We replaced Firecracker with QEMU
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 (&quot;virtual machine monitor&quot;) I won&#x27;t complain.  But please please please, we need a word for what KVM and Xen are, and &quot;hypervisor&quot; is the best fit.  Stop using that word for a user-level process like Firecracker.
