That's good question. QEMU operates in three modes: user mode, system mode, and virtualization mode. To avoid using emulation, in the virtualization mode Kernel-based Virtual Machine (KVM) can be used assuming the host and target both have the same architecture.
Great video.
One quick question if QEMU is an emulator then why do it uses KVM (hypervisor)?
