Title:
  Security groups incorrectly applied on new additional interfaces

Status in neutron:
  Invalid
Status in OpenStack Compute (nova):
  Opinion

Bug description:
  When launching an instance with one network interface and enabling 2
  security groups everything is working as it supposed to be.

  But when attaching additional network interfaces only the default
  security group is applied to those new interfaces. The additional
  security group isn't enabled at all on those extra interfaces.

  We had to dig into the iptables chains to discover this behavior. Once
  adding the rule manually or adding them to the default security group
  everything is working fine.
