This patch describes the procedure to be be followed
to perform Live Migration of a VM with Virtio and VF PMD's
using the bonding PMD.

It includes sample host and VM scripts used in the procedure,
and a sample switch configuration.

+
+Live Migration of VM with SR-IOV VF
+===================================
+
+Overview
+--------
+
+It is not possible to migrate a Virtual Machine which has an SR-IOV Virtual Function (VF).
+
+To get around this problem the bonding PMD is used.
+
+The following sections show an example of how to do this.
+
+Test Setup
+----------
+
+A bonded device is created in the VM.
+The virtio and VF PMD's are added as slaves to the bonded device.
+The VF is set as the primary slave of the bonded device.
+
+A bridge must be set up on the Host connecting the tap device, which is the
+backend of the Virtio device and the Physical Function (PF) device.
+
+To test the Live Migration two servers with identical operating systems installed are used.
+KVM and Qemu 2.3 is also required on the servers.
+
+In this example, the servers have Niantic and or Fortville NIC's installed.
+The NIC's on both servers are connected to a switch
+which is also connected to the traffic generator.
+
+The switch is configured to broadcast traffic on all the NIC ports.
+A :ref:`Sample switch configuration <lm_bond_virtio_sriov_switch_conf>`
+can be found in this section.
+
+The host is running the Kernel PF driver (ixgbe or i40e).
+
+The ip address of host_server_1 is 10.237.212.46
+
+The ip address of host_server_2 is 10.237.212.131
+
+Live Migration steps
+--------------------
+
+The sample scripts mentioned in the steps below can be found in the
+:ref:`Sample host scripts <lm_bond_virtio_sriov_host_scripts>` and
+:ref:`Sample VM scripts <lm_bond_virtio_sriov_vm_scripts>` sections.
+
+On host_server_1: Terminal 1
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: console
+
+   cd /root/dpdk/host_scripts
+   ./setup_vf_on_212_46.sh
+
+For Fortville NIC
+
+.. code-block:: console
+
+   ./vm_virtio_vf_i40e_212_46.sh
+
+For Niantic NIC
+
+.. code-block:: console
+

+.. code-block:: console
+
+   cd /root/dpdk/host_scripts
+   ./setup_bridge_on_212_46.sh
+   ./connect_to_qemu_mon_on_host.sh
+   (qemu)
+
+On host_server_1: Terminal 1
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**In VM on host_server_1:**
+
+.. code-block:: console
+
+   cd /root/dpdk/vm_scripts
+   ./setup_dpdk_in_vm.sh
+   ./run_testpmd_bonding_in_vm.sh
+
+   testpmd> show port info all
+
+The ``mac_addr`` command only works with kernel PF for Niantic
+
+.. code-block:: console
+
+   testpmd> mac_addr add port 1 vf 0 AA:BB:CC:DD:EE:FF
+
+The syntax of the ``testpmd`` command is:
+
+Create bonded device (mode) (socket).
+
+Mode 1 is active backup.
+
+Virtio is port 0 (P0).
+
+VF is port 1 (P1).
+
+Bonding is port 2 (P2).
+
+.. code-block:: console
+
+   testpmd> create bonded device 1 0
+   Created new bonded device eth_bond_testpmd_0 on (port 2).
+   testpmd> add bonding slave 0 2
+   testpmd> add bonding slave 1 2
+   testpmd> show bonding config 2
+
+The syntax of the ``testpmd`` command is:
+
+set bonding primary (slave id) (port id)
+
+Set primary to P1 before starting bonding port.
+
+.. code-block:: console
+
+   testpmd> set bonding primary 1 2
+   testpmd> show bonding config 2
+   testpmd> port start 2
+   Port 2: 02:09:C0:68:99:A5
+   Checking link statuses...
+   Port 0 Link Up - speed 10000 Mbps - full-duplex
+   Port 1 Link Up - speed 10000 Mbps - full-duplex
+   Port 2 Link Up - speed 10000 Mbps - full-duplex
+
+   testpmd> show bonding config 2
+
+Primary is now P1. There are 2 active slaves.
+
+Use P2 only for forwarding.
+
+.. code-block:: console
+
+   testpmd> set portlist 2
+   testpmd> show config fwd
+   testpmd> set fwd mac
+   testpmd> start
+   testpmd> show bonding config 2
+
+Primary is now P1. There are 2 active slaves.
+
+.. code-block:: console
+
+   testpmd> show port stats all
+
+VF traffic is seen at P1 and P2.
+
+.. code-block:: console
+
+   testpmd> clear port stats all
+   testpmd> set bonding primary 0 2
+   testpmd> remove bonding slave 1 2
+   testpmd> show bonding config 2
+
+Primary is now P0. There is 1 active slave.
+
+.. code-block:: console
+
+   testpmd> clear port stats all
+   testpmd> show port stats all
+
+No VF traffic is seen at P0 and P2, VF MAC address still present.
+
+.. code-block:: console
+
+   testpmd> port stop 1
+   testpmd> port close 1
+
+Port close should remove VF MAC address, it does not remove perm_addr.
+
+The ``mac_addr`` command only works with the kernel PF for Niantic.
+
+.. code-block:: console
+
+   testpmd> mac_addr remove 1 AA:BB:CC:DD:EE:FF
+   testpmd> port detach 1
+   Port '0000:00:04.0' is detached. Now total ports is 2
+   testpmd> show port stats all
+
+No VF traffic is seen at P0 and P2.

+
+Sample switch configuration
+---------------------------
+
+The Intel switch is used to connect the traffic generator to the
+NIC's on host_server_1 and host_server_2.
+
+In order to run the switch configuration two console windows are required.
+
+Log in as root in both windows.
+
+TestPointShared, run_switch.sh and load /root/switch_config must be executed
+in the sequence below.
+
+On Switch: Terminal 1
+~~~~~~~~~~~~~~~~~~~~~
+
+run TestPointShared
+
+.. code-block:: console
+
+   /usr/bin/TestPointShared
+
+On Switch: Terminal 2
+~~~~~~~~~~~~~~~~~~~~~
+
+execute run_switch.sh
+
+.. code-block:: console
+
+   /root/run_switch.sh
+
+On Switch: Terminal 1
+~~~~~~~~~~~~~~~~~~~~~
+
+load switch configuration
+
+.. code-block:: console
+
+   load /root/switch_config
+
+Sample switch configuration script
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``/root/switch_config`` script:
+
+.. code-block:: sh
+
+   # TestPoint History
+   show port 1,5,9,13,17,21,25
+   set port 1,5,9,13,17,21,25 up
+   show port 1,5,9,13,17,21,25
+   del acl 1
+   create acl 1
+   create acl-port-set
+   create acl-port-set
+   add port port-set 1 0
+   add port port-set 5,9,13,17,21,25 1
+   create acl-rule 1 1
+   add acl-rule condition 1 1 port-set 1
+   add acl-rule action 1 1 redirect 1
+   apply acl
+   create vlan 1000
+   add vlan port 1000 1,5,9,13,17,21,25
