= Configure and Initialize Services: Configure your OpenFlow switch = Although OVS is installed and initialized on the host that is meant to act as a software switch, it has not been configured yet. There are two main things that need to be configured : ''create your software switch with the interfaces as ports'' and ''point the switch to an OpenFlow controller''. In order to configure our switch, we first need to login to the host that will be used as an OpenFlow switch. == Login to OVS host == {{{ #!html
Login information for a VM
  1. Return to the Slice page. Press the Details button in the row of the slice table for Utah ProtoGENI.
  2. Click on the ssh link. If you have installed FireSSH a new tab will open up.
  3. In the window that will pop up :
    • in the password field type in your passphrase
    • in the private key, browse to the file that has your private key
    • Press OK
  4. If you don't have FireSSH installed, open a new terminal window. Copy the command to the right of Login into that terminal window.
  5. You are now logged in to the OVS host.
}}} == 1. Create the Software Switch == Now that you are logged in, we need first to initialize OVS: * Start the OVS database: {{{ sudo 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 }}} * Initialize OVS: {{{ sudo ovs-vsctl --no-wait init }}} {{{ sudo ovs-vswitchd --pidfile --detach }}} Ignore the warnings you are going to see. Now that OVS is running it is time to create our software switch. The software switch will be a bridge, in which we are going to add all the interfaces we want to be part of the switch. {{{ #!html
