Hello Sebastien, What you can do today is to choose manually which floating IP you need to associate with a specific instance. You need to run OpenStack Folsom + Quantum. First, you need to create Floating IP pool(s) from Quantum CLI, and after that, the tenant is able to associate this IP to a private instance : quantum floatingip-create ext_net quantum floatingip-associate $FLOATING_ID $PORT_ID More informations about Networking configuration with Quantum CLI here : http://docs.openstack.org/trunk/openstack-network/admin/content/demo_logical_network_config.html Cheers ;-) Emilien Macchi ---------------------------------------------------- // eNovance Inc. http://enovance.com // ✉ emilien at enovance.com ☎ +33 (0)1 49 70 99 80 // 10 rue de la Victoire 75009 Paris ----- Mail original ----- De: "Sébastien Han" <han.sebastien at gmail.com> À: "Openstack" <openstack at lists.launchpad.net> Envoyé: Lundi 29 Octobre 2012 17:25:47 Objet: [Openstack] Allocate specific floating IP to an instance Hi Stacker, I know OpenStack is not designed that way and I don't think it's possible (or maybe I misses something :)) but I was wondering if there is any simple workaround to choose a specific floating IP to allocate. In other words, don't give me a random or N+1 next floating IP available but let me decide which floating IP I want to assign to my instance. It doesn't make sense in a public cloud but it does for a corporate/private cloud. It would be nice to have :) Thanks in advance.
