Which statement explains why Type 1 hypervisor is considered more efficient than Type2 hypervisor?
- A. Type 1 hypervisor is the only type of hypervisor that supports hardware acceleration techniques.
- B. Type 1 hypervisor relies on the existing OS of the host machine to access CPU, memory, storage, and network resources.
- C. Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.
- D. Type 1 hypervisor enables other operating systems to run on it.
Explanation: There are two types of hypervisors: type 1 and type 2 hypervisor.
In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server.
Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures.
Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V.
In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer ‘Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS’ big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).
