Listen people, Firecracker is NOT A HYPERVISOR. A hypervisor runs right on the hardware. KVM is a hypervisor. Firecracker is a process that controls KVM. If you want to call firecracker (and QEMU, when used in conjunction with KVM) a VMM ("virtual machine monitor") I won't complain. But please please please, we need a word for what KVM and Xen are, and "hypervisor" is the best fit. Stop using that word for a user-level process like Firecracker.

I think people just pick the coolest sounding term. Imagine someone is sharing what they are working on, what’s cooler sounding “I am working on a virtual machine monitor” or “I am working on a hypervisor”. Hypervisor just sounds futuristic and awesome.

It’s like with “isomorphic” code. That just sounds much cooler than “js that runs on the client and the server”.
