QEMU Monitor on Windows 10 – CentOS

I’m Ronaldo, Newbie of Stackoverflow.

I’m having a problem, On my PC it’s running Windows 10 Build 1803, Then I installed QEMU, but not only that, I installed the graphical version which is QtEmu.

Then I wanted to virtualize CentOS 3.1, with Disk 1, Disk 2 and Disk 3. But I don’t know how to eject the disk in QtEmu, I tried it in PowerShell and I couldn’t, not even in CMD, just the serial0, and the keyboard is not works, only on the PC that works. the Mouse is ok. But QEMU Monitor is out of QtEmu! Is there any way to install QEMU Monitor on Windows, with QtEmu?

Please help me!

    QEMU can be started with option "-monitor" so you can send commands to it there. I never used QtEmu so not sure how it starts QEMU. If you figure out how, check out https://qemu.weilnetz.de/w64/2012/2012-08-24/qemu-doc.html#pcsys_005fmonitor.

    So basically, you can use "change" command to mount and unmount a CD drive or other storage devices. For example, "change ide1-cd0 /tmp/file.iso" to mount an image file. The device names are not fixed across different VM configurations. "info block" can tell you what name you need to use.

    sorry i just discovered QEMU, it’s far now, but it can help people in the future.

    I dislike QTEmu and others IHM, too much bugs currently (2022)..

    With QEMU

    • default mode: you can directly have an access with the window, go to view and you can switch by clicking on "compat monitor 0" . You can also detach the monitor.
    • sdl: ctrl+alt 2.

    Here:

    • Identify your devices by "info block"

    enter image description here

    As you can see here, i ran without anything (it’s just to show).

    To change/add content of your cd-rom, "Change "

    • here my device is "ide1-cd0"
    • Path can be your physical or virtual drive, a disk image, you can always swap according your needs.

    As you can see now, i use "R:", a virtual device from a software like daemon tools (an alt).

    enter image description here

    I think it’s better, before to swap, to eject from the guest… But perhaps
    it depends of your OS. For the while i used it, the most of time, with win98x.
