I have a question about type 1 and type 2 hypervisors. Type 1 runs on the bare metal, and then the end operating systems are installed on top. This seems to me like the most logical way to build a virtualized environment.
But there's type 2 where a base OS has to be installed first, then the hypervisor, then the end operating systems needed. I don't understand why anyone would go through the trouble of using a type 2. Are there any use cases that justify needing a base OS as it's done in type 2?
