Prox9.1.1 PCI passthrough not working properly.

[marshe]

running into a issue using an older DELL PowerEdge R730XD running dual Intel(R) Xeon(R) CPU E5-2680 v3, a PNY RTX 2080, 128gb ecc ram, and an Intel x710 quad nic. I am running Prox VE 9.1.1, but my windows vm's cant install drivers to the RTX card, giving an error (code 43).
The windows VM is unable to properly install the card. Giving the error (code 43).

tried changing machine: vIOMMU from = intel to default. nothing changed about the error code in the windows VM. also tried machine: vIOMMU = VirtIO and nothing changed there either.

That is to be expected as a virtual IOMMU inside the VM is unrelated to PCI(e) passthrough to the VM.

Looks like you used an out of date guide for configuring the passthrough (instead of the Proxmox manual) but it could also be because of this particular GPU (as not every device resets properly, make sure not to book using that GPU) or the NVidia driver itself. NVidia used to cause error 43 on purpose in the past, so I have no experience with their GPUs, sorry.

Its the same issue with a couple other windows VM's. I have 4 GPU's in the system. RTX2080 + TeslaP4 + RadeonProWX7100 + RadeonProWX3100. all with the exact same issues where the windows OS sees them, but cant utilize them. I have dummy monitor dongles in the 2080, 7100, and 3100. (P4 doesn't have video outputs, trying to use as a decoder/encoder for video feeds.)
