QEMU：鼠标和键盘设置问题

Question

我在 QEMU KVM 中运行 Windows 8，有两件事使它不太可用。

第一：鼠标很慢（它落后于移动）并且我看到的鼠标最多。这意味着每次我移动时，我首先看到主机鼠标移动，然后访客鼠标慢慢地进入它的下面。

第二：键盘不能很好地处理按键。假设我按“a”几秒钟。通常我希望每 x 毫秒输入一次 a。在QEMU中，一开始只写入一个a，只有当我松开按键时，所有其他的a才会立即写入。

我的配置是：

我尝试过所有类型的鼠标：PS/2、触摸板和 USB。

这是一个常见问题吗？有解决办法吗？也许有一些客座司机？（但是我只找到了太难的安装Spice教程，所以如果你知道可以理解的教程，请指点我）

感谢您提供任何有用的建议。

我不认为它与 QEMU 严格相关，因为它可能是 QEMU 和尤其是 Windows 之间的问题。请参阅这篇文章，它帮助我在几周前解决了类似的问题。
