@gb.123 Interesting -- alert the XCP-ng team to take a closer look, if they haven't seen this already.

RE: GPU Passthrough
@gb.123 I'm sure you can also find some NVIDIA "hoe to" guides that might be helpful. As mentioned before, I've only done server passthrough so that all VMs would get access,
so sorry I can't provide more specifics. You can always try with one or the other option and add the other if it still doesn't work. I'm pretty sure, though, that you do need both enabled.
Keep us posted! -
RE: GPU Passthrough
@gb.123 Are you sure you have the correct drivers installed? Also, check if the GPU is compatible with AMD CPUs -- I only had Intel CPUs, so am not sure if that's an issue or not.

RE: GPU Passthrough
@gb.123 You need to do both. After adding the PCI device, you might also need to specifically enable "passthrough" for that device within the VM's settings. It may do it automatically when you add it.
Make sure the appropriate NVIDIA driver is also installed on the the VM. -
RE: GPU Passthrough
@gb.123 YOu are trying to do passthrough to a specific VM? I don't think that used to be supported, but maybe is now.
Are NVIDIA drivers installed on the VM, as needed?
Sorry, it's been a while since doing this so I'm digging back into my memory.
Also, is IOMMU supported and enabled in the BIOS?
Also, check this out and see if it may be of some help:

RE: GPU Passthrough
@gb.123 Ah, OK. then the more powerful GP is the RTX4060, right? If so, use it for the passthrough. Also, on some CPUs you have to do a BIOS setting to allow this to work, because of memory limitations, but only on probably much older systems, if I recall correctly.

RE: GPU Passthrough
@gb.123 You need one video card for your administrative console and another can be used for GPU passthrough. There must be two separate physical devices.
So make sure you have two video boards, one that has the GPU capabilities you want to use in your passthrough configuration.
