I think this documentation explains better like me :
http://docs.openstack.org/trunk/openstack-network/admin/content/Using-dle455.html Quantum is in incubation with Essex, so it's use Nova as a client of Quantum. In the future, Quantum could be able to manage floating / fixed ips by itself. Regards Le jeudi 03 mai 2012 à 17:06 -0500, Salman Malik a écrit : > Hmm...
