Zusammenfassung:	Provided are a computer product, system, and method for dynamic assignment of device queues to virtual functions to provide to virtual machines. Queues are assigned to a virtual function to access the physical functions of the device. The virtual function is provided to a virtual machine to use to access the physical functions of the device. A determination is made of a utilization of the queues assigned to the virtual function accessed by the virtual machine. A number of the queues assigned to the virtual functions for requests submitted by the virtual machine is changed in response to the determined utilization.
