我想在我的 ubuntu 机器上安装 ubuntu 作为虚拟机。主机系统的版本是：Ubuntu 18.04.4 LTS
我要安装的 iso 是：ubuntu-18.04.4-desktop-amd64.iso
因此我下载了 vmplayer 并运行：
sudo bash VMware-Player-15.5.1-15018445.x86_64.bundle
当我vmplayer在终端运行时，我得到
[AppLoader] Use shipped Linux kernel AIO access library.
An up-to-date "libaio" or "libaio1" package from your system is preferred.

我选择“创建新虚拟机”，填写所有内容，选择/home/me/vmware/Ubuntu 64-bit位置。我选择 10GB 磁盘容量和“将虚拟磁盘存储为单个文件”。
终端上还有更多输出：

现在，当我启动机器（“打开电源”）时，窗口关闭并且终端显示（始终从 1 到 5）：
