-# NVIDIA vGPU with the 510 driver
+# NVIDIA vGPU on Proxmox
 
-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.
+[!["Buy Me A Coffee"](https://www.buymeacoffee.com/assets/img/custom_images/orange_img.png)](https://www.buymeacoffee.com/polloloco)
 
-### This tutorial assumes you are using a clean install of Proxmox 7.1, or ymmv when using an existing installation. Make sure to always have backups!
+This document serves as a guide to install NVIDIA vGPU host drivers on the latest Proxmox VE version, at time of writing this its pve 8.1.
 
-The patch included in this repository should work on other linux systems with kernel versions >= 5.13 but I have only tested it on proxmox.
+You can follow this guide if you have a vGPU supported card from [this list](https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html), or if you are using a consumer GPU from the GeForce series or a non-vGPU qualified Quadro GPU. There are several sections with a title similar to "Have a vGPU supported GPU? Read here" in this document, make sure to read those very carefully as this is where the instructions differ for a vGPU qualified card and a consumer card.
-If you are not using proxmox, you have to adapt some parts of this tutorial to work for your distribution.
+
+## Supported cards
+
+The following consumer/not-vGPU-qualified NVIDIA GPUs can be used with vGPU:
+- Most GPUs from the Maxwell 2.0 generation (GTX 9xx, Quadro Mxxxx, Tesla Mxx) **EXCEPT the GTX 970**
+- All GPUs from the Pascal generation (GTX 10xx, Quadro Pxxxx, Tesla Pxx)
+- All GPUs from the Turing generation (GTX 16xx, RTX 20xx, Txxxx)
+
+If you have GPUs from the Ampere and Ada Lovelace generation, you are out of luck, unless you have a vGPU qualified card from [this list](https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html) like the A5000 or RTX 6000 Ada. If you have one of those cards, please consult the [NVIDIA documentation](https://docs.nvidia.com/grid/15.0/grid-vgpu-user-guide/index.html) for help with setting it up.
+
+> **!!! THIS MEANS THAT YOUR RTX 30XX or 40XX WILL NOT WORK !!!**
+
+This guide and all my tests were done on a RTX 2080 Ti which is based on the Turing architechture.
+
+## Important notes before starting
+- This tutorial assumes you are using a clean install of Proxmox VE 8.1.
+- If you are using Proxmox VE 8.1, you **MUST** use 16.x drivers. Older versions only work with pve 7
+- If you tried GPU-passthrough before, you absolutely **MUST** revert all of the steps you did to set that up.
+- If you only have one GPU in your system with no iGPU, your local monitor will **NOT** give you any output anymore after the system boots up. Use SSH or a serial connection if you want terminal access to your machine.
+- Most of the steps can be applied to other linux distributions, however I'm only covering Proxmox VE here.
+
+> ## Are you upgrading from a previous version of this guide?
+>
+> If you are upgrading from a previous version of this guide, you should uninstall the old driver by running `nvidia-uninstall` first.
+>
+> Then you also have to make sure that you are using the latest version of `vgpu_unlock-rs`, otherwise it won't work with the latest driver.
+>
+> Either delete the folder `/opt/vgpu_unlock-rs` or enter the folder and run `git pull` and then recompile the library again using `cargo build --release`

 ## NVIDIA Driver
 
-As of the time of this writing (March 2022), the latest available GRID driver is 14.0 with vGPU driver version 510.47.03. You can check for the latest version [here](https://docs.nvidia.com/grid/). I cannot guarantee that newer versions would work without additional patches, this tutorial only covers 14.0 (510.47.03).
+This repo contains patches that allow you to use vGPU on not-qualified-vGPU cards (consumer GPUs). Those patches are binary patches, which means that each patch works **ONLY** for a specific driver version.
+
+I've created patches for the following driver versions:
+- 16.2 (535.129.03) - Use this if you are on pve 8.1 (kernel 6.2, 6.5 should work too)
+- 16.1 (535.104.06)
+- 16.0 (535.54.06)
+
+> ### The following versions are EOL, don't use them unless you have a very specific reason!
+> - 15.1 (525.85.07)
+> - 15.0 (525.60.12)
+> - 14.4 (510.108.03)
+> - 14.3 (510.108.03)
+> - 14.2 (510.85.03)
+
+You can choose which of those you want to use, but generally its recommended to use the latest, most up-to-date version (16.2 in this case).
+
+If you have a vGPU qualified GPU, you can use other versions too, because you don't need to patch the driver. However, you still have to make sure they are compatible with your proxmox version and kernel. Also I would not recommend using any older versions unless you have a very specific requirement.
 
 ### 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
+I've created a small video tutorial to find the right driver version on the NVIDIA Enterprise Portal. In the video I'm downloading the 15.0 driver, if you want a different one just replace 15.0 with the version you want:
-```bash
+
-scp NVIDIA-Linux-x86_64-510.47.03-vgpu-kvm.run root@pve:/root/
+![Video Tutorial to find the right driver](downloading_driver.mp4)
-```
+
+After downloading, extract the zip file and then copy the file called `NVIDIA-Linux-x86_64-DRIVERVERSION-vgpu-kvm.run` (where DRIVERVERSION is a string like `535.129.03`) from the `Host_Drivers` folder to your Proxmox host into the `/root/` folder using tools like FileZilla, WinSCP, scp or rsync.
+
+### ⚠️ From here on, I will be using the 16.2 driver, but the steps are the same for other driver versions
+
+For example when I run a command like `chmod +x NVIDIA-Linux-x86_64-535.129.03-vgpu-kvm.run`, you should replace `535.129.03` with the driver version you are using (if you are using a different one). You can get the list of version numbers [here](#nvidia-driver).
+
+Every step where you potentially have to replace the version name will have this warning emoji next to it: ⚠️

-### Spoofing your vGPU instance
+### Common VRAM sizes
 
-You can very easily spoof your virtual GPU to a different card, so that you could install normal quadro drivers instead of the GRID drivers that require licensing.
+Here are some common framebuffer sizes that you might want to use:
 
-For that you just have to add two lines to the override config. In this example I'm spoofing my Turing based card to a normal RTX 6000 Quadro card:

-`pci_device_id` is the pci id from the card you want to spoof to. In my case its `0x1E30` which is the `Quadro RTX 6000/8000`.
+`framebuffer` and `framebuffer_reservation` will always equal the VRAM size in bytes when added together.
-
-`pci_id` can be split in two parts: `0x1E30 12BA`, the first part `0x1E30` has to be the same as `pci_device_id`. The second part is the subdevice id. In my case `12BA` means its a RTX 6000 card and not RTX 8000.
-
-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).
 
 ## 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.
+Go to the proxmox webinterface, go to your VM, then to `Hardware`, then to `Add` and select `PCI Device`.
-
-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`.
 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`.

+## Licensing
+
+Usually a license is required to use vGPU, but luckily the community found several ways around that. Spoofing the vGPU instance to a Quadro GPU used to be very popular, but I don't recommend it anymore. I've also removed the related sections from this guide. If you still want it for whatever reason, you can go back in the commit history to find the instructions on how to use that.
+
+The recommended way to get around the license is to set up your own license server. Follow the instructions [here](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls) (or [here](https://gitea.publichub.eu/oscar.krause/fastapi-dls) if the other link is down).
+
+## 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?
+  - [Learn to read](#your-rtx-30xx-or-40xx-will-not-work-at-this-point-in-time)
+- Make sure that you don't have any dummy plugs connected to the GPU ports, they may cause problems as [reported by a user from the vgpu discord](https://discord.com/channels/829786927829745685/1182258311014400040/1187339682082721822)
+
+## 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`
