After all i noticed that even with that ip, i can't build any network.

Instead I will use config drive with flat_injected and
injected_network_template.

Can someone please close this bug?

Title:
  flat network and config drive = no ip

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  I'm not sure if this is really a bug or some missconfiguration from my
  side.

  My configuration:

  flat networking with neutron created with:

  neutron net-create default_net --shared --provider:network_type flat
  --provider:physical_network default_physnet

  neutron subnet-create default_net 10.210.0.0/16 --name default_subnet
  --no-gateway --host-route destination=0.0.0.0/0,nexthop=10.210.0.1
  --allocation-pool start=10.210.25.150,end=10.210.25.244
  --dns_nameservers list=true 10.210.10.1 10.210.10.2 --disable-dhcp

  In nova.conf I have config drive enabled.

  After machine boot, the config drive is attached, but the metadata
  from ec2/latest/ contains local-ipv4: None, so there is no ip for
  cloud-init.

  I had to change this in order to fix it in my case:
  /usr/lib/python2.6/site-packages/nova/virt/libvirt/driver.py

  ## replace
     inst_md = instance_metadata.InstanceMetadata(instance,
                  content=files, extra_md=extra_md, network_info=network_info)
  ## with
     inst_md = instance_metadata.InstanceMetadata(instance, address=network_info[0]['network']['subnets'][0]['ips'][0]['address'],
                  content=files, extra_md=extra_md, network_info=network_info)

  I didn't see in  /usr/lib/python2.6/site-
  packages/nova/api/metadata/base.py how is the address from
  network_info extracted.

  Full info from network_info variable:
