You mean I wont need to specify any Red Hat subscription and it would let me do the "subscription-manager register" without any userid/ password ?
Also the Lab video"Lecture: RHEL7 Workstation Setup with KVM" - mentions the Server with 28GB RAM, whereas we are limited with 8GB RAM maximum. I am not sure how the instructions align with the Lab availability. I will keep giving you feedback but basically I am doubting anyone used this course to complete the Lab at all ?
If you're using the actual Red Hat products you will need to have the appropriate subscriptions. If you use Open Source alternatives they have their own installation methods. As far as the labs, the course is designed to be installed on local bare metal as more resources are required then the labs can provide and the course does go over this.
