Bare-metal hypervisors, also known as Type 1 hypervisors, are a class of virtualization software that run directly on the host's hardware without requiring an underlying operating system. This direct interaction with the hardware allows for greater efficiency and performance compared to Type 2 hypervisors. The hypervisor itself acts as the operating system for the virtual machines, managing resources such as CPU, memory, and storage, and allocating them to the guest operating systems.

Key characteristics of bare-metal hypervisors include their direct hardware access, which minimizes overhead and maximizes performance. They are typically used in enterprise environments, data centers, and cloud computing infrastructure where high performance, scalability, and security are paramount. Examples of popular bare-metal hypervisors include VMware ESXi, Microsoft Hyper-V, and Xen.

The architecture of a bare-metal hypervisor involves the hypervisor layer sitting between the hardware and the guest operating systems. This allows for strong isolation between virtual machines, enhancing security. Each virtual machine believes it has exclusive access to the underlying hardware, but in reality, the hypervisor is mediating these requests. This abstraction is crucial for enabling multiple operating systems to run concurrently on a single physical server. The ability to provision, manage, and migrate virtual machines dynamically makes bare-metal hypervisors a fundamental component of modern IT infrastructure.
