This wiki describes all the steps necessary to setup a testbed of Openstack Folsom nodes (All-in-one node and Compute nodes), which rely on a LISP-enabled OpenVSwitch (OVS) bridge.

Testbed Setup


The Openstack nodes are considered hereafter to be Ubuntu 12.04.1 LTS (Precise Pangolin) machines (running the 3.2.0-29 kernel version). The following dependencies need to be met.

sudo apt-get update
sudo apt-get upgrade (NOT dist-upgrade)

sudo apt-get install openssh-server vim git openssh-server bridge-utils build-essential git-core libssl-dev libconfuse-dev pkg-config autoconf libtool pkg-config gengetopt \
 clang mosh cscope vim-gtk htop subversion tmux iotop dpatch automake1.9 python-support uml-utilities farpd

sudo apt-get install linux-headers-3.2.0-29-generic

# For KVM
sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils virt-manager virtinst

In case you wish to also use Wireshark (with LISP dissector included):

$ sudo apt-get build-dep wireshark
$ sudo apt-get install autoconf bison flex libtool libgtk2.0-dev libpcap-dev libc-ares-dev libsmi2-dev libgnutls-dev libgcrypt11-dev libkrb5-dev libcap2-bin libgeoip-dev libortp-dev libportaudio-dev

$ mkdir ~/Downloads; cd ~/Downloads; wget
$ tar -xvf wireshark-1.8.3.tar.bz2 -C /tmp
$ cd /tmp/wireshark-1.8.3/
$ ./
$ ./configure --enable-setcap-install
$ make
$ sudo make install
$ sudo ldconfig
$ wireshark &

Although this is simply a recommendation, the testbed has been successfully run with the following memory settings:

  • 1.8GB for the All-In-One Node
  • 1.2GB for the Compute Node

[] OVS-LISP bridge
() Network interface

If instead of physical machines you plan on setting this testbed up with VMware Fusion, make sure the network is configured as Bridged (Ethernet).

Map Server (MS)

Just to get an idea of how the EID addresses are supposed to be associated with their corresponding RLOCs, you can have a look at the following MS configuration, which makes static assignments.

Under regular LISP operation you will not have to impose the following configuration. Rather, it is formed automatically and dynamically.

<?xml version="1.0" encoding="ISO-8859-1"?>


  <eid prefix="" act="2" ttl="5" />
  <eid prefix="" act="2" ttl="5" />
  <eid prefix="" act="2" ttl="5" />
  <eid prefix="" act="2" ttl="5" />

  <eid prefix="" ttl="1440" A="true">

  <eid prefix="" ttl="1440" A="true">


Installing the LISP-enabled OVS bridge

On both machines do the following. First download the corresponding code:

cd /home/user/
git clone https://

First install lispmob:

cd /home/user/lispmob-ovs/
sudo make install
sudo depmod -a

Afterward install the modified LISP-enabled OpenVswitch:

cd /home/user/ovs-lisp/
./configure --with-linux=/lib/modules/`uname -r`/build
cp /home/user/lispmob-ovs/lisp_mod/Module.symvers /home/user/ovs-lisp/datapath/linux/
sudo vi /home/user/ovs-lisp/datapath/linux/

...and remove 'Module.symvers' from the 'clean' target (on line 33)

sudo reboot

Then, you will need to REMAKE and REINSTALL lisp

cd /home/lakafosi/lispmob-ovs
sudo make install
sudo depmod -a

cd /home/lakafosi/ovs-lisp/
sudo make install
sudo depmod -a

sudo dmesg -c

In order to bring up the OVS bridge:

sudo /home/user/ovs-scripts/ovs-start

which includes:


rmmod -s openvswitch
modprobe lisp
insmod ${BUILD_DIR}/datapath/linux/openvswitch.ko
mkdir -p ${OVS_PATH}/etc/openvswitch
rm ${OVS_PATH}/etc/openvswitch/conf.db
ovsdb-tool create /usr/local/etc/openvswitch/conf.db /home/lakafosi/ovs-lisp/vswitchd/vswitch.ovsschema
${OVS_PATH}/sbin/ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
                     --remote=db:Open_vSwitch,manager_options \
                     --private-key=db:SSL,private_key \
                     --certificate=db:SSL,certificate \
                     --bootstrap-ca-cert=db:SSL,ca_cert \
                     --pidfile --detach
${OVS_PATH}/bin/ovs-vsctl --no-wait init
${OVS_PATH}/sbin/ovs-vswitchd --pidfile --detach
ps -ea | grep ovs; ps -ea | grep lisp; lsmod | grep lisp; lsmod | grep ovs

You can verify everything is setup correctly by issuing:

ps -ea | grep ovs; ps -ea | grep lisp; lsmod | grep lisp; lsmod | grep ovs

which should yield an output similar to the following:

 1404 ?        00:00:00 ovs_workq 1406 ?        00:00:00 ovsdb-server
 1409 ?        00:00:00 ovs-vswitchd
 1410 ?        00:00:00 ovs-vswitchd
lisp                   41286  1 openvswitch


First create the stack user in order to install and run Openstack without any passwords requested.

su -
useradd -U -G sudo -s /bin/bash -m stack; echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
su stack

This Openstack installation is based on Devstack.

It is important you stick with the stable Folsom version:

git clone -b stable/folsom


git clone -b stable/folsom git://

Additionally, you will have to download one more script for setting up the OVS-bridge and attaching the vnetX ports of the instantiated VMs, the lispd.conf control plane configuration file of LISP and a few cloud qcow2 (Ubuntu and Fedora) images (to use in addition to the preloaded tiny CirrOS cloud guest).

mkdir /home/stack/Downloads
mv /* /home/stack/devstack/Downloads/* /home/stack/Downloads
