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>
<BR>

<FONT SIZE="2"><FONT COLOR="#366092">Emilien, I am trying to get an understanding of how different Quantum plugins work with OpenStack. Ryu plugin is particularly interesting as it uses an OpenFlow controller to configure Vswitches.</FONT></FONT><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>
<BR>

<FONT COLOR="#366092">Hi Jorge,</FONT><BR>
<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>
