Make sure that Open vSwitch is installed, that ovsdb-server is running, and that
"ovs-vsctl show" works correctly.
You may wish to try "service openvswitch-switch start".

Cdt,

Hi,
you can use the following command to create your database:
/usr/share/openvswitch/scripts/ovs-ctl start
any time you needed you can use the following command to restart the connection from your OVS to controller:
/usr/share/openvswitch/scripts/ovs-ctl restart
