I found a couple other posts that touched on the topic but wanted to get some more input. I have both Windows Home Server and Server 2008 ready to install for a home file (and possible web, at some point) server that I am still gathering parts for. I want to get familiar with Server 2008 but use the features of WHS, mainly Drive Extender. My question: would running WHS as a VM with Hyper-V inside Server 2008 cut out/disable any important features that WHS offers? Any disadvantages/problems that I would run into?
