Open Stack

Hi, 

I just got a manual install/conbfiguration of openstack Juno up and running under Ubuntu 14.04 as a POC. 

POC-details: 

    • 1 controller node 
    • 1 network node 
    • 1 compute node 
    • ceph-storage 
    • neutron vxlan-config 

Here extra detailed info of what we have configured in neutron and nova:

The problem with our instance is that it does not get the default gateway configured correctly. 

During startup of the instance I could see following messages:
