Public bug reported:

Using latest neutron [1] and python-neutronclient [2], we are now able
to create VMs without IP addresses.

If I run :

$ openstack network create net1
$ openstack port create --network net1 port_net1

I get the IP_allocation field equal to "none" for the created port.

So the following command should result in a VM without IP Addresses :

$ openstack server create --flavor 1 --image 78ee2490-3b59-4c1f-
bc29-cdb878ccfc26 --port port_net1

Instead I have the following error :

Port c1013516-8e00-4f99-817d-07edbb386142 requires a FixedIP in order to
be used. (HTTP 400)

It seems that nova only accepts VMs with deferred ip_allocation [3][4],
not "none".

Accepting "none" as a valid option for the ip_allocation attribute would
implement [5], as [4] was expected to, regarding Matt Riedemann last
comment on [5].
