OVS Installation on CentOS 6 or 7

  1. yum update -y
  2. yum install gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel autoconf automake rpm-build redhat-rpm-config libtool checkpolicy selinux-policy-devel python-six
  3. We can find OpenvSwitch in RDO repo (RDO is a community of people using and deploying OpenStack on CentOS, Fedora and RHEL):
    1. wget https://rdoproject.org/repos/rdo-release.rpm 
    2. rpm -i rdo-release.rpm
  4. yum install openvswitch
  5. Enable OVS daemon on startup and start it:
    1. On CentOS 6
      1. chkconfig openvswitch on
      2. service openvswitch start
    2. On CentOS 7:
      1. systemctl -l start openvswitch.service
      2. systemctl -l enable openvswitch.service
  6.  In order to avoid possible conflicts in networking:
    1. yum remove NetworkManager
  7. To verify your OVS installation:
    1. ovs-vsctl -V
      ovs-vsctl (Open vSwitch) 2.5.0
      Compiled Mar 18 2016 15:00:11
      DB Schema 7.12.1
    2.  ovs-vsctl show
      1c490f2d-68c0-4dd0-a0de-cdcaa944711a

    Step 4 above on CentOS 6.10 x86_64 produced the following message:
    Error: Package: 1:openvswitch-2.9.0-3.el7.x86_64 (openstack-queens)
    Requires: systemd-units

    It's my understanding that systemd-units is a CentOS 7 module.
    How do I correct this issue on CentOS 6 x86_64?

      My pity, for now only RDO releases with CentOS7 suport are maintained, and the last release (as I know) with the CentOS6 support was Mitaka, so try:
      yum install centos-release-openstack-mitaka
      instead of:
      wget https://rdoproject.org/repos/rdo-release.rpm
      rpm -i rdo-release.rpm
