下了一个5.2.X的VisualBox,但是新建虚拟机的时候在Linux类型下没有CentOS, 看了下官方支持的host OS版本,如下
Linux hosts (32-bit and 64-bit[3]). Among others, this includes:
Ubuntu 14.04 LTS, 16.04 LTS, and 17.04
Debian GNU/Linux 7 ("Wheezy"), 8 ("Jessie") and 9 ("Stretch")
Oracle Enterprise Linux 5, Oracle Linux 6 and 7
Redhat Enterprise Linux 5, 6 and 7
Fedora 25 and 26
Gentoo Linux
openSUSE 13.2
也没有CentOS呢, 大家都是怎么装的???
