鼠标和键盘不能在beemboard的qemu仿真中使用最新的angstrom图像

Question

我试图在我的Ubuntu 12.04笔记本电脑上为qemu中的beaglexm模拟一个埃图像。在新窗口中，映像启动并自动登录到GNOME shell。但键盘和鼠标仍然没有反应。

我给出了以下命令：

qemu-system-arm -M beaglexm -m 1024 -sd Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img -clock unix -serial stdio -device usb-mouse -device usb-kbd -net nic -net user,hostfwd=::2222-:22

随着仿真的开始，在父终端上生成以下日志

图像完全启动到shell后，按键没有响应但在父终端中记录以下内容：

usb-kbd: warning: key event queue full

我通过从头开始构建最新的linaro-qemu尝试了here给出的解决方案，但结果相同。

此外，我无法进入此运行图像。我发出了以下命令

ssh -p 2222 root@localhost

它只是拒绝连接

键盘和鼠标无响应的原因是，您需要指定主机的USB总线编号以及USB Pass-Through的设备编号。

$ lsusb

我的键盘总线编号为002，地址为001.因此，请根据您的设备编号和地址更改命令。

假设键盘编号和地址相同，您的命令如下：

qemu-system-arm -M beaglexm -m 1024 -sd Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img -clock unix -serial stdio -serial stdio -usb -device usb-host,hostbus=2,hostaddr=1

以与键盘相同的方式添加鼠标。如果没有光标指针，您可以将-show-cursor添加到命令中。
