We noticed the same thing.  It a simple patch in /nova/virt/netutils.py (we have been running this since icehouse).

Below is our current patch for kilo.

When you create the network you need to set dhcp to false, otherwise, no static ip in config drive.

I have an icehouse openstack setup.

I have the following lines in nova.conf:

force_config_drive = always
config_drive_cdrom = True

Whenever I launch an instance, I can see a content directory in the config drive

openstack/content/0000 contains all network interfaces.

I can simply configure the static IP address from openstack/content/0000.

Now I have a new openstack cluster setup and I cannot see this content directory when I launch a VM.

I checked my configuration files and I can't find any difference with my old cluster.

Any ideas?
