Hi Jason,

Thank you very much for your answer.
The problem about the wrong ip address is solved now! Perhaps this
octect should be excluded automatically by nova at the network
creation time?

Regarding the other problem about nova/melange, in fact, I creates all
my networks with the nova-manage command:
nova-manage network create --label=public
--project_id=def761d251814aa8a10a1e268206f02d
--fixed_range_v4=172.16.0.0/24 --priority=0 --gateway=172.16.0.1
But it seems that the nova.fixed_ips table is not well filled.

Thanks again,
Jérôme
