Description of problem:
After running instack-install-undercloud as per the instructions in https://openstack.redhat.com/Deploying_an_RDO_Undercloud_with_Instack you can see this traceback near the end of the log:

Version-Release number of selected component (if applicable):
instack-undercloud-1.0.25-1.fc22.noarch


How reproducible:
100%


Steps to Reproduce:
1. Follow the instructions in https://openstack.redhat.com/Deploying_RDO_on_a_Virtual_Machine_Environment_using_Instack and https://openstack.redhat.com/Deploying_an_RDO_Undercloud_with_Instack
2. Look for errors, warnings and other deprecation messages in .instack/install-undercloud.log


Actual results:
Numerous errors, warnings and deprecation messages. They indicate that there might be a problem somewhere, although I don't know exactly which use cases are be affected (if any).


Expected results:
The log should be clean of errors if they are not real errors.
