Good afternoon,
If you have any problem with the internet on Windows 8 Customer preview on VirtualBox, change your Virtual Machine settings as follow:
Network – Attached To – NAT
Network – Advanced – Adapter Type – Intel PRO100/1000 MT Desktop (82540 OEM)
Restart your system and the internet should be working.
Best Regards,
Matheus
