<p class="MsoNormal">Hi,<br>
<br>
<br>
As I told you, I have also a problem for instance IP assignement.<br>
<br>
<br>
<u>My architecture :</u><br>
<br>
I use <b>Quantum</b> with <b>OVS plugin</b> on 2 servers Essex-1 & Essex-2. Essex-1 runs all services and Essex-2 runs OVS, Quantum-agent & nova-compute only.<br>
<br>
You can see more details <a href="https://github.com/EmilienM/doc-openstack/blob/master/Documentation/How%20to%20setup%20OpenStack%20Essex.pdf">
here</a>.<br>
<br>
My configurations files are <a href="https://github.com/EmilienM/doc-openstack/tree/master/Configuration%20Files">
here</a> and in my documentation.<br>
<br>
<br>
<br>
<u>Problem Description :</u><br>
<br>
When an instance is created in ESSEX-1, all is working (network).<br>
<br>
But when the VM is started on ESSEX-2, it does not get an IP address. (<a href="http://paste.openstack.org/show/14775/">log file</a>)<br>
<br>
I'm sure the problem comes from OVS connection with ESSEX-1.<br>
<br>
<br>
Do I need to configure something like a trunk or a tunnel between Essex-1 & Essex-2 ?<br>
<br>
I miss something in my configuration, if you have any idea...<br>
<br>
<br>
Regards<br>
<br>
<br>
Emilien<br>

Hi Salman,<br>
<br>
<br>
I'm thinking about a networking issue. Where is your L3 gateway in this architecture ? Maybe do you need an ip helper tool to redirect DHCP broadcast ?<br>
<br>
<br>
What do you think about my problem (follow up to my last e-mail) ?<br>
<br>
<br>
Thanks<br>
<br>

Hi Emilien and Salman,<br>
Please, could you upload all the files, errors and conf in pastebin or something like that?
<br>
I have troubles to open in phone :)<br>
Thank you<br>

<br>
<br>
I have a similar problem when I create a network per project_id with Quantum.<br>
<br>
<br>
My VMs don't get IP and I can't understand why today.<br>
<br>
But when I create a private network for all projects, VMs get an IP and all is working well.<br>
Do you have the same problem ?<br>
<br>
<br>
Salman, I'm interesting about your nova.conf. I can see you are using Ryu ?<br>
Can you tell me more about your "use case" or architecture ?<br>
<br>
<br>
Thanks<br>

<span style="color:#366092">I have made changes to the nova.conf file so that I only use 10.0.0.x network (but the problem is still the same). For this configuration, I assume that it will give out IPs to instances starting from 10.0.0.11. And just to inform
you, my eth1 is configured to be 10.0.0.10 (which is a VM itself, and eth1 is configured as a host-only network with no DHCP) and this interface is plugged in the integration bridge used by quantum plugins.</span><br>

Im not really sure but you are using range for your environment 10.0.3.x and 10.0.0.x for fixed.<br>
Can you attach a nova network conf?<br>
