    Build OVN

    Update & install dependencies

    1. apt-get update
    2. apt-get -y install build-essential fakeroot

    Install Build-Depends from debian/control file

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

    Check the working directory & build

    1. curl -o openvswitch-2.7.0.tar.gz http://openvswitch.org/releases/openvswitch-2.7.0.tar.gz
    2. tar zxvf openvswitch-2.7.0.tar.gz
    3. cd openvswitch-2.7.0
    5. # if everything is ok then this should return no output
    6. dpkg-checkbuilddeps
    8. `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

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

    Build kernel modules using module-assistant

    1. m-a prepare
    2. m-a build openvswitch-datapath

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

    1. cp /usr/src/openvswitch-datapath-module-*.deb ./
    2. apt-get -y install python-six python2.7
    3. dpkg -i openvswitch-datapath-module-*.deb
    4. dpkg -i openvswitch-common_2.7.0-1_amd64.deb openvswitch-switch_2.7.0-1_amd64.deb
    5. dpkg -i ovn-central_2.7.0-1_amd64.deb ovn-common_2.7.0-1_amd64.deb ovn-controller-vtep_2.7.0-1_amd64.deb ovn-docker_2.7.0-1_amd64.deb ovn-host_2.7.0-1_amd64.deb python-openvswitch_2.7.0-1_all.deb
