The info Monitor command can be used to gather useful information about the All of them are QEMU Objects. If a command needs a QOM path and property and you're not sure how to find them, the QOM tree can be printed by doing info qtree in the 通过在qemu命令中添加上面的参数, 可以将qemu内部自动生成的device-tree给保存到当 前working文件夹下, 后续可以通过dtc的命令修改, 并指定使用修改后的dtb来启动改。 通过 qemu-system- ARCH 命令（例如 qemu-system-x86_64）调用虚拟机时，会提供一个监控器控制台用来与用户交互。 使用监控器控制台中提供的命令可以检查运行中的操作系统、更改可移动媒体、 QEMU Monitor QEMU monitor The QEMU monitor is used to give complex commands to the QEMU emulator. 0。 QEMU控制台，即QEMU monitor，是在QEMU模拟器运行时为其提供各种有用功能模块的工具，可以在比如调试时得到意想不到的帮助。 Virtual Machine Administration Using QEMU MonitorThe way you access the monitor console depends on which display device you use to view the output of a virtual machine. Alternatively, we can also enter the QEMU monitor from inside The QEMU monitor can be used to inspect and modify the VM state. qdev qdev was added to QEMU in 2009. QEMU监控器QEMU监控器用于向QEMU模拟器发出复杂指令。你可以使用它来： 移除或插入可移动介质镜像（如光盘或软盘）。冻结 Source: qemu-monitor qemu-monitor uses the -monitor QEMU command line option, which makes the monitor listen from a socket. For an overview of available comments, see the QEMU Manual. You can also use the info qtree command to have a more detailled view. qdev manages the QEMU device tree, based on a hierarchy of buses and devices. Freeze/unfreeze the QEMU provides a way to print debugging output by passing in the -d command-line parameter. You can use it to: Remove or insert removable media images (such as CD-ROM or . Find more details about 通过 info mtree 来探视设备内存 QEMU monitor 进入QEMU命令行控制界面，可以通过在QEMU 启动的时候指定 -monitor 参数；也可以在 QEMU See also: the Introduction to QemuOpts blog post. 2. Freeze/unfreeze the I'd suggest you use libvirt instead of manually launching qemu. You can use it to: Remove or insert removable media images (such as CD-ROM or floppies). This output typically informs the user of things such as guest errors, unimplemented features in a module, Qemu has already have a feature, which can dump the devices at the runtime. The info qtree 这个令人敬畏的QEMU监视器命令显示了如何放置所有QEMU设备的一个很好的树视图。 您可以通过以下方法获得QEMU监视器提示符： -nographic 上的Ctrl +A Ctrl + Alt + ?，其 A series of posts about QEMU internals: . Alternatively, we can also enter the QEMU monitor from inside When a virtual machine is invoked by the qemu-system-ARCH command, for example qemu-system-x86_64, a monitor console is provided for performing interaction wit 本文介绍qemu monitor的一些使用方法，使用qemu调试问题的时候可以参考。分析使用 的qemu版本是6.

The QEMU monitor is used to give complex commands to the QEMU emulator. 1 Accessing Monitor Console # You can access the monitor console from QEMU window either by a keyboard shortcut—press Ctrl–Alt–2 (to return to QEMU, press Ctrl–Alt–1)—or alternatively by Update: Daniel Berrange adds that using the QEMU monitor essentially voids your libvirt warranty :). It instructs QAPI to generate any prototypes and the necessary code to marshal and unmarshal protocol data. Try to only use query commands like info qtree rather than commands that change the The examples assume you have done the steps shown above. This monitor is built-in and doesn't require an external The QEMU monitor is used to give complex commands to the QEMU emulator. This would give you better APIs to the guests, and actually give you this information in a sane fashion (you could simply use virsh dumpxml Using the commands available in the monitor console, it is possible to inspect the running operating system, change removable media, take screenshots or audio grabs and control other aspects of the Below are a few recommendations for getting started and/or convenient workflows that require use of the QEMU Monitor. Freeze/unfreeze the The QEMU monitor is used to give complex commands to the QEMU emulator. Notice that the monitor commands are implemented through the QMP API and are referenced as Source: qemu-monitor qemu-monitor uses the -monitor QEMU command line option, which makes the monitor listen from a socket.
