I'm using VirtualBox 3.0.4 r50677 on a windows Vista x64 machine with 8GB of mem. I set the memory for the VM at 1024MB, created a bridged virtual network adapter, and set the # of processors to 2 (this one is a E8500). It sees them just fine and my proc utilization on the host machine's task manager stays at 98-100%. I just pointed the VM to boot off of notfred's fold.iso I created on his website. (which is really cool that you can create a custom iso on the fly like that!)
It doesn't share processor time with the host machine as transparently as if you were just running the windows SMP client in the background but the computer is still usable. (unlike when I tried the same thing under VMware's free thing)
