[Ale-study] Virtualization?

[John]

The answer is "it depends."  I'm happy to discuss the VM options with 
anyone on a call.  The best answer depends on your hardware, the clients 
to be installed, any host OS plans, how you plan to perform backups, 
stability needs, whether you have another PC to use for VM management, 
and a few other considerations.

Below it says, "

Setting up a new VM server environment
today on Linux for Linux VMs, I'd use KVM.

"
That is my best advice, lacking any additional information.
