Thanks Arun, Your last sentence is where I am at "The bottom line -- both VB and Proxmox (KVM) are very powerful, you need to figure out your use case and pick the appropriate platform.". I hope to upgrade my desktop and network in 2026... I currently run Kubuntu on an old Dell with an i5 w/ 4 cores and 4 threads. It has 16G of RAM... just barely enough. Good enough for my needs. I am running an old HP laptop that is WIN10 running VirtualBox for development and testing. I run it because it runs my Win only video software. I have a Proxmox server on an old dell as well. I have not use the Proxmox for a while.... There is a person on the list that does everything on his laptop. That is a consideration. I do need a NAS as well. Nothing too extravagant. I need a decent backup and something for file sharing.
