In Bare-Metal virtualization, where is the virtualization software installed?

• A. On the host OS
• B. In a separate management VM
• C. Directly on the machine hardware
• D. In the guest VM

Answer: (C)

Bare-metal virtualization means the hypervisor runs directly on the physical hardware, with no host operating system in between. This direct-on-hardware placement gives a Type 1 hypervisor its low overhead and strong isolation, letting each guest VM access CPU, memory, and I/O efficiently. If the virtualization software were installed on a host OS, you’d have a hosted hypervisor sitting atop an OS, adding extra layers and reducing performance. A separate management VM would imply managing the environment from inside another VM, which isn’t the bare-metal model. Nested virtualization, where the hypervisor runs inside a guest VM, adds even more complexity and latency. So the virtualization software sits directly on the machine hardware.
