Title:
  neutron-openvswitch-agent says  Tried to generate an ipset iptable
  rule for a security group rule  even in normal operation

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  Lot's of messages like those ones can be seen in normal operation:

  2015-02-12 20:03:28.775 ERROR neutron.agent.linux.iptables_firewall [req-62cbc788-0fd6-409b-bd52-23634a71b60e None None] Tried to generate an ipset iptable rule for a security group rule ({u'ethertype': u'IPv6', u'direction': u'ingress', u'remote_group_id': u'bead9cb2-9c74-4e21-b219-b70530683193'}) referencing an ipset (IPv6bead9cb2-9c74-4e21-b219) which doesn't exist yet.

  The logic of this log message is broken, and should be removed.

  Because, we can actually generate an iptable rule referencing a set which doesn't exist yet,
  as long as we don't try to push the iptables before creating the sets, in which case 
  iptables-restore would fail, and that's ok enough.

  I will submit a patch to remove the message logic.
