 ## 结论

 - **根因（第五节）**：HVF 的内核态 GICv3 与 QEMU 的 `usb-storage` 有竞态，Windows Setup 每读一批数据就卡约 10 秒。
-  在 `[machine]` 里加 `kernel-irqchip = "off"`（已写入 `qemu/windows11-darwin-arm64.ini`）后，
+  由 `run-windows11.py` 加 `-machine kernel-irqchip=off`（`--install-from-img` 时不加）后，
  **同样走 USB 光驱的 `--install-from-iso` 也变快了**，和 UTM 的速度一致。
 - 下面第一到五节是更早的分析：当时把慢归因于"模拟 USB 光驱吞吐低"（平均约 4 MB/s），
  这个归因不准确，真实原因是上面的 10 秒停顿；那时测到的低吞吐就是停顿拉低的平均值。

The new vmforwards.py parses them, skips rules whose host port is taken and builds the -netdev argument, which every launcher now passes instead of relying on a netdev section in the ini or on -nic. The ini files move to qemu/<vm>/config.ini and qemu/<vm>/<os>-<arch>.ini. The _SSH_PORT / _RDP_PORT variables and --rdp-port / --ssh-port still replace the host port of the SSH and RDP rules.

GuofangandClaude Sonnet 5.5	07a2c6db3e	Skip kernel-irqchip=off when installing with --install-from-img Move the setting from qemu/windows11-darwin-arm64.ini to a -machine option that run-windows11.py adds on macOS arm64 unless --install-from-img is given. The workaround is only needed for usb-storage, which the NVMe install disk does not use, and Setup hangs with the emulated interrupt controller.

GuofangandClaude Sonnet 5.5	2b237bb8b3	Add a tool to switch the Windows display scale between 100% and 200% 81-Toggle-Scale.ps1 writes LogPixels, Win8DpiScaling and AppliedDPI for the current user; the change needs a restart, so the .bat launcher offers to restart at the end. It is picked up by the existing NN-*.bat/.ps1 globs and copied to Desktop\Tools. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>	2026-10-28 15:06:08 +08:00
guofangandClaude Sonnet 5.5	d2fe47c911	Add a --vnc option to run-windows11.py Serves the guest screen over VNC instead of opening a display window. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>	2026-10-28 14:50:14 +08:00
GuofangandClaude Sonnet 5.5	72af276309	Add an update-status tool and copy numbered scripts to Desktop\Tools 80-Get-UpdateStatus-Admin.ps1 prints whether the Windows 11 guest is upgrading or downloading updates (policy, pending markers, services, processes, BITS jobs, update events, network use); the .bat launcher elevates and keeps the window open. The seed ISO and Configure-Windows.ps1 now take every NN-.bat and NN-.ps1, and the first-logon copy goes to Desktop\Tools instead of Desktop\Installers.
