Technical requirements

All the practice exercises in this chapter require the use of a virtual machine (VM), running Red Hat Enterprise Linux 9 (RHEL 9) installed with the base installation. Additionally, new virtual drives will be required for storage operations.

For the exercises, it is assumed you possess the following:

RHEL 9 installed with the base operating system using the Minimal Install software selection.
Access to the Red Hat Customer Portal, with an active subscription.
The VM must be expendable. This is because actions performed on it during the exercise might render it unusable and require it to be reinstalled.
