Hello,
It turns out I forgot to blank the pins on my card so while my server worked fine on a physical install, VMWare wouldn't pass the card through properly. I blanked the pins and now it boots normally
I am using fresh drives and I have decided to keep my prod drives on DSM 5 for now. We will see how stable DSM 6 is with the new loader but I wouldn't move your data just yet is there is still some small issues that need to be worked out
Big thanks to Jun, Trantor, Quicknick and all the other fantastic devs that made this possible!
