I have actually done this using VB 4.1.4 r74291 I bridged the network connection as it was easier for me to do so, this meant I did not have to configure any port forwarding as all packets seen by the host were also seen by the VM. There is a very good document describing how to do all of this I have linked it below, I would love to know why you are doing this? I use VM to run 4 different operating systems on one of my machines to test software comptability the machine in question is Win7 64 bit 8gb ram and a dual core 2.8ghz processor and its still slow. Running an AC server was so slow, i would not of used it for any length of time in that mode. You could just partition your machine install the second OS and dual boot, it would be way quicker!
