When installing Windows 8 Consumer Preview within VirtualBox, you cannot got on further from the goldfish screen. Or, you cannot go on further from the new BSOD screen.
This error occurs when your host OS’s system doesn’t have the VT-x/AMD-V acceleration.
[showpic src=”win8cp/“]The error dialog that the VirtualBox spits out when the guest operating system requires the VT-x/AMD-V acceleration but the host OS does not have it.
Also, when you ignore the VirtualBox error dialog about the virtualization needs, you’ll get the goldfish screen and stop or get the new BSOD screen. This goldfish screen is the Windows 8 Consumer Preview edition’s startup logo.

How to workaround this error.
To get the system to workaround this error, you’ll need to enable this in the BIOS. But you’ll need a virtualization capable system.
- Use a system with VT-x/AMD-V (Virtualization) technology capable system.
- If you know that your system has this virtualization accerlation technology but get this error, you will need to enable this in the BIOS.
- Enable below in the BIOS. It depends on the system vendor for what each vendor calls the virtualization technology, but it will generally say virtualization something.
- Intel(R) Virtualization Technology: Enabled
- Intel(R) VT-d Feature: Enabled
- VT-d: Enabled
- Intel(R) VT for Directed I/O: Enabled
- Look into the Intel website for further details (English): http://www.intel.com/support/motherboards/server/sb/CS-031147.htm
If you have done above and you still get an error with a 64 bit system with HP BIOS (the above examples uses 32bit system for host and guest), it might be due to a bug in the BIOS.
Try looking into the following thread, x64 Guest will not run on Windows 7 x64 = HP BIOS bug from VirtualBox.
