Yes, Raja is correct.

These instructions you are pointing to are for using Quantum, which I
believe is your goal based on past emails.  However, the traceback below
seems to imply that nova-manage is picking up a flag file that does not
specify that Quantum Manager is to be used (hence it is loading some other
network manager, which is giving you the duplicate VLAN error).
