Can I use Nvidia GPU from virtual machine?

I will get a Windows machine soon. This machine has a Nvidia GPU Ideally. If I install Ubuntu in a Virtualbox (or other virtualization method), will I be able to access and use this GPU for CUDA programming?

EDIT: I have been provided a link where it says I couldn't. :(

I found another link where it says I could

So in the end, I would welcome answers from people who have tried it (and hopefully succeed :) )
