Publish the specs and let everyone deal with it themselves. MS only needs to support Hyper-V; that is the product. Anything that runs on it (i.e., Operating system) is just a program. Would we expect MS to support every application that runs on Windows? More laws and rules Blandry??? Comparing cars to SW? Would we expect a software recall? Would we expect a auto manufacturer to support cars for free? Nothing is free. Car prices would just start at about $50,000.
