in the log in the comment #1, the backend (midonet) is complaining about the mac address "FA-16-3E-29-79-FB".

mac_addresses for create_port should be like "fa:16:3e:dd:58:7b".

i added neutron because the change seems unintended.

This is a relic of the shift to using the Port OVO object, which uses netaddr.EUI instead of string for MAC address. The dashed form is it's default translation to string. Let me see how I can go about fixing that.

    Format generated MAC addresses using eui48.mac_unix_expanded

    In Ml2Plugin.create_port_bulk, the MAC generated using netaddr.EUI
    have the following format:
      "XX-XX-XX-XX-XX-XX"

    In order to make them more compatible with other systems, the
    following format is more appropiate:
      "00:01:23:45:67:ab"

    eui48.mac_unix_expanded formater will add leading zeros if needed.

    Ensure that bulk port dicts have unix-style MAC addresses

    The bulk port code uses the Port OVO object, which encodes MAC address
    as a netaddr.EUI object. The default string representation for a
    netaddr.EUI object is the standard IEEE EUI-48 format
    ("XX-XX-XX-XX-XX-XX") [1]. Having MAC addresses in that format breaks
    the midonet gate, so revert to UNIX standard mac addresses
    ("xx:xx:xx:xx:xx:xx").
