Describe type 1 and type 2 hypervisors.
What will be an ideal response?
ANSWER: There are two types of hypervisors: type 1 and type 2. A type 1 hypervisor runs on “bare metal,” meaning it loads on physical hardware and doesn’t require a separate OS, although many type 1 hypervisors incorporate Linux-based operating systems. Literally thousands of VMs can be hosted on a single type 1 hypervisor and many more on a cluster of these hosts. A type 2 hypervisor rests on top of an existing OS, such as Windows, Linux, or macOS.
