Proxmox virtualization

Hello friends, I am entering the world of server virtualization, if you are interested in sharing your knowledge, I will be very grateful.
At the moment I find myself in a bind, I have little knowledge of Virtualization, but with what I have accomplished the installation and configuration of a server in the company that works, which is already working at a time without problems, but we realize the purchase of another server, so that a cluster can be made with HA in them, at the moment I am studying ways to carry out this procedure, but until the moment I did not get much success, if they can help me with this, thank you in advance everyone.

I’m sorry, I’m not very well. I’m Brazilian.

If you’re learning, I’d recommend just using something free and easy like VirtualBox. Just install it on your computer and you can start playing around with virtual machines.
