You can use proxmox to do most of this. Currently my set will only pass-through the gpu to one VM. I have heard of splitting the power among VMs but I have not gone down that rabbit hole. If I want to play with llms I fire up that server, if I want to game, I shut that down and fire up my windows 10 vm.
It the later was the case then they would make the encryption keys public and they could continue to use new technology all they want.
