You can set up your lan DNS/DHCP to use the same IP for both. And the virtualized instances are nice because they're scalable. If you're using virtual disks for storage, they only use up however much storage they are actually using on your drive and are hard limited by a software value. It also lets you upgrade the server later super easily by just changing values in the VM settings.

I do most of my stuff on HyperV or Virtual box. The VHD storage is also nice because it is agnostic and can be read by any system cabaple of running virtual box.
