我正在构建一个由 Linux 5.9.18 和 Busybox 组成的系统。
我能够打开外壳。但是，我的键盘不能用。
我将 libvirt 与 Qemu 一起使用。
My kernel config is configured as the following (allnoconfig, and then the settings below):
[*] 64-bit kernel
-> General setup
-> Configure standard kernel features
[*] Enable support for printk
-> General setup
[*] Initial RAM filesystem and RAM disk (initramfs/initrd) support
-> Executable file formats / Emulations
[*] Kernel support for ELF binaries
[*] Kernel support for scripts starting with #!
-> Device Drivers
-> Character devices
[*] Enable TTY
-> Device Drivers
-> Character devices
-> Serial drivers
[*] 8250/16550 and compatible serial support
[*] Console on 8250/16550 and compatible serial port
-> File systems
-> Pseudo filesystems
[*] /proc file system support
[*] sysfs file system support
-> Kernel hacking
-> Compile-time checks and compiler options
[*] Debug filesystem
-> Kernel hacking
[*] Early printk
我像这样编辑了 VM 的 XML 文件：
<device>
...
<input type='evdev'>
<source dev='/dev/input/by-id/usb-Dell_Dell_USB_Keyboard-event-kbd' grab='all' repeat='on'/>
</input>
...
</device>
键盘似乎抓住了虚拟机窗口，但当我按任何键时它不会输入任何内容。不确定问题是什么。任何帮助将不胜感激！
谢谢你！
