1. A computer-implemented method of facilitating data transfer in a pageable mode virtual environment, said computer-implemented method comprising: obtaining, by a processor of the pageable mode virtual environment, an indication of a buffer to be used in data transfer, the buffer being associated with a guest program operating in a pageable mode virtual machine of the pageable mode virtual environment; and performing, by the processor, processing associated with the buffer to enable data transfer, the performing being absent intervention of a host of the pageable mode virtual environment, and wherein the performing includes managing state of the buffer.
