I setup an openstack environment using rdo packstack (Newton version). Now I want to expand it by adding an another compute host, there are steps to do that, but in that process, i am facing this issue.

Error: Could not enable iptables: Execution of '/sbin/chkconfig --add iptables' returned 1: error reading information on service iptables: No such file or directory

Could any one suggest me on how to fix this issue. Is there any updates on the packstack version that resolved this issue?.
