I would love to see a high level overview and compare/contrast between different container and virtualization technologies out there. For those if us who have a good understanding of operating systems and hardware, but haven't been keeping up with the plethora of new technologies that are out there.

From what I understand, even QEMU can work in different modes, either emulating hardware or a system call interface. So I'm not sure which of those modes you are referring to.

QEMU cannot emulate a system call interface with KVM, only with just-in-time compilation. In hardware emulation mode however it can provide multiple hardware models, including one that is rather similar to Firecracker.
