I have started a Multi node Setup of the Openstack Havana Installation on Ubuntu 12.04LTS 64bit and here is the architecture which i'm planning for

Horizon Dashboard(Nat- ---->Rabbit MQ(Nat->Neutron(Nat-

I'm using Vmware Workstation for this Setup to get the result set from the keystone through the following command

kgrvamsi@neutron:~$ neutron agent-list

But i get this error

#Connection to neutron failed: Maximum attempts reached

Here is my network Interfaces file

The loopback network interface

auto lo
iface lo inet loopback

auto br-ex
iface br-ex inet static

VM internet Access

auto eth0
iface eth0 inet manual
up ifconfig $IFACE up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down

Can anyone help me out whats the problem behind this?

How looks on Neutron Server Node

    [root@dfw02 neutron(keystone_admin)]$ iptables-save | grep neutron | grep ACCEPT
    -A INPUT -p tcp -m multiport --dports 9696 -m comment --comment "001 neutron incoming" -j ACCEPT
    [root@dfw02 neutron(keystone_admin)]$ netstat -lntp | grep 9696
    tcp        0      0  *               LISTEN      1239/python
   [root@dfw02 neutron(keystone_admin)]$ ps -ef | grep 1239
neutron   1239     1  0 10:22 ?        00:03:39 /usr/bin/python /usr/bin/neutron-server --config-file /usr/share/neutron/neutron-dist.conf --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini --log-file /var/log/neutron/server.log

try restarting neutron: service openstack-neutron restart

service openstack-neutron-dhcp-agent restart

check all your process are running.

Just a side note: this syntax is not present anymore in OpenStack Juno - Ubuntu 14.04 (correct me if I am wrong). Correct syntax is service neutron-dhcp-agent-restart
