Yes, the error relates to that bug: you should pass both --neutron-network-type
vlan and --neutron-tunnel-types vlan to pass.

In addition to this you should also make sure that the network templates
match your physical environment, provide valid vlan range(10009 is not a
valid vlan tag), switch configuration is in place.
