Hi Wisam,
You will get this error, when you use Ryu and have OvS installed on the
same machine. OvS will run ovs-testcontroller at system start, which will
prevent Ryu from starting. Kill all the ovs-testcontroller related
processes or issue the following command:
*sudo /etc/init.d/openvswitch-testcontroller stop.*
