Not really a bug, moreover a lack of feature, but it is documented: "Networking does not currently support the v4-fixed-ip parameter of the --nic option for the nova command" ( http://docs.openstack.org/admin-guide-cloud/content/advanced_vm_creation.html ).

If you want to specify an IP address you have to use:

$ neutron port-create --fixed-ip subnet_id=SUBNET_ID,ip_address=IP_ADDRESS NET_ID
$ nova boot --image IMAGE --flavor FLAVOR --nic port-id=PORT_ID VM_NAME

As I know, now nova does not support just use '--nic v4-fixed-ip', but it can support '--nic net-id=xxxx, v4-fixed-ip=xxx', now the error happen in neutron-client, so I think this neutron-client bug!

I will investigate if this is also a neutron client issue.. if not, Ill remove the tag

A comment in review 149905 suggests that this could be a duplicate of bug 1396854.

    Transform IPAddress to string when creating port

    If ip address is provided when running nova boot, nova compute
    will invoke neutron client to create a port. However, the ip
    address parameter is an IPAddress object so neutron client will
    fail to send the request to neutron server. Transform IPAddress
    object to string to address this issue.

I test https://review.openstack.org/#/c/158435/ for JUNO 2014.2/2014.2.1, only change request.address to str(request.address) for all nova servers(include controll nodes and compute nodes), it work fine, VM can boot with v4-fixed-ip now!
