Hi,

I know this problem.

You should :

- Delete the network with "nova-manage network delete
--uuid=XXXXXXX" (you can find the UUID with nova-manage network
quantum_list"

- Clean the ovs_quantum database to check if the network has been
deleted

-Clean the nova database and purge all fixed_ips, networks


I remember after that, my problems was solved.


I hope that's works now for you ;-) -> Let me now !



Regards
