如何修复该问题？
最佳方法
这是 VirtualBox 在运行时被 Ubuntu 升级后的典型行为。
解决方案：
-
停止 VirtualBox
-
在https://www.virtualbox.org/wiki/Downloads下载最新的扩展包(所有平台都一样)
-
安装扩展
-
重启 Ubuntu
它现在应该可以与任何以前可以运行的 VM 一起工作。
实际上，日志中包含这个提示：If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs。
次佳方法
如果您需要运行此功能但没有互联网，您可以删除扩展包：
FIle->Preferences->Extensions
并在要启动的机器上将 USB 控制器设置为 1.1。选择它，然后：
Machine->Settings->USB->Set it to 1.1 (or disable it)
这应该可以让你启动。你将无法使用扩展，但它可能会帮助你直到你上网。当你上网时，请按照 Nicolas Raoul’ answer
