别。焦点VM可以将其输出呈现到帧缓冲器和/或覆盖缓冲器中，并且指向帧缓冲器的页表条目（“PTE”）可以被复制到与...相关联的未使用的存储器位置中的显示缓冲器焦点虚拟机，PTE可以另外被复制到在与主机上的非聚焦VM相关联的未使用的存储器位置中显示缓冲器，然后显示缓冲器可以将其显示（经由指针到帧缓冲器）输出到显示设备。该输出仍然是焦点VM的输出，直到选择不同的VM作为新的聚焦VM，然后该过程可以重复。
