Hello!

I have AsRock Taichy X399 with CPU Threadripper 1900X and four GPUs Sapphire Radeon RX Vega 64 Liquid. I installed XCP-NG and enabled in BIOS SVM-mode and SR-IOU mode.
After install Windows 10 like a virtual machine, I see only three cards.

Is problem in the motherboard?
Should I update the BIOS?

Thank you for advices.

Are you sure one of the GPU is not reserved for the hypervisor or another VM?

I'm also curious if you used IOMMU and how did you manage the groupings.

Oh, how many M.2 SSD are you using?

P.S. BIOS update is higly recommended, with a good CMOS clear afterwards.
