Abstract
An invention is disclosed for offloading operations, such data transfers, of a guest partition to a host partition. A guest operating system is presented with virtualized resources rather than physical resources—e.g. a guest virtualized processor, guest virtualized memory space, and a guest virtualized direct memory access (DMA) controller. The guest partition can detect the guest operation system attempt to initiate a data transfer, and can instruct the host partition to perform the data transfer. The guest partition need not perform the data transfer using the guest virtual resources. The host partition can perform the data transfer to a remote computing as instructed by the guest partition without copying the data to the host virtualized memory space. The host partition can provide a message to the guest partition indicative of a status of the data transfer.
