Multinode setup and instance on one compute does'nt get IP

subha · July 8, 2015, 4:44pm

Hi,

We have setup SUSE Openstack cloud 5 on three nodes(SLES-11 SP3) configured as below

Exclusive admin node (SUSE Crowbar)
Compute node - 1 (nova, cinder and neutron services are deployed on this node)
Compute node - 2 (nova, cinder are deployed on the node)

We have deployed the services and able to launch instances. But the instances hosted on compute node -2 do not get any IP, but we can see from the dashboard the IP being assigned is
192.168.123.5. We haved used openvswitch and gre for neutron deployment through openstack barclamps.

so in brief:

d3c-1e-04-46-f0-3e(Compute node -1) : This node has controller ,cinder ,nova and neutron-server and neutron l3.
We have launched instance and the instance got an ip 192.168.123.6 successfully.

db8-ca-3a-78-d8-62(Compute node -2) : This node has nova and cinder. We are able to launch instance but no IP so far, but dashboard show the as IP 192.168.123.5

neutron agent list:

d3c-1e-04-46-f0-3e is controller-compute-cinder-neutron
db8-ca-3a-78-d8-62 is compute-cinder

Here is the output of ifconfig and ovs-vsctl show

Command on the controller-compute-cinder-neutron node (d3c-1e-04-46-f0-3e):

Hi,

I’m not sure I get your configuration, but I am experimenting with suse cloud 5, too. I’m kind of missing a control node in your environment. Did you follow the deployment guide? The section on barclamp deployment (https://www.suse.com/documentation/suse-cloud-5/singlehtml/book_cloud_deploy/book_cloud_deploy.html#sec.depl.ostack.cinder) says:

I have tried two different setups, both with three nodes like you do. First was with admin and control node (where most of the services run, such as cinder, neutron, nova-controller, etc.) running on SLES11 and compute node running on SLES12. I’ve tried with openvswitch and with linuxbridge, I don’t get the cloud working until now. SUSE Support recommended to stick with linuxbridge, by the way.
Then I tried to install compute node with SLES11, too. Using linuxbridge, I had no troubles at all, everything worked perfectly fine!
So I can’t really say what’s wrong with your configuration, but if you follow the deployment guide, you should get it working, at least if you run compute node with SLES11.

This is a fixed IP, automatically assigned to the instance, but it doesn’t mean that eth0 of your instance really has an IP. Try to login to your instance and see if it has assigned an IP. I have still the same issue with SLES12 on compute node. If the IP injection works, your instance should have the IP in its username already (depending on the image you are using, I use SLES11-SP3 here, too), so it would look something like this: host-192-168-123-27:~ #
I hope this helps.

Regards,
Eugen
