Perform statements :-
$ nova floating-ip-create

$ nova floating-ip-associate test0 172.24.4.3
$ curl http://172.24.4.3
curl: (7) Failed to connect to 172.24.4.3 port 80: No route to host

Then scan via hping3 port 80 at 172.24.4.3

hping3 return packets , it means port 80 is closed.

UbuntuDocker is container launched via docker image Ubuntu Rastasheep (sshd), which worked fine on 02/15/2015 and still working fine on host running stack.sh instance, recoverable between reboots.
In meantime I get :-
