I am trying to build a windows 7 guest using virtualbox-ose-3.1.8. When
starting the virtual machine to install the OS, I get the warning:

Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of
your host computer."
I have enabled the following in the BIOS:
Intel(R) Virtualization Technology
Intel(R) VT-d Feature
I have not created a KVM module in the kernel (using
gentoo-sources-2.6.34-r12). Is this needed?
No, but now that you've mentioned it have you tried qemu-kvm to see if
it has the same complaint?
VBox is a fork of qemu, but AFAIK it doesn't use hardware virtualization
the way qemu-kvm does (and even qemu added kvm support a few months ago).
All three products are good enough to seem like black magic to me
