Abstract
An input/output (I/O) device is coupled to a processor via a first peripheral bus and a second peripheral bus. The I/O device is configured to expose a first physical function (PF) and a second PF to a virtual machine (VM) executing on the processor. A first virtual function (VF) associated with the first PF is assigned to the first peripheral bus, and a second VF associated with the second PF is assigned to the second peripheral bus. The first VF and the second VF are exposed as a single VF to the VM. The VM can perform transactions with the I/O device via the single VF using the first peripheral bus and the second peripheral bus.
