Detailed explanation-1: -A type 1 hypervisor, also referred to as a native or bare metal hypervisor, runs directly on the host’s hardware to manage guest operating systems. It takes the place of a host operating system and VM resources are scheduled directly to the hardware by the hypervisor.
Detailed explanation-2: -The bare metal hypervisor is the most commonly deployed type of hypervisor. This is where the virtualization software is installed directly on the hardware, where the operating system is normally installed. Bare metal hypervisors are extremely secure since they are isolated from the attack-prone operating system.
Detailed explanation-3: -A Type 1 hypervisor is a layer of software installed directly on top of a physical server and its underlying hardware. Since no other software runs between the hardware and the hypervisor, it is also called the bare-metal hypervisor.
