Nova does not currently have support for neutron ports without an ip.

when support was added for the neutron port ip_allocation polices only support
for intimidate and defer where implemented.

i believe work is planned to add support for addresses port in train but
i am close this as invalid as it had never been supported.

Title:
  Failed to create VM with no IP assigned to SR-IOV port

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description
  ===========
  Failed to create an instance because of a port attached with no IP address assigned. The port is created over a flat network mapped to a SR-IOV interface.

  Steps to reproduce
  ==================
  A chronological list of steps which will bring off the
  issue you noticed:

  1. Create network

  openstack network create --provider-physical-network physnet1
  --provider-network-type flat sriov-net

  
  2. Create port 

  openstack port create --network ******** --vnic-type macvtap (direct)
  --no-fixed-ip sriov-port

  
  3. Create 

  
  openstack server create --image cloud.img --flavor your_flavor --key-name ssh-key --port sriov-port vm_name


  Expected result
  ===============
  The instance should start with a layer 2 interface configured over a sr-iov virtual function.

  Actual result
  =============
  Port 6dca94cb-1ed5-4131-bc69-4736db5f9f18 requires a FixedIP in order to be used. (HTTP 400)

  Environment
  ===========
  1. Openstack Rocky managed via Juju and deployed using MAAS.

    
  2. Which hypervisor did you use?
     Libvirt + KVM
    

  2. Which storage type did you use?
     Ceph

  
  3. Which networking type did you use?
