# NVIDIA vGPU on PVE 7.1 with a NVIDIA T1000 GPU

# NVIDIA vGPU with the GRID 15.0 driver on Proxmox
|
||||
|
||||
This tutorial (and included patches) should allow you to use vGPU unlock on PVE 7.1 with the opt-in 5.15 Linux Kernel with a NVIDIA T1000 GPU. The GPU uses the TU117 Chip so other GPUs with the same Chip (T400, T600, GTX 1650 **NOT** Super) will probably work (no guarantees).
|
||||
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.
|
||||
|
||||
### This tutorial assumes you are using a clean install of PVE 7.1, or ymmv when using an existing installation. Make sure to always have backups!

|
||||
|

This guide should work for other linux systems with a recent kernel (5.15 to 5.19) but I have only tested it on the current proxmox version.
|
||||
If you are not using proxmox, you have to adapt some parts of this tutorial to work for your distribution.

PVE 7.1 comes with version 5.13 of the Linux Kernel, that version is incompatible with vGPU. For this guide you will have to install version 5.15, which will probably come with PVE 7.2 (~Q2 2022) but is opt-in on current PVE versions

## Enabling IOMMU
|
||||
#### Note: Usually this isn't required for vGPU to work, but it doesn't hurt to enable it. You can skip this section, but if you run into problems later on, make sure to enable IOMMU.
|
||||
|
||||
Assuming you installed PVE with ZFS-on-root and efi, you are booting with systemd-boot. All other installations use grub. The following instructions *ONLY* apply to systemd-boot, grub is different.
|
||||
To enable IOMMU you have to enable it in your BIOS/UEFI first. Due to it being vendor specific, I am unable to provide instructions for that, but usually for Intel systems the option you are looking for is called something like "Vt-d", AMD systems tend to call it "IOMMU".
|
||||
|
||||
To enable IOMMU you have to enable it in your UEFI first. Due to it being vendor specific, I am unable to provide instructions for that, but usually for Intel systems the option you are looking for is called something like "Vt-d", AMD systems tend to call it "IOMMU".
|
||||
After enabling it in your BIOS/UEFI, you also have to enable it in your kernel. Depending on how your system is booting, there are two ways to do that.
|
||||
|
||||
After enabling IOMMU in your UEFI, you have to add some options to your kernel to enable it in proxmox. Edit the kernel command line like this
|
||||
```bash
|
||||
nano /etc/kernel/cmdline
|
||||
```
|
||||
If you installed your system with ZFS-on-root and in UEFI mode, then you are using systemd-boot, everything else is GRUB. GRUB is way more common so if you are unsure, you are probably using that.
|
||||
|
||||
On a clean installation the file might look similar to this:
|
||||
```
|
||||
root=ZFS=rpool/ROOT/pve-1 boot=zfs
|
||||
```
|
||||
Depending on which system you are using to boot, you have to chose from the following two options:
|
||||
|
||||
On Intel systems, append this line at the end
|
||||
```
|
||||
intel_iommu=on iommu=pt
|
||||
```
|
||||
<details>
|
||||
<summary>GRUB</summary>
|
||||
|
||||
For AMD, use this
|
||||
```
|
||||
amd_iommu=on iommu=pt
|
||||
```
|
||||
Open the file `/etc/default/grub` in your favorite editor
|
||||
```bash
|
||||
nano /etc/default/grub
|
||||
```
|
||||
|
||||
After editing the file, it should look similar to this
|
||||
```
|
||||
root=ZFS=rpool/ROOT/pve-1 boot=zfs intel_iommu=on iommu=pt
|
||||
```
|
||||
The kernel parameters have to be appended to the variable `GRUB_CMDLINE_LINUX_DEFAULT`. On a clean installation that line should look like this
|
||||
```
|
||||
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
|
||||
```
|
||||
|
||||
Save and exit using Ctrl+O and then Ctrl+X
|
||||
If you are using an Intel system, append this after `quiet`:
|
||||
```
|
||||
intel_iommu=on iommu=pt
|
||||
```
|
||||
|
||||
On AMD systems, append this after `quiet`:
|
||||
```
|
||||
amd_iommu=on iommu=pt
|
||||
```
|
||||
|
||||
The result should look like this (for intel systems):
|
||||
```
|
||||
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
|
||||
```
|
||||
|
||||
Now, save and exit from the editor using Ctrl+O and then Ctrl+X and then apply your changes:

</details>

|
||||
<summary>systemd-boot</summary>

## NVIDIA Driver
|
||||
|
||||
### Choosing the right driver version
|
||||
|
||||
This is the tricky part, at the time of writing (Jan 2022), there are [three active branches](https://docs.nvidia.com/grid/) of the NVIDIA vGPU driver. The latest is branch 13 (long term support branch until mid 2024) with driver version 470. I had no luck getting *any* version of that driver to work with vGPU at all but as always - ymmv.
|
||||
|
||||
Branch 12 is a "regular" production branch with support until January of 2022 and has driver version number 460. Lots of people are running that driver in combination with the Linux Kernel 5.15. I got it installed with my gpu, but as soon as I tried to use the gpu in my VM, the display would freeze every 30-ish seconds and `nvidia-vgpu-mgr.service` would report an error similar to `error: vmiop_log: (0x0): XID 43 detected on physical_chid:0x1c, guest_chid:0x14`. At first I thought I messed up some of the driver patches required to get the driver working on kernels newer than 5.11 - so I tried on PVE 6.4 without any patches (5.4 kernel) but got the same errors there. If anyone knows what's causing this error, or even how to fix it, **please** let me know :)
|
||||
|
||||
Ruling out those two branches only leaves the older long term support branch 11: It is supported until mid 2023 and has the driver version 450. Like the other branch (12), you have to patch some parts of the driver to get it working on the Linux Kernel 5.15. I tried every patch I could find on the Internet (mostly twelve.patch and fourteen.patch and their variations) but no combination of them allowed me to install the driver - the installer would always complain about my system being incompatible. So I spent a few hours looking at the existing patches and reviewing the files they patch to finally come up with my own patch: Basically, it adapts twelve.patch and fourteen.patch to this older driver (they seem to be designed for the branch 12 driver) and merges them into a single patch.
|
||||
As of the time of this writing (December 2022), the latest available GRID driver is 15.0 with vGPU driver version 525.60.12. 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
|
||||
|
||||
I will be using the latest driver from branch 11 (at the time of writing that would be 11.6 / 450.156).
|
||||
|
||||
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.
|
||||
|
||||
After downloading version 11.6 you should have a zip file called `NVIDIA-GRID-Linux-KVM-450.156-450.156.00-453.23.zip`, extract that and copy the file `NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run` to your PVE host into the `/root/` folder
|
||||
```bash
|
||||
scp NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run root@pve:/root/
|
||||
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.
|
||||
|
||||
The file you are looking for is called `NVIDIA-GRID-Linux-KVM-525.60.12-525.60.13-527.41.zip`, you can get it from the download portal by downloading version 15.0 for `Linux KVM`.
|
||||
|
||||
|
||||
|
||||
For those who want to find the file somewhere else, here are some checksums :)
|
||||
```

||||

|
||||
md5: 0e2be7de643b99a62a1cca6ca37fd1ee
|
||||
```
|
||||
|
||||
After downloading, extract that and copy the file `NVIDIA-Linux-x86_64-525.60.12-vgpu-kvm.run` to your Proxmox host into the `/root/` folder
|
||||
```bash
|
||||

||||
> Now, skip the following two sections and continue at [Finishing touches](#finishing-touches)
|
||||
|
||||
### Patching the driver
|
||||
|
||||
Now, on the proxmox host, make the driver executable
|
||||
```bash
|
||||
chmod +x NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run
|
||||
chmod +x NVIDIA-Linux-x86_64-525.60.12-vgpu-kvm.run
|
||||
```
|
||||
|
||||
And then unpack it
|
||||
And then patch it
|
||||
```bash
|
||||
./NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run -x
|
||||
./NVIDIA-Linux-x86_64-525.60.12-vgpu-kvm.run --apply-patch ~/vgpu-proxmox/525.60.12.patch
|
||||
```
|
||||
That should output a lot of lines ending with
|
||||
```
|
||||
Self-extractible archive "NVIDIA-Linux-x86_64-525.60.12-vgpu-kvm-custom.run" successfully created.
|
||||
```
|
||||
|
||||
Go inside the extracted folder
|
||||
```bash
|
||||
cd NVIDIA-Linux-x86_64-450.156-vgpu-kvm/
|
||||
```
|
||||
|
||||
To be able to install the driver on your proxmox host, apply the driver patch
|
||||
```bash
|
||||
patch -p0 < ~/vgpu-5.15/450_5.15.patch
|
||||
```
|
||||
|
||||
If everything went right (and you are using the exact same nvidia driver version 11.6), the output should be exactly this
|
||||
```

I've included an adapted version of the `nvidia-smi` [wrapper script](https://github.com/erin-allison/nvidia-merged-arch/blob/d2ce752cd38461b53b7e017612410a3348aa86e5/nvidia-smi) to get useful output from `nvidia-smi vgpu`.

Without that wrapper script, running `nvidia-smi vgpu` in your shell results in this output
|
||||
```

## vGPU overrides
|
||||
|
||||
Further up we have created the file `/etc/vgpu_unlock/profile_override.toml` and I didn't explain what it was for yet. Using that file you can override lots of parameters for your vGPU instances: For example you can change the maximum resolution, enable/disable the frame rate limiter, enable/disable support for CUDA or change the vram size of your virtual gpus.
|
||||
|
||||
If we take a look at the output of `mdevctl types` we see lots of different types that we can choose from. However, if we for example chose `GRID RTX6000-4Q` which gives us 4GB of vram in a VM, we are locked to that type for all of our VMs. Meaning we can only have 4GB VMs, its not possible to mix different types to have one 4GB VM, and two 2GB VMs.
|
||||
|
||||
> ### Important notes
|
||||
>
|
||||
> Q profiles *can* give you horrible performance in OpenGL applications/games. To fix that, switch to an equivalent A or B profile (for example `GRID RTX6000-4B`)
|
||||
>
|
||||
> C profiles (for example `GRID RTX6000-4C`) only work on Linux, don't try using those on Windows, it will not work - at all.
|
||||
>
|
||||
> A profiles (for example `GRID RTX6000-4A`) will NOT work on Linux, they only work on Windows.
|
||||
|
||||
All of that changes with the override config file. Technically we are still locked to only using one profile, but now its possible to change the vram of the profile on a VM basis so even though we have three `GRID RTX6000-4Q` instances, one VM can have 4GB or vram but we can override the vram size for the other two VMs to only 2GB.
|
||||
|
||||
Lets take a look at this example config override file (its in TOML format)
|
||||
```toml
|
||||
[profile.nvidia-259]
|
||||
num_displays = 1 # Max number of virtual displays. Usually 1 if you want a simple remote gaming VM
|
||||
display_width = 1920 # Maximum display width in the VM
|
||||
display_height = 1080 # Maximum display height in the VM
|
||||
max_pixels = 2073600 # This is the product of display_width and display_height so 1920 * 1080 = 2073600
|
||||
cuda_enabled = 1 # Enables CUDA support. Either 1 or 0 for enabled/disabled
|
||||
frl_enabled = 1 # This controls the frame rate limiter, if you enable it your fps in the VM get locked to 60fps. Either 1 or 0 for enabled/disabled
|
||||
framebuffer = 0x74000000
|
||||
framebuffer_reservation = 0xC000000 # In combination with the framebuffer size
|
||||
# above, these two lines will give you a VM
|
||||
# with 2GB of VRAM (framebuffer + framebuffer_reservation = VRAM size in bytes).
|
||||
# See below for some other sizes
|
||||
|
||||
[vm.100]
|
||||
frl_enabled = 0
|
||||
# You can override all the options from above here too. If you want to add more overrides for a new VM, just copy this block and change the VM ID
|
||||
```
|
||||
|
||||
There are two blocks here, the first being `[profile.nvidia-259]` and the second `[vm.100]`.
|
||||
The first one applies the overrides to all VM instances of the `nvidia-259` type (thats `GRID RTX6000-4Q`) and the second one applies its overrides only to one specific VM, that one with the proxmox VM ID `100`.
|
||||
|
||||
The proxmox VM ID is the same number that you see in the proxmox webinterface, next to the VM name.
|
||||
|
||||
You don't have to specify all parameters, only the ones you need/want. There are some more that I didn't mention here, you can find them by going through the source code of the `vgpu_unlock-rs` repo.
|
||||
|
||||
For a simple 1080p remote gaming VM I recommend going with something like this
|
||||
```toml
|
||||
[profile.nvidia-259] # choose the profile you want here
|
||||
num_displays = 1
|
||||
display_width = 1920
|
||||
display_height = 1080
|
||||
max_pixels = 2073600
|
||||
```
|
||||
|
||||
### Common VRAM sizes
|
||||
|
||||
Here are some common framebuffer sizes that you might want to use:
|
||||
|
||||

|
||||
```toml
|
||||
framebuffer = 0x1A000000
|
||||
framebuffer_reservation = 0x6000000

||||
```

```toml
|
||||
framebuffer = 0x74000000
|
||||
framebuffer_reservation = 0xC000000
|
||||
```
|
||||
- 3GB:
|
||||
```toml
|
||||
framebuffer = 0xB0000000
|
||||
framebuffer_reservation = 0x10000000
|
||||
```
|
||||
- 4GB:
|
||||
```toml
|
||||
framebuffer = 0xEC000000
|
||||
framebuffer_reservation = 0x14000000
|
||||
```
|
||||
- 5GB:
|
||||
```toml
|
||||
framebuffer = 0x128000000
|
||||
framebuffer_reservation = 0x18000000

||||
```
|
||||

||||
framebuffer = 0x164000000
|
||||
framebuffer_reservation = 0x1C000000
|
||||
```
|
||||
- 8GB:
|
||||
```toml
|
||||
framebuffer = 0x1DC000000
|
||||
framebuffer_reservation = 0x24000000
|
||||
```
|
||||
- 10GB:
|
||||
```toml
|
||||
framebuffer = 0x254000000
|
||||
framebuffer_reservation = 0x2C000000
|
||||
```
|
||||
- 12GB:
|
||||
```toml
|
||||
framebuffer = 0x2CC000000
|
||||
framebuffer_reservation = 0x34000000
|
||||
```
|
||||
- 16GB:
|
||||
```toml
|
||||
framebuffer = 0x3BC000000
|
||||
framebuffer_reservation = 0x44000000
|
||||
```
|
||||
- 20GB:
|
||||
```toml
|
||||
framebuffer = 0x4AC000000
|
||||
framebuffer_reservation = 0x54000000
|
||||
```
|
||||
- 24GB:
|
||||
```toml
|
||||
framebuffer = 0x59C000000
|
||||
framebuffer_reservation = 0x64000000
|
||||
```
|
||||
- 32GB:
|
||||
```toml
|
||||
framebuffer = 0x77C000000
|
||||
framebuffer_reservation = 0x84000000
|
||||
```
|
||||
- 48GB:
|
||||
```toml
|
||||
framebuffer = 0xB2D200000
|
||||
framebuffer_reservation = 0xD2E00000
|
||||
```
|
||||
|
||||
`framebuffer` and `framebuffer_reservation` will always equal the VRAM size in bytes when added together.
|
||||
|
||||
### Spoofing your vGPU instance
|
||||
|
||||
#### Note: This only works on Windows guests, don't bother trying on Linux.
|
||||
|
||||
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.
|
||||
|
||||
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:
|
||||
```toml
|
||||
[profile.nvidia-259]
|
||||
# insert all of your other overrides here too
|
||||
pci_device_id = 0x1E30
|
||||
pci_id = 0x1E3012BA
|
||||
```
|
||||
|
||||
`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`.
|
||||
|
||||
`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 must use `0000` as the second value for `pci_id`. 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
|
||||
|
||||
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`.
|
||||
|
||||
Finish by clicking `Add`, start the VM and install the required drivers. After installing the drivers you can shut the VM down and remove the virtual display adapter by selecting `Display` in the `Hardware` section and selecting `none (none)`. ONLY do that if you have some other way to access the Virtual Machine like Parsec or Remote Desktop because the Proxmox Console won't work anymore.
|
||||
|
||||
Enjoy your new vGPU VM :)
|
||||
|
||||
## 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`
