+
+Poll Mode Driver that wraps vhost library
+=========================================
+
+This PMD is a thin wrapper of the DPDK vhost library.
+The user can handle virtqueues as one of normal DPDK port.
+
+Vhost Implementation in DPDK
+----------------------------
+
+Please refer to Chapter "Vhost Library" of *DPDK Programmer's Guide* to know detail of vhost.
+
+Features and Limitations of vhost PMD
+-------------------------------------
+
+Currently, the vhost PMD provides the basic functionality of packet reception, transmission and event handling.
+
+*   It has multiple queues support.
+
+*   It supports ``RTE_ETH_EVENT_INTR_LSC`` and ``RTE_ETH_EVENT_QUEUE_STATE_CHANGE`` events.
+
+*   It supports Port Hotplug functionality.
+
+*   Don't need to stop RX/TX, when the user wants to stop a guest or a virtio-net driver on guest.
+
+Vhost PMD arguments
+-------------------
+
+The user can specify below arguments in `--vdev` option.
+
+#.  ``iface``:
+
+    It is used to specify a path to connect to a QEMU virtio-net device.
+
+#.  ``queues``:
+
+    It is used to specify the number of queues virtio-net device has.
+    (Default: 1)
+
+Vhost PMD event handling
+------------------------
+
+This section describes how to handle vhost PMD events.
+
+The user can register an event callback handler with ``rte_eth_dev_callback_register()``.
+The registered callback handler will be invoked with one of below event types.
+
+#.  ``RTE_ETH_EVENT_INTR_LSC``:
+
+    It means link status of the port was changed.
+
+#.  ``RTE_ETH_EVENT_QUEUE_STATE_CHANGE``:
+
+    It means some of queue statuses were changed. Call ``rte_eth_vhost_get_queue_event()`` in the callback handler.
+    Because changing multiple statuses may occur only one event, call the function repeatedly as long as it doesn't return negative value.
+
+Vhost PMD with testpmd application
+----------------------------------
+
+This section demonstrates vhost PMD with testpmd DPDK sample application.
+
+#.  Launch the testpmd with vhost PMD:
+
+    .. code-block:: console
+
+        ./testpmd -c f -n 4 --vdev 'eth_vhost0,iface=/tmp/sock0,queues=1' -- -i
+
+    Other basic DPDK preparations like hugepage enabling here.
+    Please refer to the *DPDK Getting Started Guide* for detailed instructions.
+
+#.  Launch the QEMU:
+
+    .. code-block:: console
+
+       qemu-system-x86_64 <snip>
+                   -chardev socket,id=chr0,path=/tmp/sock0 \
+                   -netdev vhost-user,id=net0,chardev=chr0,vhostforce,queues=1 \
+                   -device virtio-net-pci,netdev=net0
+
+    This command attaches one virtio-net device to QEMU guest.
+    After initialization processes between QEMU and DPDK vhost library are done, status of the port will be linked up.
