Good news! I was able to successfully Install and run Snow Leopard on Oracle's VirtualBox.
The first thing I did was to create a new machine and make it a Mac OS X Server 64-bit. I set my machine settings just above the minimum recommended for the operating system. The SuperDrive needs to be set as primary master drive or the machine will not find the install disk. I had to make sure the install disk was in the SuperDrive before I ran the machine for the first time, that should go without saying but I forgot the first time.
After the language prompt I opened disk utility and formatted the virtual drive as a Mac OS (Journalled) drive. Once this was complete I continued with the install. Through trial and error I found that the computer needs to be kept from going to sleep during the install, if not, the install will be corrupted.
After the install was complete the system rebooted and took me through the set up for a new machine. The first thing I did was to start Software Update to bring the system current.
Over all it should take less than 30 to 45 minutes, depending on the speed of your machine. The virtual machine works great and I am excited to have that option and to have snow leopard as one of my virtual machines with which to work.
