Weihang,

Basically what you want to do is select bridging in your vBox settings for
your VM. Then select your real system's ethernet adapter, expand the little
drop down below that and it will allow you to choose which vNIC you want. I
choose the Intel 82545EM device which gives me an em0 vNIC. in my FreeBSD VM
I have the following three lines pertaining to setting up my network

sshd_enable="YES"
ifconfig_em0="inet 192.168.0.20 netmask 255.255.255.0"
defaultrouter="192.168.0.1"
hostname="freebsd-bsd.xaerolimit.net"

and of course, that hostname does resolve on my lan, but that's not what
this e-mail is about. Hope this helps.
