  • Full x86 emulation, from 386 to recent x86-64 CPUs
  • Useful for OS development and low-level debugging
  • Emulates whole machines across processor architectures, not just same-architecture VMs
  • Near native performance when paired with KVM or Xen
  • Much slower than virtualization-based VM software
  • Configuration is text-based and technical
  • Raw QEMU is a command line tool with a large and unfriendly option surface
  • Cross-architecture emulation is far slower than virtualisation on matching hardware
