Having recently installed Windows 8 on my laptop to take advantage of the Client Hyper-V, I'm working through the kinks that come with a new OS on my daily driver. Hyper-V leverages the built-in Internet Connection Sharing (ICS) to provide NAT and DHCP for internet access for VM's running on the hypervisor. This isn't quite as intuitive as the network implementations in VMware Workstation or Oracle's VirtualBox, but that's a different discussion.
