> i am talking about bare metal, but dynamic hardware resources would require some sort of virtualization This is a bit confusing, as "bare metal" is usually used as a contrast to virtualization, although it I suppose it could mean "not cloud" (but further muddled by AWS offering "bare metal" instance types). More importantly, though, if you're thinking of some kind of VPS provider, where you'd dynamically allocate and de-allocate servers from their inventory, there's no reason you couldn't run directly on the hardware with no hypervisor. Virtualization is only strictly necessary for multi-tenancy, such as if you need to allocate only half of a server.
