Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run fusor-undercloud-installer
2. at "Set your resolvable Fully Qualified Domain Name:", see default value is localhost.localdomain
3. at "Enter the DNS nameserver to use for the Overcloud", see default value is 127.0.0.1
To not provide a default value for these items, in case users just press Enter to all the questions.
My understanding is that if these default values are used, the undercloud will install successfully, but later on, when user deploys an OSP deployment (during node registration), there will be issues.
