Gotcha.
TrevorH, Perfect! That fixed it!
For the Vagrant side of the answer, it was just a matter of destroying the VM and starting fresh, but using THIS image (https://vagrantcloud.com/chef/boxes/centos-7.1) instead of the one that I WAS using (https://vagrantcloud.com/chef/boxes/centos-7.0)
So, like you said 7.1 vs 7.0. Thanks a ton! Have a wonderful day.
