What are two characteristics of a type 1 hypervisor?
(Choose two)
a. The VM resources are scheduled using the host hardware.
b. The hypervisor runs directly on the underlying host OS.
c. The VM resources are scheduled using the host OS.
d. The hypervisor runs directly on the host hardware.
The Correct Answer and Explanation is :
The correct answers are:
a. The VM resources are scheduled using the host hardware.
d. The hypervisor runs directly on the host hardware.
Explanation:
A Type 1 hypervisor, also known as a “bare-metal” hypervisor, is a virtualization platform that runs directly on the physical hardware of the host machine without the need for an underlying operating system. It operates as the host operating system itself, providing a dedicated environment for managing virtual machines (VMs). This gives it several advantages in terms of performance, security, and stability.
- The hypervisor runs directly on the host hardware (option d):
Type 1 hypervisors are installed directly on the physical server hardware. The absence of a host operating system between the hardware and the hypervisor helps to minimize resource overhead, allowing better resource utilization for virtual machines. Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V, and XenServer. - The VM resources are scheduled using the host hardware (option a):
Since the Type 1 hypervisor runs directly on the hardware, it is responsible for directly managing the allocation of resources (like CPU, memory, and storage) to the VMs. The hypervisor handles all resource scheduling without relying on an underlying host OS. This direct interaction with the hardware ensures efficient use of system resources and improves the overall performance of the VMs.
On the other hand, Type 2 hypervisors (hosted hypervisors) require an operating system to run, and they interact with the host OS to schedule and allocate resources for the VMs. This additional layer introduces more overhead, making Type 2 hypervisors less efficient compared to Type 1 hypervisors.
Now, I will generate an image to illustrate the architecture of a Type 1 hypervisor.
Here is a diagram illustrating the architecture of a Type 1 hypervisor. It shows how the hypervisor runs directly on the physical hardware and manages virtual machines without relying on an underlying operating system. The diagram highlights how the hypervisor handles resource allocation for each virtual machine.
