often called a bare-metal hypervisor
|
Detailed explanation-1: -The most commonly deployed type of hypervisor is the type 1 or bare-metal hypervisor, where virtualization software is installed directly on the hardware where the operating system is normally installed. Because bare-metal hypervisors are isolated from the attack-prone operating system, they are extremely secure.
Detailed explanation-2: -A Type 1 hypervisor runs directly on the underlying computer’s physical hardware, interacting directly with its CPU, memory, and physical storage. For this reason, Type 1 hypervisors are also referred to as bare-metal hypervisors. A Type 1 hypervisor takes the place of the host operating system.
Detailed explanation-3: -When a hypervisor is installed directly on the hardware of a physical machine, between the hardware and the operating system (OS), it is called a bare metal hypervisor. Some bare metal hypervisors are embedded into the firmware at the same level as the motherboard basic input/output system (BIOS).
Detailed explanation-4: -A Type 1 hypervisor runs on bare metal and a Type 2 hypervisor runs on top of an operating system.
Detailed explanation-5: -A few examples of Type 1 hypervisors are Citrix/Xen Server, VMware ESXi and Microsoft Hyper-V. While considered efficient and well performing, these hypervisors are also known to be very secure.
