-# NVIDIA vGPU with the 510 driver

-Thanks to the great work of a `LIL'pingu` in the vgpu unlock discord we can finally use the (at the time of writing) latest NVIDIA GRID driver with the version number 510.47.03 with most consumer GPUs. Personally I have tested the T1000, a turing based card but others from the discord server got it working with a pascal based card as well.
+In december 2022, NVIDIA released their latest enterprise GRID driver. I created a patch that allows the use of most consumer GPUs for vGPU. One notable exception from that list is every officially unsupported Ampere GPU and GPUs from the Ada Lovelace generation.

You can check for the latest version [here](https://docs.nvidia.com/grid/). I cannot guarantee that newer versions would work without additional patches, the patch in this guide works **ONLY** on 15.0 (525.60.12).
 
 ### Obtaining the driver
 
 NVIDIA doesn't let you freely download vGPU drivers like they do with GeForce or normal Quadro drivers, instead you have to download them through the [NVIDIA Licensing Portal](https://nvid.nvidia.com/dashboard/) (see: [https://www.nvidia.com/en-us/drivers/vgpu-software-driver/](https://www.nvidia.com/en-us/drivers/vgpu-software-driver/)). You can sign up for a free evaluation to get access to the download page.
 
-The file you are looking for is called `NVIDIA-GRID-Linux-KVM-510.47.03-511.65.zip`, you can get it from the download portal by downloading version 14.0 for `Linux KVM`.
+NB: When applying for an eval license, do NOT use your personal email or other email at a free email provider like gmail.com. You will probably have to go through manual review if you use such emails. I have very good experience using a custom domain for my email address, that way the automatic verification usually lets me in after about five minutes.
 
-After downloading, extract that and copy the file `NVIDIA-Linux-x86_64-510.47.03-vgpu-kvm.run` to your Proxmox host into the `/root/` folder
-```bash
-scp NVIDIA-Linux-x86_64-510.47.03-vgpu-kvm.run root@pve:/root/

 You can get the IDs from [here](https://pci-ids.ucw.cz/read/PC/10de/). Just Ctrl+F and search the card you want to spoof to, then copy the id it shows you on the left and use it for `pci_device_id`.
 
-After doing that, click the same id, it should open a new page where it lists the subsystems. If there are none listed, you can remove the `pci_id` entry from above. But if there are some, you have to select the one you want and use its id as the second value for `pci_id` (see above).

+## Important note when spoofing
+
+You have to pick a Quadro Driver from the same driver branch, so in this case R525. Using newer drivers will **NOT WORK** and maybe even make your VM crash.
+
+If you accidentally installed such a driver, its best to either remove the driver completely using DDU or just install a fresh windows VM.
+
+The quadro driver for R525 branch can be found [here (for 527.27)](https://www.nvidia.com/Download/driverResults.aspx/196728/en-us/).
+
+## Drawbacks to spoofing
+
+- You do not have **ANY** CUDA support
+- It only works for Windows VMs
+- FRL (Framerate limiter) does not work, so no matter what settings you use for `frl_config`, it doesn't apply
 
 ## Adding a vGPU to a Proxmox VM
 
-There is only one thing you have to do from the commandline: Open the VM config file and give the VM a uuid.
-
-For that you need your VM ID, in this example I'm using `1000`.
-
-```bash
-nano /etc/pve/qemu-server/<VM-ID>.conf
-```
-
-So with the VM ID 1000, I have to do this:
-
-```bash
-nano /etc/pve/qemu-server/1000.conf
-```
-
-In that file, you have to add a new line at the end:
-```
-args: -uuid 00000000-0000-0000-0000-00000000XXXX
-```
-
-You have to replace `XXXX` with your VM ID. With my 1000 ID I have to use this line:
-```
-args: -uuid 00000000-0000-0000-0000-000000001000
-```
-
-Save and exit from the editor. Thats all you have to do from the terminal.
-
-Now go to the proxmox webinterface, go to your VM, then to `Hardware`, then to `Add` and select `PCI Device`.
+Go to the proxmox webinterface, go to your VM, then to `Hardware`, then to `Add` and select `PCI Device`.
 You should be able to choose from a list of pci devices. Choose your GPU there, its entry should say `Yes` in the `Mediated Devices` column.
 
 Now you should be able to also select the `MDev Type`. Choose whatever profile you want, if you don't remember which one you want, you can see the list of all available types with `mdevctl types`.

+## Common problems
+
+Most problems can be solved by reading the instructions very carefully. For some very common problems, read here:
+
+- The nvidia driver won't install/load
+  - If you were using gpu passthrough before, revert **ALL** of the steps you did or start with a fresh proxmox installation. If you run `lspci -knnd 10de:` and see `vfio-pci` under `Kernel driver in use:` then you have to fix that
+  - Make sure that you are using a supported kernel version (check `uname -a`)
+- My OpenGL performance is absolute garbage, what can I do?
+  - Read [here](#important-notes)
+- `mdevctl types` doesn't output anything, how to fix it?
+  - Make sure that you don't have unlock disabled if you have a consumer gpu ([more information](#have-a-vgpu-supported-card-read-here))
+- vGPU doesn't work on my RTX 3080! What to do?

+## Support
+
+If something isn't working, please create an issue or join the [Discord server](https://discord.gg/5rQsSV3Byq) and ask for help in the `#proxmox-support` channel so that the community can help you.
+
+> ### DO NOT SEND ME A DM, I'M NOT YOUR PERSONAL SUPPORT
+
+When asking for help, please describe your problem in detail instead of just saying "vgpu doesn't work". Usually a rough overview over your system (gpu, mainboard, proxmox version, kernel version, ...) and full output of `dmesg` and/or `journalctl --no-pager -b 0 -u nvidia-vgpu-mgr.service` (<-- this only after starting the VM that causes trouble) is helpful.
+Please also provide the output of `uname -a` and `cat /proc/cmdline`
