Interpreting I/O operation requests from pageable guests without host intervention

A method of facilitating processing of input/output (I/O) operations in a pageable mode virtual environment, said method comprising:

• processing by a processor of the pageable mode virtual environment an I/O operation of a guest program operating in a virtual machine of the pageable mode virtual environment, wherein the processing is absent intervention by a host of the pageable mode virtual environment.

A system of facilitating data transfer in a pageable mode virtual environment, said system comprising:

• means for 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
• means for 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.

A system of facilitating data transfer in a pageable mode virtual environment, said system comprising:

• a processor of the pageable mode virtual environment adapted to obtain 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
• the processor being further adapted to perform processing associated with the buffer to enable data transfer, the performing being absent intervention of a host of the pageable mode virtual environment.

The article of manufacture of 60, further comprising interrogate logic to interrogate by the guest program state of the buffer.
