从今天起，我遇到了一个问题，我的鼠标每分钟会冻结两到三次，持续 2-3 秒。我不确定这是否是巧合，但自从我安装了 VirtualBox 以来，这种情况就开始了。之前我可以通过将鼠标插入另一个 USB 端口来解决这个问题，但现在问题又出现了。每次我的鼠标挂起时，我都会得到一个新的 USB 标识（dmesg）：

答案1
这很可能是为客户操作系统提供主机 USB 端口的 VirtualBox 集成模块无法正常工作。
尝试告诉 VirtualBox 不要管主机的 USB 端口。
答案2
同时，我不认为这是 VirtualBox 的问题。因为今天我切换到 Ubuntu Maverick，问题仍然存在。在我换了另一个鼠标后，问题突然消失了。即使我重新安装 Virtualbox 并运行图像，也不会出现任何鼠标滞后现象。我本来会说这是鼠标问题，但它无法解释为什么浏览器在我执行时会以恒定的间隔冻结（就像鼠标指针一样）qemu-img convert -O raw myfile.vhd myfile.bin。我还没有重新安装 qemu，因为我现在不需要它，所以也许 qemu 仍然对系统做了一些“特殊”的事情。此外，它无法解释为什么旧鼠标可以与我的 Ubuntu 笔记本配合使用。但是好吧，我现在就不谈这个了，因为它现在还可以用。
