QEMU: Emulating Your Way to Success
summary
Codethink uses QEMU to run system-level emulation for CI and development, integrating with openQA and LAVA to boot full images and catch roughly 80% of regressions without hardware. QEMU’s QMP socket and GDB server drive automation and debugging; TCG and KVM tradeoffs affect speed. A custom machine model lets four developers work before silicon ships (prototype FPGA boards cost more than a family car), but RISC‑V atomic-memory quirks and upstream/legal barriers mean emulation is useful but not perfectly accurate.
