SYSTEMS AND METHODS FOR SR-IOV PASS-THRU VIA AN INTERMEDIARY DEVICE

摘要

This disclosure describes a system for Single Root I/O Virtualization (SR-IOV) pass-thru for network packet processing via a virtualized environment of a device. The system includes a device comprising a virtualized environment and a plurality of virtual machines having a virtual network interface for receiving and transmitting network packets. A driver for the physical network interface of the device creates a plurality of virtual devices corresponding to the physical network interface, which appear as a Peripheral Component Interconnect (PCI) device to the virtualized environment. A virtual device of the plurality of virtual devices is assigned via the virtualized environment to each virtual machine of the plurality of virtual machines. The virtual machine uses the virtual device assigned to the virtual machine, to receive and transmit network packets via the physical network interface of the device.

主权项

1. A method for Single Root I/O Virtualization (SR-IOV) pass-thru for network packet processing via a virtualized environment of a device, the method comprising:
(a) establishing, on a device, a virtualized environment comprising a plurality of virtual machines, each virtual machine of the plurality of virtual machines having a virtual network interface for receiving and transmitting network packets; (b) creating, via a driver for a physical network interface of the device, a plurality of virtual devices corresponding to the physical network interface, the physical network interface comprising a Single Root I/O Virtualization (SR-IOV) enabled device, each virtual device of the plurality of virtual devices appearing as a Peripheral Component Interconnect (PCI) device to the virtualized environment; (c) assigning a virtual device of the plurality of virtual devices to each virtual machine of the plurality of virtual machines, each virtual machine comprising a driver to communicate to the virtual device; and (d) receiving and transmitting, by the virtual machine using the virtual device assigned to the virtual machine, network packets via the physical network interface of the device.
