Installed Virtualbox and the extension pack on windows 7 64 bit OS. It took no more than five minutes. Now to figure out what vm appliances to start with.
Here is the link I referenced: http://www.virtualbox.org/manual/ch01.html#intro-installing
I will try Mac OS X on Virtualbox at a later time. Right now I will try the "OTN Developer Days" image.
