10GBE Nic Passthrough to OSX VM Doesnt Work, Windows10 VM Works??

Hello Everyone,

 

Im trying to pass-through a Sonnet 10GBE nic to the 2nd vm (OSX) i have on the server. The device is RESETABLE, and i have it Stubed-OUT in the unraid flash config file.

 

My windows 10 vm boots up just fine with it and i got the driver installed and it works. however i can't get it to work from OSX. It keeps saying i need to include a rom file. But its not a GPU why would it want a rom file. Any thoughts?

Server Error:

VM XML OSX That Fails: Exact same code is in Windows 10 XML and it works.
