Hello,
Im new in proxmox so please be indulgent. I have installed proxmox with my stup :
X399 Aorus gaming 7
RAM 40 Go
GPU P5000 Nvidia 16 GO Slot 16x PCI 3.0

I make split GPU and its work on VM
4 Go for 4 VM

so I put a second GPU on the second slot 16x PCI 3.0 but i have this error :
nvidia-smi
Unable to determine the device handle for GPU 0000:07:00.0: GPU is lost. Reboot the system to recover this GPU

dmesg | grep GPU

but I see the 2 GPUs :

lspci | grep -i nvidia
07:00.0 VGA compatible controller: NVIDIA Corporation GP104GL [Quadro P5000] (rev a1)
07:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1)
41:00.0 VGA compatible controller: NVIDIA Corporation GP104GL [Quadro P5000] (rev a1)
41:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1)


I tested to change slot on PCI 4x and its work but i want it work on PCie x16 for having good rendering
