Build OVN

Update & install dependencies

apt-get update
apt-get -y install build-essential fakeroot

Install Build-Depends from debian/control file

apt-get -y install graphviz autoconf automake bzip2 debhelper dh-autoreconf libssl-dev libtool openssl
apt-get -y install procps python-all python-twisted-conch python-zopeinterface python-six

Check the working directory & build

curl -o openvswitch-2.7.0.tar.gz
tar zxvf openvswitch-2.7.0.tar.gz
cd openvswitch-2.7.0

# if everything is ok then this should return no output

`DEB_BUILD_OPTIONS='parallel=8 nocheck' fakeroot debian/rules binary`

The .deb files for ovs will be built and placed in the parent directory (ie. in …/). The next step is to build the kernel modules.

Install datapath sources

cd ..
apt-get -y install module-assistant
dpkg -i openvswitch-datapath-source_2.7.0-1_all.deb

Build kernel modules using module-assistant

m-a prepare
m-a build openvswitch-datapath

Copy the resulting deb package. Note that your version may differ slightly depending on your specific kernel version.

cp /usr/src/openvswitch-datapath-module-*.deb ./
apt-get -y install python-six python2.7
dpkg -i openvswitch-datapath-module-*.deb
