Qemu 突然找不到虚拟鼠标和键盘的任何总线: -device usb-tablet: No 'usb-bus' bus found for device 'usb-tablet'

Qemu 突然找不到虚拟鼠标和键盘的任何总线: -device usb-tablet: No 'usb-bus' bus found for device 'usb-tablet'

我前段时间在 Qemu/KVM 中安装了 macOS Catalina,几个月来它运行良好,直到今天我需要一些东西并想要启动虚拟机时。弹出这个错误:

Error starting domain: internal error: qemu unexpectedly closed the monitor: 2022-01-11T10:16:53.873634Z qemu-system-x86_64: -device usb-tablet: No 'usb-bus' bus found for device 'usb-tablet'

我可以看到,usb-tablet但我不知道它的目的是什么,而且由于我无论如何都不是 Qemu 的专家,所以我想在这里询问它,因为我没有找到有关此特定错误的任何信息全部。

编辑

从我所能找到的情况来看,我确实发现qemu实际上是在抱怨找不到鼠标和键盘的总线。我已经删除了线条,首先是鼠标的线条。然后键盘和虚拟机启动时不会像以前一样出现任何问题,但当然,正如您可能已经猜到的那样,我没有任何键盘和鼠标可以在虚拟机中工作。 老鼠 键盘

我的问题是如何解决这个问题?我尝试过一种方法,但不起作用。

我只在 macOS 虚拟机上遇到此错误,我的其他 12 个虚拟机(Windows 和 Linux)都运行良好。

我在另一台设备上还有两个虚拟机:Catalina 和 HighSierra。我在那里得到了完全相同的错误。

答案1

我在搜索时自己找到了真正的解决方案。

首先,我想我必须提到这是我正在使用的项目:来自 Kholia 的 OSX-KVM

在寻找解决问题的过程中,我OpenCore-Boot.sh首先查看了用于启动机器的原始文件,-usb这里有这个选项。

-usb -device usb-kbd -device usb-tablet
^   ^ 

我现在在virt-manager文件中不知何故丢失了选项,我不知道这是怎么发生的,因为我从来没有玩过这些线。

使固定

所以我只需要在该qemu args部分中添加它,如下所示:

    <qemu:arg value="-usb"/>
    <qemu:arg value="-device"/>
    <qemu:arg value="usb-tablet"/>
    <qemu:arg value="-device"/>
    <qemu:arg value="usb-kbd"/>

享受!
