Issue description

In chapter 10, we are not able to deploy the OpenStack data plane.  First, the ansibleHost IP addresses must be updated (which I missed knowing in the lecture): 192.168.50.3{1,2} to 192.168.51.3{1,2}.  This is pointed out in the GE and Lab (step 4).  They also both say that the deployment fails with errors because of an issue in the classroom lab environment.

There must be something else that needs to change in the classroom lab environment.  Does anyone know why the ansibleHost IPs need to change?  Is this something where we built it one way, but we changed something so the student lab environment is different than the build lab environment?

I think this is a blocker, because a student/instructor cannot successfully finish the GE/lab (arguably there is a workaround, which is to let it fail and destroy the entire OpenStack environment, then destroy it and redeploy).  This leaves a really bad impression for the last chapter, like we don't really know what we are doing.

The last sentence in the GE/lab reads:

This error is related to the classroom environment, which you can ignore until it is fixed.

...which I think means:

This error is related to the classroom environment, and not to the OpenStack nor OpenShift products.

You can't really ignore it (as in, if you try to use your environment after you have run the steps to the GE/lab), because if you do, the entire OpenStack environment is no longer working.
