Which hypervisor is classified as a type-1 hypervisor?

The classification of a hypervisor into type-1 or type-2 is based on its architecture and deployment model. A type-1 hypervisor, also known as a bare-metal hypervisor, runs directly on the physical hardware of the host machine. This allows it to manage guest operating systems (VMs) more efficiently, as there is no intermediary layer of a host operating system.

VMware ESXi is a prime example of a type-1 hypervisor. It is designed for high performance and scalability, providing direct access to the hardware resources of the server. This direct access results in lower overhead, improved performance, and better resource management compared to type-2 hypervisors, which run on top of a host operating system. ESXi is a key component of VMware's virtualization solutions and is widely used in enterprise environments for server virtualization.

In contrast, the other options such as VMware Fusion, VMware Workstation, and Oracle VM VirtualBox are considered type-2 hypervisors. These platforms run on top of an existing operating system, which adds an extra layer between the hardware and the virtual machines, potentially leading to greater latency and reduced performance compared to type-1 hypervisors. Type-2 hypervisors are often used for
