Zorluk: OrtaType 1 and Type 2 Hypervisors

A network administrator is maintaining a workstation used to host several test environment virtual machines. When the administrator reboots the underlying host operating system to apply security updates, all virtual machines are forcibly shut down because the virtualization software operates as an application layer on top of the host operating system. Which hypervisor architecture is deployed on this workstation?

  1. Type 2 hypervisorCevap
  2. B
    Type 1 hypervisor
  3. C
    Infrastructure as a Service
  4. D
    Software as a Service

Cevap

Type 2 hypervisor
The correct answer identifies a Type 2 hypervisor because it runs as an application on top of an operating system. Rebooting or patching the primary host operating system stops the hypervisor software and brings down all hosted virtual machines.

Adım Adım Çözüm

1
Analyze the virtualization environment structure in the scenario.
The virtualization software is installed as an application on top of an existing host operating system.
This indicates an intermediary OS layer exists between the physical hardware and the hypervisor software.
2
Evaluate the cause of the virtual machine shutdown.
Rebooting the host operating system terminates the underlying hypervisor application, which forcibly stops all running guest virtual machines.
Hosted hypervisors rely entirely on the host OS kernel for system services and CPU/memory scheduling.
3
Identify the corresponding hypervisor architecture.
A hypervisor dependent on a host operating system is classified as a Type 2 hypervisor.
Type 1 hypervisors operate directly on host hardware (bare metal), whereas Type 2 hypervisors operate hosted on top of an existing OS.

Anahtar Kavram

Type 2 hypervisors run as software applications on top of a primary host operating system, making guest virtual machines reliant on host OS availability.
