Called a hypervisor but is really a VMM
From 2 comments
Why do you call it a hypervisor when it's more like a VMM? Even the name "VMM" is a quirk of KVM; before KVM, "virtual machine monitor" was another name for a hypervisor: that…

An excellent example is Marcan's m1n1 hypervisor. He uses it to boot MacOS to inspect interactions between the OS and hardware calls. Part of his efforts to have native linux on…
