This document provides configuration notes for using the Intel 82599 10G NIC's SRIOV functionality to assign virtual functions to a virtual machine on an Ubuntu Linux host. It outlines downloading the driver, declaring the number of virtual functions, verifying the modules and virtual functions are present on the host, creating an XML file to attach a virtual function to a VM, and verifying the VM can see the attached NIC.
