Abstract
A method for controlling a network interface controller (NIC). The method includes receiving, by a host operating system (OS) executing on a computer system, an instruction to map the NIC virtual function (VF) to a first virtual machine executing on the computer system. The method further includes allocating, according to the NIC VF, first NIC resources on a physical NIC operatively connected to the computer system, mapping the NIC VF to the first virtual machine, creating, in the host OS, a shadow virtual NIC for the first NIC resources allocated to the NIC VF, assigning the shadow virtual NIC to the first virtual machine, receiving, by the physical NIC, a first packet targeting the first virtual machine, and sending the first packet directly to the first virtual machine.
