Unable to insert the virtual optical disk /opt/VirtualBox/additions/VBoxGuestAdditions.iso into the machine Centos_6.8_x86-64_Local.
在创建虚拟机时，操作系统没有64位选项
Why does virtualbox only have 32-bit option, no 64-bit option on Windows 7?
问题原因由很多，在我的场景里是没有开启虚拟化技术，需要在BIOS中开启 Intel Virtualization Technology 选项。
在启动虚拟机后，立刻显示退出，显示 Aborted 状态
virtualbox.org • View topic - VirtualBox 6.1.10 on macOS Catalina 10.15.5 aborting
环境信息
macOS 10.15.6, VirtualBox 6.1, CentOS Linux release 7.5.1804 (Core)
问题描述
在启动虚拟机后，立刻显示退出，显示 Aborted 状态
问题原因
If the last line of the guest's vbox.log cuts out at "checking audio input permissions", that is a known issue with Mac OS for now.
解决方法
Disable audio in the guest's Audio settings to get the guest to run. I think the devs are working on it or waiting for Apple to fix something
注意，我们没有深入，音频对于我们来说无关紧要，直接关闭即可。如果需要使用音频功能时，我们再研究。
