Abstract

Techniques for achieving Input/Output I/O coalition across multiple computing systems and/or environments (e.g., computing devices) are disclosed. I/O coalition can be achieved by allowing one or more internal I/O devices of a first computing device to be effectively shared with a second computing device while one or more I/O devices of the second computing device is effectively shared with the first computing device. An Input-Output Coalition Management (IOCM) system can be provided for each the computing devices to facilitate I/O coalition between them. An IOCM system can, for example, be provided as Virtual Input-Output Computing Environment (VIOCE). By way of example, one or more Virtual Machines (VMs) can be provided to effectively support one or more Virtual Device Drivers (VDDs). An IOCM system can also be provided as and/or by an Operating System (OS). Furthermore, an IOCM system of a first computing device can be operable to switch between: (i) use of a first I/O device of the first computing device, (ii) use of a second I/O device of a second computing device, and (iii) use of a third I/O device of a third computing device.
