You did nothing wrong
Since you're using static memory, then on the VM summary page you should see a grayed out widget for VM memory usage. In Hyper-V 2008 R2 VMs consume all memory you allocate to them, so memory usage from hypervisor level is always 100% (Hyper-V API reports that), while it is different in the Guest OS. Once you start using Dynamic memory, then you will be able to see real memory usage/demand.
Given all that, I assume you see everything Hyper-V 2008 R2 allows you to see. Hope this helps!
