The main difference between Type 1 and Type 2 hypervisors is that Type 1 runs on bare metal and Type 2 runs on top of an OS. Each hypervisor type also has its own pros and cons and specific use cases. Virtualization works by abstracting physical hardware and devices from the applications running on that hardware.
