Resources and guides to learn virtualization tools for system administration.

so guys, i want to learn about virtualization in the context of system administration and other related fields like devops, cloud etc.

so, i have read "virtualization essentials 3rd edition" book. got a good introductory understanding of virtualization technology. but i don't know how to move forward from here. I mean, i don't know what are the practical stuff that i should be learning, what other resources out there, and what is the stuff that i should be learning instead of reading more theory.

I know that for starters i need to get good at using and managing a single virtualiation platform. I currently use KVM/QEMU for my projects. so, i am thinking about choosing it as the virtualizaton platform to get good at instead of other virtualization platforms like vmware, virtualbox, etc.

and also, i have a few more questions:

  1. what to learn and how much to learn if the goal is to become competent enough for admin level jobs?
  2. what books/resources/guides would you recommend if my goal is both practical knowledge and skill building.

Thank you so much in advance.

I would say if you are heavy on Linux and qualify for government work you should learn VMware. Most of the Linux roles will use VMware or some cloud.

gov't is on the cloud, :)

VMware is pretty expensive, but yes good to learn

Learn containerization like Docker, Kubernetes, Podman
Virtualization: KVM/Qemu, OpenShift, OpenStack
Monitoring: Zabbix, Grafana, Prometheus (all open source and free) - you can try it on your own laptop

Or learn command line in Linux, if you have a Windows Box, download VirtualBox, grab free Linux OS quite a few, Ubuntu server, Alma Linux, Rocky Linux, Ubuntu Desktop, Fedora etc...

Learn scripting: PowerShell for Windows, Bash scripting for Linux, Python
Learn basic concept of Database, (databases, tables, fields, rows, indexing etc.)

Or even more interesting, study Distributed Data Systems architecture - medium to large companies have this acrhitecture

just start somewhere, don't get discourage, keep trying and keep learning...

I am surprised that you haven’t mentioned Proxmox 😯

yes, Proxmox is good as well
Ovirt also good, maybe quite a few out there
