Abstract
An invention is disclosed for effectuating direct memory access (DMA) transfers by a guest operating system of a child partition. A guest operating system is presented with virtualized resources rather than physical resources—e.g. a virtualized processor, virtualized memory, and a virtualized DMA controller. When the guest OS attempts to initiate a DMA transfer using the virtualized DMA controller, the child partition detects this, and directs the physical DMA controller to conduct the DMA transfer.
