I'm trying to create a 2-node openstack setup. I want the one host to be the controller, network and compute node and the second host to be just a compute node.

I started by doing a packstack allinone install with the external network setup as described at on

I then copied off the answer file and reinstalled the host with Centos 7.

After doing that, I made the following changes to the answser file and reinstalled using packstack --answer-file packstack-answers-20141129-124340.txt. These changes were prompted by what I read at and at


After doing this and rebooting, I can connect to the dashboard on, but I only see 1 compute node / hypervisor there -

When I did the allinone, I had a hypervisor on

My goal is to end up with 2 hypervisors in this setup.

Can anyone point me at how I accomplish this with packstack please?

In answer-file provided by RDO Juno Set up Two Real Node (Controller+Compute) Gluster 3.5.2 Cluster ML2&OVS&VXLAN on CentOS 7
Make update:-


Next :-

packstack --answer-file=TwoNodeVXLAN.txt`

is supposed to run just once on (Controller && Network Node&&Compute Node)
Up on the packstack completition, will both work as Compute Nodes.
Service openstack-nova-compute.service will be up and running on both nodes mentioned in answer-file.

Comments states that it does not install nova-compute service on Controller. Does simply adding the second IP make this happen ? If so, what's wrong with the way I've done it in my answer file shown in my question ?

Yes, just


may include Controller, then it becomes a Compute Node, may not for production environment.

What I did is standard RDO MultiNode deployment via correct answer-file design. I learned it from Andrew Law posting a while ago, when reproduced his schema on my hosts for RDO Havana.
