| 2. An article of manufacture comprising:
at least one computer usable storage medium having computer readable program code logic stored thereon to manage input/output
(I/O) interruptions, the computer readable program code logic comprising:
logic to obtain an I/O interruption for a guest program of a virtualized real memory environment;
logic to determine a dispatch state of the guest program;
logic to provide the I/O interruption to the guest program absent intervention by a hypervisor of the virtualized real memory
environment, in response to the dispatch state being of one state; and
logic to provide the I/O interruption to the guest program with hypervisor intervention, in response to the dispatch state
being of another state.
