System environment Background: Lenovo IDEAPAD510;64BIT/64-bit system.
Oracle virtual box:version 5.1.2 r108956;
UNIX ISO Download:
Previously installed the wrong ISO, has been error-like: This kernel requires a x86-64 cpu,but only detected an i686 CPU.
So go to the FreeBSD official website installer images-> i386 to find the corresponding ISO.
Index is:
/i386/i386/iso-images/11.1/
The ISO name was downloaded:
Freebsd-11.1-release-i386-bootonly.iso
Link:https://download.freebsd.org/ftp/releases/i386/i386/iso-images/11.1/
You can download the corresponding ISO according to your computer CPU.

P.S. AMD64 does not work with my computer CPU I guess. and i386 and so-called i686 are more similar. The installation was successful. It's a dog poop.
