èmm , can you do this on your instance : nova show %instance_Id so that i may see the problem in the resume of spawning ?and are you sure you have enough fixed ip addresses left for use ?

The configuration of nova and quantum is almost the same as me and the instances are getting Fixed Ips without any problem !

All seems alright but not working yet.





http://paste.openstack.org/show/14791/







I have executed on both servers :



ovs-vsctl add-port br-int eth1





Need I do something else ?



How the DHCP is working in this case ?

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


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

        Hi,

        

        

        As I told you, I have also a problem for instance IP assignement.

        

        

        My architecture :

        

        I use Quantum with OVS plugin on 2 servers Essex-1 & Essex-2. Essex-1 runs all services and Essex-2 runs OVS, Quantum-agent & nova-compute only.

        

        You can see more details here.

        

        My configurations files are here and in my documentation.

        

        

        

        Problem Description :

        

        When an instance is created in ESSEX-1, all is working (network).

        

        But when the VM is started on ESSEX-2, it does not get an IP address. (log file)

        

        I'm sure the problem comes from OVS connection with ESSEX-1.

        

        

        Do I need to configure something like a trunk or a tunnel between Essex-1 & Essex-2 ?

        

        I miss something in my configuration, if you have any idea...

        

        

        Regards

        

        

        Emilien

            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. 

            Netstack developers can give a definitive answer to this, but it would be interesting to learn what goes wrong with a launched instance.

                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.

                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. 

                

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

                Hi Salman,

                

                

                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 ?

                

                

                What do you think about my problem (follow up to my last e-mail) ?

                

                

                Thanks

                    Hi,

                    

                    Here is the error log: http://pastebin.com/KrNZDrvD

                    and nova.conf: http://pastebin.com/Fvd6dSZs

                    

                    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.

                    

                    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). 

                    

                    Any ideas?

                    Hi Emilien and Salman,

                    Please, could you upload all the files, errors and conf in pastebin or something like that? 

                    I have troubles to open in phone :)

                        Hi,

                        

                        

                        I have a similar problem when I create a network per project_id with Quantum.

                        

                        

                        My VMs don't get IP and I can't understand why today.

                        

                        But when I create a private network for all projects, VMs get an IP and all is working well.

                        Do you have the same problem ?

                        

                        

                        Salman, I'm interesting about your nova.conf. I can see you are using Ryu ?

                        Can you tell me more about your "use case" or architecture ?

                            Hi Jorge,

                            

                            Thanks for looking into the post.

                            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.

                            

                            Thanks,

                            Salman

                            Im not really sure but you are using range for your environment 10.0.3.x and 10.0.0.x for fixed.

                            Can you attach a nova network conf?
