Qemu 突然找不到虛擬滑鼠和鍵盤的任何匯流排：-device usb-tablet: No ‘usb-bus’ bus found for device ‘usb-tablet’
前段時間我在 Qemu/KVM 中安裝了 macOS Catalina，直到今天我需要一些東西並想要啟動虛擬機時，它都可以正常工作幾個月。彈出此錯誤：
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麼，並且由於我無論如何都不是 Qemu 的專家，所以我想在這裡詢問它，因為我沒有找到有關此特定錯誤的任何資訊全部。編輯
據我所知，我確實發現
qemu實際上抱怨找不到滑鼠和鍵盤的匯流排。我已經刪除了線條，首先是滑鼠。然後對於鍵盤和虛擬機啟動時就像以前一樣沒有問題，但是當然，正如您可能已經猜到的那樣，我沒有任何鍵盤和滑鼠可以在虛擬機中工作。
我的問題是我該如何解決這個問題？我嘗試了一種方法，但它不起作用。
我只在 macOS VM 上遇到此錯誤，我的其他 12 個 VM 執行良好，Windows 和 Linux。
這是虛擬機的 XML：

HighSierra。我在那裡得到完全相同的錯誤。
我自己在搜尋時找到了真正的解決方法。
首先，我想我必須提到這個我正在使用的項目：來自 Kholia 的 OSX-KVM。
在尋找解決問題的同時，我查看了最初
OpenCore-Boot.sh用於引導機器的原始文件，-usb這裡有這個選項。-usb -device usb-kbd -device usb-tablet ^ ^我現在不知何故在
virt-manager文件中失去的選項，我不知道這是怎麼發生的，因為我從來沒有玩過這些線。使固定
所以我只需要在該
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。
