Hi,<BR>
<BR>
I know this problem.<BR>
<BR>
You should :<BR>
<BR>
- Delete the network with "nova-manage network delete --uuid=XXXXXXX" (you can find the UUID with nova-manage network quantum_list"<BR>
<BR>
- Clean the ovs_quantum database to check if the network has been deleted<BR>
<BR>
-Clean the nova database and purge all fixed_ips, networks<BR>
<BR>
<BR>
I remember after that, my problems was solved.<BR>
<BR>
<BR>
I hope that's works now for you ;-) -> Let me now !<BR>
<BR>
<BR>
<BR>
Regards<BR>
