This is odd as it should have updated the files.

Can you please update to the following:

network_api_class = nova.network.quantumv2.api.API
quantum_admin_username = quantum
quantum_admin_password = servicepass
quantum_admin_auth_url = http://127.0.0.1:35357/v2.0/
quantum_auth_strategy = keystone
quantum_admin_tenant_name = service
quantum_url = http://localhost:9696/
libvirt_vif_driver = nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver

This may help.

Thanks
Gary
