Thank's for your link, but I'm not sure to have to use it now.<BR>
<BR>
<BR>
I have one server with all nova services and another with nova-compute only.<BR>
<BR>
<BR>
Anyway, I'm going to post a new e-mail about my problem.<BR>

When nova-network is on remote host, dhcp requests need to go to remote server. I’ve proposed a fix above.<BR>

I have executed on both servers :<BR>

ovs-vsctl add-port br-int eth1<BR>

Need I do something else ?<BR>

How the DHCP is working in this case ?<BR>

Then the problem isn't in the instance but in the nova-network service , please check if it is working well <BR>
<BR>

as well as give us the output log when you attempt to create a new instance.<BR>

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>

It may help if you can share the log of your launched instance as well. There is a possibility that we both are having the same issue.<BR>
Netstack developers can give a definitive answer to this, but it would be interesting to learn what goes wrong with a launched instance.<BR>

Regarding L3 gateway, I believe its not necessary to have one (as the VM hasn't obtained an IP right now, so it can't talk to anything outside its net), but I am not sure.<BR>
Regarding your problem, do you see any DHCP responses from the DHCP server ? I am asking this because I was having a similar problem earlier where I was getting assigned an IP address no in my desired fixed_network and I believe that was cause by another interfering DHCP server that was replying to discover messages before the nova-network could.<BR>
<BR>
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>

Hi,<BR>
<BR>
Here is the error log: <A HREF="http://pastebin.com/KrNZDrvD">http://pastebin.com/KrNZDrvD</A><BR>
and nova.conf: <A HREF="http://pastebin.com/Fvd6dSZs">http://pastebin.com/Fvd6dSZs</A><BR>
<BR>
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.<BR>
<BR>
The problem I am faced with is (I think ) that I already have a private network and Quantum should assign IP addresses to instances using DHCP. But instances send out discover message on laucnh but never find a DHCP server (although there are 2 dnsmasqs running). <BR>
<BR>
Any ideas?<BR>
<BR>
Thanks,<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>

Hi Jorge,<BR>
<BR>
Thanks for looking into the post.<BR>
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.<BR>
<BR>
Thanks,<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>
