How to disable firewall on OEL 6

Problem : Firewall not disabled on OEL 6 after running chkconfig iptables off and system reboot

 
To fix the problem you need to disable libvirtd 
# chkconfig libvirtd off
# chkconfig libvirt-guests off
# chkconfig ip6tables off
# chkconfig iptables off

#  chkconfig --list  | egrep 'iptables|ip6tables|libvirt'
ip6tables       0:off   1:off   2:off   3:off   4:off   5:off   6:off
iptables        0:off   1:off   2:off   3:off   4:off   5:off   6:off
libvirt-guests  0:off   1:off   2:off   3:off   4:off   5:off   6:off
libvirtd        0:off   1:off   2:off   3:off   4:off   5:off   6:off

After a reboot  the firewall should be disabled now
[root@grac43 ~]# service iptables status
iptables: Firewall is not running.
