ABSTRACT:
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.
