Can you send my your nova.conf of nova-compute servers ?<BR>
<BR>
<BR>
<BR>
I'm thinking about flat interface...<BR>

Basing on your architecture picture , I think you mean ping VM that resides on Essex 2 from server containing Essex 1
</BLOCKQUOTE>
<BLOCKQUOTE TYPE=CITE>
I had a similar networking problem and i honestly don't know i fixed it ( didn't enable tunneling) , this is what i did
</BLOCKQUOTE>
<BLOCKQUOTE TYPE=CITE>
1- ifconfig eth0 0.0.0.0

2- dhclient br-int ( normally the bridge will take the address of eth0)

btw , i used your ubuntu 12.04 LTS cloud img and i can't seem to ping it but when i choose another image ( the default tty for example) it ping as a charm , probably you should pick another image !

èmm , can you do this on your instance : nova show %instance_Id so that i may see the problem in the resume of spawning ?<BR>
and are you sure you have enough fixed ip addresses left for use ?<BR>
<BR>
The configuration of nova and quantum is almost the same as me and the instances are getting Fixed Ips without any problem !<BR>

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

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>

I have troubles to open in phone :)<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>

<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>
