Ok, I know that my question might be a little misleading as I'm really not suggesting I install Exchange 2010 utilizing DAG in my Hyper-V failover cluster. What I would be doing is installing a VM of Exchange on each server (that happens to be in my Hyper-V cluster) outside of the failover clustering services HA. I have read that this scenario is supported by Microsoft, but was just wondering if anyone had done it and had any real life information to share.
