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.

Is it good to think of libvirt as a virtual machine mointor, or is that more "virtual machine management"?

I'd love to get a clear explanation of what libvirt actually does. As far as I can tell it's a qemu argument assembler and launcher. For my own use-case, I just launch qemu from systemd unit files:

Raises a few questions to me:

Can you use KVM/do KVM stuff without QEMU?

Can you do libvirt stuff without QEMU?

Hoping the answers to both aren't useless/"technically, but why would you want to?"

Here's a post of someone using KVM from Python (raw, without needing a kvm library or anything): https://www.devever.net/~hl/kvm
