Therefore, a NIC is logically distributed among multiple virtual machines (as shown in :numref:`figure_single_port_nic`),
while still having global data in common to share with the Physical Function and other Virtual Functions.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In a virtualized environment, the programmer can enable a maximum of *128 Virtual Functions (VF)*
globally per Intel® X710/XL710 Gigabit Ethernet Controller NIC device.
-The number of queue pairs of each VF can be configured by ``CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VF`` in ``config`` file.
The Physical Function in host could be either configured by the Linux* i40e driver
(in the case of the Linux Kernel-based Virtual Machine [KVM]) or by DPDK PMD PF driver.
When using both DPDK PMD PF/VF drivers, the whole NIC will be taken over by DPDK based application.

Setting Up a KVM Virtual Machine Monitor
----------------------------------------
#. Create a Virtual Machine and install Fedora 14 on the Virtual Machine.
This is referred to as the Guest Operating System (Guest OS).
-#. Download and install the latest ixgbe driver from:
-
- `http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=14687 <http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=14687>`_
+#. Download and install the latest ixgbe driver from
+ `intel.com <https://downloadcenter.intel.com/download/14687>`_.
#. In the Host OS
.. code-block:: console
- make install T=x86_64-native-linuxapp-gcc
- ./x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
+ ./<build_dir>/app/dpdk-testpmd -l 0-3 -n 4 -- -i
#. Finally, access the Guest OS using vncviewer with the localhost:5900 port and check the lspci command output in the Guest OS.
The virtual functions will be listed as available for use.
-#. Configure and install the DPDK with an x86_64-native-linuxapp-gcc configuration on the Guest OS as normal,
- that is, there is no change to the normal installation procedure.
-
- .. code-block:: console

+
+Windows Support
+---------------
+
+* IAVF PMD currently is supported only inside Windows guest created on Linux host.
+
+* Physical PCI resources are exposed as virtual functions
+ into Windows VM using SR-IOV pass-through feature.
+
+* Create a Windows guest on Linux host using KVM hypervisor.
+ Refer to the steps mentioned in the above section: :ref:`intel_vf_kvm`.
+
+* In the Host machine, download and install the kernel Ethernet driver
+ for `i40e <https://downloadcenter.intel.com/download/24411>`_
+ or `ice <https://downloadcenter.intel.com/download/29746>`_.
+
+* For Windows guest, install NetUIO driver
+ in place of existing built-in (inbox) Virtual Function driver.
+
+* To load NetUIO driver, follow the steps mentioned in `dpdk-kmods repository
+ <https://git.dpdk.org/dpdk-kmods/tree/windows/netuio/README.rst>`_.
+
+
+Inline IPsec Support
+--------------------
+
+* IAVF PMD supports inline crypto processing depending on the underlying
+ hardware crypto capabilities. IPsec Security Gateway Sample Application
+ supports inline IPsec processing for IAVF PMD. For more details see the
+ IPsec Security Gateway Sample Application and Security library
+ documentation.
