Here my nova.conf and I don't have any interfering DHCP server :<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>

Hi,<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>

<font color="#366092">Thanks for looking into the post.</font><br>
<font 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.</font><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>
