Re: Instance IP assignment problem

 

Hi Jorge,

I tried the parameter but to no avail. Also this post (https://answers.launchpad.net/nova/+question/148445) says that it defaults to my_ip if not specified.
Any other thoughts are much appreciated.

Thanks,
Salman

Hi,

In your conf Dalman I dont see a routing_sourceip and in Emilien's cong yes.
Try with this parameter.

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?

Thanks,
Salman

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 :)

Thank you

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 ?





Thanks

    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

    

    PS: Error log of a launched instance is also attached.

    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?
