Your "parent partition" (the first copy of Win2k8 you installed) *is* running on the hypervisor. I will send you some slides offlist that explain what is happening from an architectural perspective. The hypervisor now arbitrates all access to CPU (for example), however access to physical resources (e.g. disk, network) are handled by drivers in the parent partition. Guest machines use VMBus to send data to the parent partition (e.g. via shared memory space or CPU cache) which then sends it to physical resources.
The problem with the "stand alone" Hyper-V is no clustering feature support. That means you don't get any HA features. As you surmise, you probably can't use the host for very much except being a host. But that's probably what you want to do anyway (gives you more resources for the guests), and if you buy an Enterprise license you get 1 physical license, and 4 guest licenses, so you aren't "wasting" anything per se - you can't convert the physical licence into an extra virtual one to run an additional workload.

I understand the reason for that now. The question boils down to, wouldn't I want all instances of servers on a hardware platform to be running on the "bare metal" hypervisor if possible? One of the goals of virtualizing is easy portability to run on alternate/standby hardware, and the 2008 Hyper-V host server isn't portable. That means not using the host server for anything but a host server, and that's a waste of a license. Am I missing anything? Why would I NOT prefer to use standalone Hyper-V for all virtualized servers including 2008?
