We're currently building some Windows 2012 servers where we'll be running many VMs, and we're currently trying to test out SR-IOV since we'll need a lot of data to be transferred.

From reading everywhere, it does appear the large majority of tutorials and documentation ask you edit the registry's IOVEnableOverride in order to force SR-IOV to work properly. I was wondering if any of you had done this, and if experienced any issues with stability or any of that sort. We generally do not like to make registry changes, so we'd like to stray from this option.

We're currently using the latest beta bios from Supermicro, as we're using the X9DR7-LN4F-O motherboard, with the Intel X520-DA2 adapter. We were hoping this combo would allow us to use SR-IOV without the registry change, as Supermicro assured us SR-IOV would be fully available on this motherboard.

Should this change be made, or is there perhaps other motherboards were we'd be able to get this to work without the registry change?

Thanks for your time!
