我在 Windows 10 上创建了一个 VirtualBox VM，其中安装了 Ubuntu 18.04
Operating System: Ubuntu 18.04.5 LTS
Kernel: Linux 5.4.0-42-generic
Architecture: x86-64
我想与其他人共享此虚拟机以进行聚会。我尝试了简单的复制和粘贴以及 OCI 导出。虚拟机正在启动，但许多应用程序会使 UI 崩溃。这导致注销。
当我启动任何应用程序时，屏幕尺寸都会多次改变。菜单消失，用户将被注销。
我该如何在导出之前或导出之后以最少的努力修复此问题。如果不能删除/重新添加用户，那就太好了。
在将此虚拟机移至任何其他电脑之前，它运行良好。

好的，我“修复”了这个问题。它与已激活的Hyper-V功能。打开此功能后离开可以了。理论上 VirtualBox 从版本 6 开始支持 Hyper-V。但看起来它并没有像预期的那样工作。
