Hello there, I am planing to install Windows 2008 SP2 (not R2) with Hyper-V with Exchange 2008 SP2 DC and Exchange 2010 SP1. I would like to create a guest OS to separate two server roles. Should I install DC or Exchange 2010 SP1 on the guest machine? Or I had better create two guest machine, one for DC and one for Exchange 2010? Many thanks.

Hi, For the performance of recovery in the future, Microsoft recommends to use at least two machine, one for DC and another for Exchange server. And thank exadmin818 for sharing your answer.
