Abstract
An embodiment of the present invention is a technique to process an input/output (I/O) transaction. An emulated device driver in a guest partition interacts with a virtual machine (VM) manager in processing an input/output (I/O) transaction on behalf of an application via an operating system (OS). The I/O transaction is between the application and a device. A device emulator in a service partition communicatively coupled to the emulated device driver interacts with the VM manager in processing the I/O transaction on behalf of a device specific driver via the OS. The device specific driver interfaces to the device.
