It looks like port deletion (as a consequence of server deletion) is
racing with the deletion of the default security group. This most likely
happens if Nova does not ensure that the port is indeed gone before
assuming that the server is indeed deleted.

  It looks like the request to delete a security group is processed
  before the request to delete the port using it and thus the conflict:
