As a newbie to virtualization, I've been putting off the upgrade to 6.7 (from 6.5) for quite sometime for my home lab environment. After watching this video a few times, I decided to follow the steps provided for one of my hosts and it worked like a charm! Thank you so much for your efforts. I'm subscribed to your channel and look forward to more of your videos!
