Abstract
In one embodiment, a computer-implemented method includes assigning a time budget to each of a plurality of virtual functions in a single-root input/output (SRIOV) environment, where a first time budget of a first virtual function indicates a quantity of cycles on an engine of the SRIOV environment allowed to the first virtual function within a time slice. A plurality of requests issued by the plurality of virtual functions are selected by a computer processor, where the selecting excludes requests issued by virtual functions that have used their associated time budgets of cycles in a current time slice. The selected plurality of requests are delivered to the engine for processing. The time budgets of the virtual functions are reset and a new time slice begins, at the end of the current time slice.
