QEMU：鼠标和键盘设置问题

Question

我在 QEMU KVM 中运行 Windows 8，有两件事使它不太好用。

首先：鼠标很慢（它滞后于移动）并且我看到的鼠标最多。这意味着每次我移动时，首先我会看到宿主鼠标在移动，然后访客鼠标会慢慢地移到它下面。

第二：键盘不能很好地处理按键。所以假设我按“a”几秒钟。通常我希望每 x 毫秒输入一次。在 QEMU 中，一开始只写一个 a，只有当我释放 key 时，所有其他的都是一次写的。

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？ 也许是一些客座司机？ （不过我只发现安装 Spice 的教程太难了，如果你知道可以理解的请指点一下）

感谢任何有用的建议。

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see this article，它帮助我在几周前解决了一个类似的问题。
