I believe this does not affect Ironic, as there is validation of MAC
addresses done within the db/api layer, which was not done by Nova.

I will re-open if it is demonstrated that one can create an invalid or
empty mac address in Ironic, leading to similar failures.

** Changed in: ironic
       Status: New => Invalid

Title:
  baremetal allows to register an interface having an empty mac address

Status in Ironic (Bare Metal Provisioning):
  Invalid
Status in OpenStack Compute (Nova):
  In Progress

Bug description:
  It leads a network manager to create an invalid entry in dnsmasq's
  hostsfile, like:

  ,bm.novalocal,10.0.0.2
  (The first column is a mac address. In this case, the instance never receive 10.0.0.2)

  In addition, once such a interface is added, we cannot delete it.

      $ nova baremetal-interface-remove 1 ''
      ERROR: Must specify id or address (HTTP 400) (Request-ID: req-d0631fc4-361d-43fa-870a-82e077cd454b)
