Hi all,

I followed the Grizzly Multinode howto 
(https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst), 
but could not make Quantum operational. I apologize in advance for the 
long email, but I was hoping that someone can help me with this setup.

To make it as easy as possible, my setup env is absolutely the same: I 
have the Controller, Compute and Network nodes, which are connected to 
each other as described. The only difference is "VM Internet Access" IP 
address. Instead of 192.168.100.0/24, my range is 192.168.0.0/16, and I 
gave 192.168.1.0/24 to OpenStack nodes. OS is Ubuntu Server 12.04 
x86_64. Just to make it clear, my company's network is organized like 
this:

[Public IP: 212.200.x.x] <-> Router (gateway: 192.168.0.3) <-> 
[192.168.0.0/16] <-> [our workstations: 192.168.0.0/24]
							  			    [openstack nodes: 192.168.1.0/24]

Regarding nodes' configuration, I followed the same steps as howto 
suggested, changing only IP addresses where needed (ie, 10.10.10.51 -> 
10.10.10.201, etc). Everything went fine and without errors, so I came 
to "5. Your first VM". Since I'm still struggling to understand 
Quantum's fundamentals, I am not sure whether I did something wrong from 
now on. For this first steps with OpenStack, my goal is to be able to 
create a VM and to give it IP address from 192.168.1.0/24 pool, so I can 
ssh to it from my workstation, for example. Of course, it would be nice 
to allow that VM access to the Internet (public access to that VM is not 
necessary for now).

So, I created the new tenant and network for it. The subnet for tenant 
network I created like this:

# quantum subnet-create --tenant-id $put_id_of_project_one net_proj_one 
10.10.10.0/24

Next, I created the router and assigned it to the l3-agent and subnet. 
Then, I created ext_net and a subnet for the floating ips, like this:

# quantum subnet-create --tenant-id $put_id_of_admin_tenant 
--allocation-pool start=192.168.1.2,end=192.168.1.199 --gateway 
192.168.0.3 ext_net 192.168.1.0/24 --enable_dhcp=False

Is this correct? Internal network should be 10.10.10.0/24 and external 
192.168.1.0/24, so when I create an instance and associate the IP, lets 
say, 192.168.1.5, it should forward packets to 10.10.10.5..right?

Back to howto, I set the security rules like this (because in nova.conf 
I told it to use Quantum Sec.Groups, not Nova's):
# quantum security-group-rule-create --protocol icmp --direction 
ingress default
# quantum security-group-rule-create --protocol tcp --port-range-min 22 
--port-range-max 22 --direction ingress default

Finally, I logged in Dashboard and created new instance, which was 
successful. But, there are several networking problems:

1. Instance Console Log: wget: can't connect to remote host 
(169.254.169.254): Network is unreachable
2. VM did not receive its private IP (10.10.10.x), so it is not 
pingable

So, I would appreciate it if you could tell me what could be the 
potential problems, just to point me in some directions. Feel free to 
ask for logs and configs, I will gladly provide those.

Thanks in advance.
Best regards,
