VM unable to connect to virtual switch : vif_type: binding_failed

edit

Hi again, I followed the tutorial of neutron-hyperv-Agent until the end and after the creation of the new VM, it was successfully created and the hyper-v manager shows me the VM which was created through by Openstack. However, When I'd like to check for the vNIC of the VM, I found it not connected. After that, I followed the troubleshooting and I reached until neutron port-show $PORT_ID then I got :
