QEMU Code Overview slides available

I recently gave a high-level overview of QEMU aimed at new contributors or people working with QEMU. The slides are now available here:

QEMU Code Overview (pdf)

Topics covered include:

  • External interfaces (command-line, QMP monitor, HMP monitor, UI, logging)
  • Architecture (process model, main loop, threads)
  • Device emulation (KVM accelerator, guest/host device split, hardware emulation)
  • Development (build process, contributing)

It is a short presentation and stays at a high level, but it can be useful for getting your bearings before digging into QEMU source code, debugging, or performance analysis.
