As discussed in class, which of the following is NOT a characteristic of a type 1 HyperVisor? No OS logging Most efficient and best performing Higher initial costs Hosted hypervisor
The Correct Answer and Explanation is:
The correct answer is Hosted hypervisor.
Explanation:
A type 1 hypervisor, also known as a bare-metal hypervisor, runs directly on the physical hardware of a machine. It does not require an underlying operating system (OS) to function. This makes it more efficient and performant compared to other types of hypervisors, like hosted ones.
- No OS logging: Type 1 hypervisors don’t depend on an operating system to function. Instead, they directly interact with the hardware, which means they bypass the need for an OS’s logging system. This characteristic ensures that the hypervisor has full control over the machine’s resources.
- Most efficient and best performing: Since type 1 hypervisors operate directly on the hardware, they are typically the most efficient and offer superior performance. There is no OS layer in between the hardware and the virtual machines (VMs), so there’s less overhead and greater resource allocation efficiency.
- Higher initial costs: One of the downsides to type 1 hypervisors is that they often have higher initial costs. This is because they are more complex to set up and maintain, as they require dedicated hardware and more advanced configurations compared to hosted hypervisors.
- Hosted hypervisor: This is the characteristic that does not apply to a type 1 hypervisor. A hosted hypervisor (or type 2) runs on top of a host operating system, which is a major distinction from a type 1 hypervisor. Hosted hypervisors are typically less efficient because they introduce an additional layer between the virtual machine and the physical hardware. The OS handles the interaction between the hypervisor and the hardware, which results in more overhead.
In conclusion, a type 1 hypervisor does not use a hosted OS, making the “Hosted hypervisor” option the correct answer as something that is not a characteristic of a type 1 hypervisor.
