Lesson 1: Type 1 vs Type 2 Hypervisors

Knowledge

Type 1 (bare-metal): ESXi, Hyper-V, KVM — on hardware, production use. Type 2 (hosted): Workstation, VirtualBox — on host OS, testing/education. Type 2 slower: host OS consumes resources.

MCQ 1: Type 1 hypervisor is also called:

Hosted hypervisor Bare-metal hypervisor Software hypervisor Application hypervisor

MCQ 2: Which is Type 1?

VMware Workstation Oracle VirtualBox VMware ESXi Client Hyper-V

MCQ 3: Why is Type 2 slower?

Uses more network bandwidth Host OS consumes hardware resources Cannot run multiple VMs Requires more disk space

MCQ 4: Type 2 hypervisors are mainly for:

Cloud provider infra Testing and education Mainframe batch jobs Router firmware

T/F: Type 2 is preferred for production datacenters.

T/F: KVM is a Type 1 hypervisor example.

T/F: VMware Workstation is Type 1 bare-metal.

Fill: Type 1 = hypervisor

Fill: Virtualization software layer:

Essay: Compare Type 1 and Type 2 hypervisors.

A hypervisor virtualizes hardware for VMs. Type 1 (bare-metal: ESXi, Hyper-V, KVM) installs on hardware — faster, for production. Type 2 (hosted: Workstation, VirtualBox) runs on host OS — slower because host OS consumes resources, used for testing/education. Choose Type 1 for datacenters; Type 2 for dev laptops.
