Dynamic network adapter queue pair allocation

摘要

A system receives a notification at an operating system image of a change in allocation of queue pair resources to the operating system image. The system queries a physical network adapter through a hypervisor to obtain a new queue pair resource count that will exist in the virtualized system after the change in allocation. The system performs a hashing operation in the operating system image using the new queue pair resource count to distribute transmit traffic among the queue pair resources that will exist in the virtualized system after the change in allocation.
