RDO allinone (havana) with neutron
should iptables be active in RDO allinone 'local' mode where Neutron is installed (not nova network) OR :
the iptables service should be stopped or at least all iptables rules flushed
I am asking this because Openstack VM instantiation in my system (with Neutron) assign IP address to the Instances but the addresses don't 'reach' the instances (VMs) and they do not respond to ping from the controller
Also: the dashboard can be reached only from the browser on the controller ( single node) bot not from outside browser
This site has lots of questions about problems with pings not reaching VMs. Try some of the solutions highlighted there and update the question if you can highlight different problems from the others.
