A bare-metal hypervisor (Type 1) is a layer of software we install directly on top of a physical server and its underlying hardware.

There is no software or any operating system in between, hence the name bare-metal hypervisor..

What is the drawback of virtualization?

Virtualization has its own drawback: the need to restructure the approach to working with system reliability. Indeed, since several virtual machines are running on the same physical server, failure of the host leads to the simultaneous failure of all VMs and the applications running on them.

Are virtual machines safe?

Virtual machines are an isolated environment from the physical operating system, so you can run potentially dangerous stuff, such as malware, without fear of compromising your main OS. They’re a safe environment, but there are exploits against virtualization software, allowing malware to spread to the physical system.

What are the 3 types of virtualization?
