Managing input/output interruptions in non-dedicated interruption hardware environments

A system of managing input/output (I/O) interruptions, said system comprising:

• means for aggregating in a list a plurality of notifications for a plurality of guest programs of a computing environment for which a plurality of I/O interruptions are to be presented;
• and
• means for providing the list to a hypervisor of the computing environment, the hypervisor to process at least one notification of the plurality of I/O notifications.

A system of managing input/output (I/O) interruptions, said system comprising:

• an aggregated list of a plurality of notifications for a plurality of guest programs of a computing environment for which a plurality of I/O interruptions are to be presented;
• and
• a hypervisor of the computing environment to process at least one notification of the plurality of notifications of the list.

An article of manufacture comprising:

• at least one computer usable medium having computer readable program code logic to manage input/output (I/O) interruptions, the computer readable program code logic comprising:
• logic to provide an I/O interruption to a dispatchable guest program in a computing environment, said computing environment to present I/O interruptions absent per-guest interruption hardware, wherein the logic to provide comprises logic to provide the I/O interruption absent intervention by a hypervisor of the computing environment, and wherein the guest program is dispatchable and not active, and the logic to provide comprises logic to present the I/O interruption to the guest program, in response to the guest program becoming active.
