-Setup
-=====
-
-This section describes how to setup ``spp_vf`` and ``spp_mirror``.
-
-
-Environment
------------
-
-Here is a recommended versions of each of software.
-
-* Ubuntu 16.04
-* qemu-kvm 2.7 or later
-
-.. note::
-
-    If you do not use ``--vhost-client`` described in
-    :ref:`How to Use<spp_vf_gsg_howto_use_spp_mirror>`
-    , you can use previous versions of qemu-kvm.
-
-
-Edit Config
------------
-
-Uncomment user and group in ``/etc/libvirt/qemu.conf``.
-
-.. code-block:: console
-
-    # /etc/libvirt/qemu.conf
-
-    user = "root"
-    group = "root"
-
-To use hugepages with libvirt, change ``KVM_HUGEPAGES`` from 0 to 1
-in ``/etc/default/qemu-kvm``.
-
-.. code-block:: console
-
-    # /etc/default/qemu-kvm
-
-    KVM_HUGEPAGES=1
-
-Change grub configuration for hugepages and isolcpus features. It is defined
-as ``GRUB_CMDLINE_LINUX_DEFAULT`` and takes parameters.
-
-* isolcpus: Core IDs separated with commna, such as ``2,3,4,8``
-* hugepagesz: The size of hugepage, such as ``2M`` or ``1G``
-* hugepages: The number of hugepages, such as ``8``
-* default_hugepagesz: Default hugepage size, required only for ``1G``
-
-In this setup guide, configure ``hugepagez`` and its default is ``1G`` and
-the number of hugepages is ``36``.
-Core IDs of for ``isolcpus`` depends on your environment and usecase,
-but should be configured to have enough number of cores.
-
-.. code-block:: c
-
-    # /etc/default/grub
-
-    GRUB_CMDLINE_LINUX_DEFAULT="isolcpus=2,...,46 hugepagesz=1G hugepages=..."
-
-For hugepages, isolcpus, refer to the dpdk documentation below.
-
-* `Use of Hugepages in the Linux Environment
-  <http://dpdk.org/doc/guides/linux_gsg/sys_reqs.html#running-dpdk-applications>`_
-* `Using Linux Core Isolation to Reduce Context Switches
-  <http://dpdk.org/doc/guides/linux_gsg/enable_func.html#using-linux-core-isolation-to-reduce-context-switches>`_
-* `Linux boot command line
-  <http://dpdk.org/doc/guides/linux_gsg/nic_perf_intel_platform.html#linux-boot-command-line>`_
-
-You need to run ``update-grub`` and reboot to activate grub config.
-
-.. code-block:: console
-
-    $ sudo update-grub
-    $ sudo reboot
-
-
-You can check hugepage settings as following.
-
-.. code-block:: console
-
-    $ cat /proc/meminfo | grep -i huge
-    AnonHugePages:      2048 kB
-    HugePages_Total:      36		#	/etc/default/grub
-    HugePages_Free:       36
-    HugePages_Rsvd:        0
-    HugePages_Surp:        0
-    Hugepagesize:    1048576 kB		#	/etc/default/grub
-
-    $ mount | grep -i huge
-    cgroup on /sys/fs/cgroup/hugetlb type cgroup (rw,...,nsroot=/)
-    hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime)
-    hugetlbfs-kvm on /run/hugepages/kvm type hugetlbfs (rw,...,gid=117)
-    hugetlb on /run/lxcfs/controllers/hugetlb type cgroup (rw,...,nsroot=/)
-
-Finally, you umount default hugepage.
-
-.. code-block:: console
-
-    $ sudo umount /dev/hugepages
-
-
-Install DPDK
-------------
-
-Install DPDK in any directory. This is a simple instruction and please
-refer
-`Getting Started Guide for Linux
-<http://dpdk.org/doc/guides/linux_gsg/index.html>`_
-for details.
-
-.. code-block:: console
-
-    $ cd /path/to/any_dir
-    $ git clone http://dpdk.org/git/dpdk
-    $ cd dpdk
-    $ git checkout [TAG_NAME(e.g. v17.05)]
-    $ export RTE_SDK=`pwd`
-    $ export RTE_TARGET=x86_64-native-linuxapp-gcc
-    $ make T=x86_64-native-linuxapp-gcc install
-
-
-Install SPP
------------
-
-Clone SPP in any directory and compile it.
-
-.. code-block:: console
-
-    $ cd /path/to/any_dir
-    $ git clone http://dpdk.org/git/apps/spp
-    $ cd spp
-    $ make
-
-Setup for DPDK
---------------
-
-Load igb_uio module.
-
-.. code-block:: console
-
-    $ sudo modprobe uio
-    $ sudo insmod $RTE_SDK/x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
-    $ lsmod | grep uio
-    igb_uio                16384  0  # igb_uio is loaded
-    uio                    20480  1 igb_uio
-
-Then, bind your devices with PCI number by using ``dpdk-devbind.py``.
-PCI number is inspected
-
-.. code-block:: console
-
-    # check your device for PCI_Number
-    $ $RTE_SDK/usertools/dpdk-devbind.py --status
-
-    $ sudo $RTE_SDK/usertools/dpdk-devbind.py --bind=igb_uio PCI_NUM
-
-
-virsh setup
------------
-
-First of all, please check version of qemu-kvm.
-
-.. code-block:: console
-
-    $ qemu-system-x86_64 --version
-
-If your system does not have qemu-kvm or the version of qemu is less than 2.7,
-then please install qemu following
-the instruction of https://wiki.qemu.org/index.php/Hosts/Linux
-to install qemu 2.7.
-You may need to install libvirt-bin,
-virtinst, bridge-utils packages via ``apt-get`` install to run
-``virt-install``.
-
-
-``virsh`` is a command line interface that can be used to create, destroy,
-stop start and edit VMs and configure. After create an image file,
-you can setup it with ``virt-install``.
-``--location`` is a URL of installer and it should be
-``http://archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/``
-for amd64.
-
-.. code-block:: console
-
-   virt-install \
-   --name [VM_NAME] \
-   --ram 4096 \
-   --disk path=/var/lib/libvirt/images/[VM_NAME].img,size=30 \
-   --vcpus 4 \
-   --os-type linux \
-   --os-variant ubuntu16.04 \
-   --network network=default \
-   --graphics none \
-   --console pty,target_type=serial \
-   --location '[LOCATION]' \
-   --extra-args 'console=ttyS0,115200n8 serial'
-
-You may need type the following commands through ssh to activate console.
-
-.. code-block:: console
-
-    $sudo systemctl enable serial-getty@ttyS0.service
-    $sudo systemctl start serial-getty@ttyS0.service
-
-
-Edit VM configuration with virsh.
-
-.. code-block:: console
-
-    $ virsh edit [VM_NAME]
-
-You need to add ``xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'``
-into the domain tag because of adding ``<qemu:commandline>`` tag.
-In addition, you need to add the tag enclosed by ``<memoryBacking>`` and
-``</memoryBacking>``, ``<qemu:commandline>`` and ``</qemu:commandline>``
-because SPP uses vhost-user as interface with VM.
-Note that number used in those tags should be the same value
-(e.g. chr0,sock0,vhost-net0) and these values should correspond
-to "add vhost N" (in this example 0).
-MAC address used in
-``<qemu:arg value='virtio-net-pci,netdev=vhost-net0,mac=52:54:00:12:34:56'/>``
-can be specified when registering MAC address to classifier
-using Secondary command.
-
-        The following is an example of modified xml file:
-
-.. code-block:: xml

-Setup spp_mirror
-----------------
-
-Setup of ``spp_mirror`` is almost the same as :ref:`SPP VF<spp_vf_gsg_build>`.
-Configuration of use of ``shallowcopy`` or ``deepcopy`` is different from
-``spp_vf``.
-It is defined in ``src/mirror/Makefile`` and which of copying is used is
-configured by editing ``CFLAG`` option. It is defined to use ``shallowcopy``
-by default.
-
-If you use ``deepcopy``, comment out the line of ``-Dspp_mirror_SHALLOWCOPY``
-to be disabled.
-
-.. code-block:: c
-
-   #CFLAGS += -Dspp_mirror_SHALLOWCOPY
-
-Then, run make command to compile ``spp_mirror``.
-
-.. code-block:: console
-
-   $ make
-
-
-Trouble Shooting Guide
-----------------------
-
-You might encounter a permission error for ``tmp/sockN`` because
-of appamor.
-In this case, you should try it.
-
-.. code-block:: console
-
-    #Edit /etc/libvirt/qemu.conf and set security_driver to none:
-    $sudo vi /etc/libvirt/qemu.conf
-    ...
-    security_driver = "none"
-    ...
-    #Restart libvirtd:
-    $sudo systemctl restart libvirtd.service
-
-Or, you remove appamor.
-
-.. code-block:: console
-
-    $ sudo apt-get remove apparmor
-
-If you use CentOS, not Ubuntu, confirm that SELinux doesn't prevent
-for permission.
-SELinux should be disabled in this case.
-
-.. code-block:: console
-
-    # /etc/selinux/config
-    SELINUX=disabled
-
-Check your SELinux configuration.
-
-.. code-block:: console
-
-    $ getenforce
-    Disabled

+for amd64.
+

+.. code-block:: console
+
+    $ virsh edit [VM_NAME]
+
+You need to add ``xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'``
+into the domain tag because of adding ``<qemu:commandline>`` tag.
+In addition, you need to add the tag enclosed by ``<memoryBacking>`` and
+``</memoryBacking>``, ``<qemu:commandline>`` and ``</qemu:commandline>``
+because SPP uses vhost-user as interface with VM.
+Note that number used in those tags should be the same value
+(e.g. chr0,sock0,vhost-net0) and these values should correspond
+to "add vhost N" (in this example 0).
+MAC address used in
+``<qemu:arg value='virtio-net-pci,netdev=vhost-net0,mac=52:54:00:12:34:56'/>``
+can be specified when registering MAC address to classifier
+using Secondary command.

+Setup spp_mirror
+----------------
+
+Setup of ``spp_mirror`` is almost the same as :ref:`SPP VF<spp_vf_gsg_setup>`.
+Configuration of use of ``shallowcopy`` or ``deepcopy`` is different from
+``spp_vf``.
+It is defined in ``src/mirror/Makefile`` and which of copying is used is
+configured by editing ``CFLAG`` option. It is defined to use ``shallowcopy``
+by default.
+
+If you use ``deepcopy``, comment out the line of ``-Dspp_mirror_SHALLOWCOPY``
+to be disabled.
+
+.. code-block:: c
+
+   #CFLAGS += -Dspp_mirror_SHALLOWCOPY
+
+Then, run make command to compile ``spp_mirror``.
+
+.. code-block:: console
+
+   $ make
+
+
+Trouble Shooting Guide
+----------------------
+
+You might encounter a permission error for ``tmp/sockN`` because
+of appamor.
+In this case, you should try it.
+
+.. code-block:: console
+
+    #Edit /etc/libvirt/qemu.conf and set security_driver to none:
+    $sudo vi /etc/libvirt/qemu.conf
+    ...
+    security_driver = "none"
+    ...
+    #Restart libvirtd:
+    $sudo systemctl restart libvirtd.service
+
+Or, you remove appamor.
+
+.. code-block:: console
+
+    $ sudo apt-get remove apparmor
+
+If you use CentOS, not Ubuntu, confirm that SELinux doesn't prevent
+for permission.
+SELinux should be disabled in this case.
+
+.. code-block:: console
+
+    # /etc/selinux/config
+    SELINUX=disabled
+
+Check your SELinux configuration.
+
+.. code-block:: console
+
+    $ getenforce
+    Disabled
