Abstract
A system includes a physical host, a host operating system, and a virtual machine having a virtual network-interface controller. The virtual network-interface controller comprises an uplink, a virtual function, and a physical function having a physical channel and a virtual channel. The hypervisor is configured to receive data that originates at the virtual function, which is forwarded to the physical function on the physical channel of the physical function. The data is further forwarded from the physical function to the uplink. Additionally, the hypervisor is configured to send data that does not originate at the virtual function. The hypervisor sends the data on the virtual channel of the physical function and the physical function forwards the data to the virtual function.
