VMware on Zorin 18 pro with CentOS 9 or AlmaLinux as Guest OS?

Hello everyone. I searched the forum but couldn't find a specific topic for the questions I'd like to ask you all. I hope I'm in the right section, and if so, I apologize to the administrators.
I'm new to Linux. I've done some testing in the distant past, but not much (RedHat, Mandrake, Ubuntu, Suse, etc.). Now, I'm trying to get down to business after downloading Zorin 18 Pro on my Asus N56VZ (I solved the problem of the corrupt file during the system check when booting the USB stick, a problem I posted in a thread about NVIDIA drivers). Day after day, I'm playing with the command line and have purchased a book to study. I installed VirtualBox, on which I run the same version of Zorin as my host OS, the 18 Pro. I still have to solve the problem of permanently disabling the KVM kernel after each PC reboot. Currently, at every reboot, if I use VB, I run the following command from the terminal: $ sudo modprobe -r kvm_intel kvm_amd kvm and it works.
The book instructs me to download CentOS 8 (as a guest OS on VMware Workstation PRO), but we know this version's lifecycle has expired. Now I'm at a crossroads, trying to follow the book's instructions as closely as possible: download CentOS 9, which is an older version of RHEL and therefore not as stable as version 8, or download AlmaLinux, which is 100% compatible with RHEL and faithfully follows its steps. Naturally, what I just wrote suggests that AlmaLinux is the best choice, but I'd like to know if anyone has had a similar experience and, based on their choice, if they were happy with it. Thanks everyone.

Do not follow the steps of the book blindly, otherwise you are not learning anything. The idea is that you understand the steps you're taking, and when it makes sense to change them.

This type of situation is pretty common in the real world. For instance, CentOS 8 was supposed to provide 10 years of support, but RedHat pulled the rug and that caused a lot of people to reassess their needs.

I would go with Alma Linux and adapt the steps from the book. It's all part of the learning process.

Hi @zenzen, thanks for the reply. Yes, I agree with everything you wrote. The fact is that the main path of the book based on an OS type, I would have a clearer explanation of the command than the answer. It's not a limitation, I agree. But in the end I can't download CentOS 9 because have problem during the download AlmaLinux doesn't run on VMWARE, at least for the hardware of my machine (I think that's the problem). I'll try to mount it on Virtualbox where I already have many distributions that I'm practicing with. I'll follow your advice. I'll try to follow the book in general terms, but I'd say that, at this point, I'll refer to other books that are certainly more focused on my current needs. Thanks again for the support. I'll leave the post open in case anyone wants to add something to the discussion or recommend a book I'm not familiar with. Then in a few days I'll tag the title of the post as SOLVED.
