BackendDriver

From Xen


To allow unprivileged DomUs to share hardware, Dom0 must give them an interface by which to make requests for access to the hardware. This is accomplished by using a BackendDriver. The BackendDriver runs in Dom0 or a DriverDomain and communicates with FrontendDrivers via XenBus, XenStore, and shared memory pages. It queues requests from DomUs and relays them to the real hardware driver.
