neutron J subnet required

gistfile1.txt

# Use case: Boot instances to a provider flat network. Upstream physcial router is gateway.
# Host net info is manually assigned (through cloud-init).
# Current neutron model associated an address from this network even if dhcp is set to false.
# This causes confusion to the cloud user/admin becase the cloud-init manual address differs
# from address in nova list output.
