No, I don’t agree, not necessarily. VMs are “heavier” as in use more disk and memory but if they are mostly idling and in a small lab you probably won’t notice the difference. Now if you are running 10 services and want to put each in its own vm on a tiny server, then yea, maybe don’t do that.

In terms of cpu it’s a non-issue. Vm or docker they will still “share” cpu. I can think of cases I’d rather run proxmox and others I’d just go bare metal and run docker. Depends on what I’m running and the goal.
