I watch your mutil node video careful , use packstack run again and find the problem. I think is bug for RDO
the video ip is
control
10.15.0.7
network
10.15.0.5
compute
10.15.0.2,10.15.0.4
when Lars login network node (10.15.0.5) show the iptables rules, (the pic is come from Lar video.)
have 3 iptabes rules.
I think the last rule
-A INPUT -s 10.15.0.5/32
show change to
-A INPUT -s 10.15.0.7/32
otherwise, I can not login Dashboard. show can not connect to neutron.
