Have the same board… Tyan is lying, or at least its not FULLY enabled by default on the S8030. For what is working (sorta, still testing) for me: https://www.reddit.com/r/Proxmox/comments/1nm3mpw/comment/nmt0keo/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
Check out this link for how I got it working… still testing but initial results are promising:
Making some more progress. I had to move the VM out of the qemu/kvm user session to the root qemu/kvm session for more permissions. After doing that, the VM started. I’m working on installing the graphics driver from inside the VM. Pretty excited to see this much progress with the iGPU on Meteor Lake.
Update
More success!!
has anyone tried the B60 yet for this same usecase?
I think the limited availability will make it a little less common at the moment
I can’t imagine it’s much different, it’s literally the same chip, just the B50 is cut down.
At the moment in Europe there is availability of the asrock model but it’s going at 700+ where the B50 is 350-400, so not great value at the moment.
Do you have any details on how you got this working? I’m not using proxmox, just Debian on the host. I have Windows VMs working great, but my Linux VMs don’t have DRI3 available and no acceleration. That is on a basic Debian VM with gnome installed.
I have installed 6.17 kernel on the guest and latest mesa drivers and still no joy. I can’t run sunshine or even vkcube on the on the VF.

Same here though haven’t tried sunshine yet. No vkcube, no glxgears (or only on the qemu gpu), this is on either arch/fedora 43 with 6.17 kernel.
can you post your lspci -vvv from one of you clients?
I tried, no luck so far.
I am unsure if skill issue on my side but I have noticed that for B50 it is necessary to update firmware. I wasn’t able to get my B60 to update its firmware in windows and then dug deeper in to the release notes of the 6979 driver and noticed it only contains updated firmware for B50 and A series.
Thanks for pointing us in this direction, Wendell. I just saw your video and picked up two B50 cards for some testing at work. I’m looking forward to trying this out this week as time permits. We may have loss of use of our facility in about 6 months for a week or two while new generators get installed, and if this is stable enough by then, we might virtualize a bunch of staff’s desktops temporarily. The licensing should be fun to sort out, but much better than alternatives we have investigated in the past (VMWare/Nvidia VDI circa 2019 pricing).
For those having trouble getting the B50 to work on Linux, I’m posting my Proxmox/Arch guide so you can follow my exact steps.
This guide might not be perfectly clear, so please ask questions if you find any errors or confusing parts. The main hurdle, which took me a moment to solve, was the non-existent display output.
The B50 is a pure rendering card, which means you must create a virtual monitor in Linux. This gives the B50 a target to render to, which tools like Sunshine can then capture. In Sway, this is pretty easy to accomplish. However, I’m still having trouble getting this to work reliably in GNOME and KDE at this moment.
This seems to be a Wayland-specific issue. In traditional X11, you can typically just provide an EDID file to create a virtual monitor, but I still need to test that configuration as well.
I’m experimenting with this setup quite a lot in my spare time, so I apologize if the guide isn’t perfectly polished.
Here is the lspci -vvv output from my client, LNX-CLIENT-04, which is running Arch/Sway:

[builder@LNX-CLIENT-04 ~]$
Here are the steps I take to create the virtual machine (and, essentially, play games on it):
### Part 1: VM Creation & "Production" Hardware Swap
1. **Create the VM in Proxmox:**
* **OS:** Select your Arch Linux ISO.
* **System:** `Machine: q35`, `BIOS: OVMF (UEFI)`.
* **Display:** **`VirtIO-GPU`** (This is *only* for the installation).
* **Network:** `VirtIO (paravirtualized)`.
2. **Install Base System:**
* Start the VM and use the Proxmox `Console`.
* Perform your standard Arch install.
* **Critically,** install `openssh` and `nano` and create your user (e.g., `builder`).
* After installation, `chroot` into your new system, set a password for `builder`, and enable the SSH daemon: `systemctl enable sshd.service`.
3. **Shut down the VM.**
4. **Perform the Hardware Swap (In Proxmox):**
* Select your new VM and go to the **Hardware** tab.
* **Remove Display:** Select the `VirtIO-GPU` and click `Remove`.
* **Add Headless Display:** Click `Add` -\> `Display`. Set `Graphic card: None`.
* **Add GPU Passthrough:** Click `Add` -\> `PCI Device`.
* **Device:** Select your B50 Virtual Function (e.g., `03:00.1`).
* Check `PCI-Express`. Click `Add`.
* **Add Stable Audio:** Click `Add` -\> `Audio Device`.
* **Device:** `ich9-hda`
* **Backend Driver:** `none` (This is critical).
5. **Start the VM.** It is now fully headless.
-----
### Part 2: Headless System Configuration (via SSH)
1. **Connect via SSH** from your client machine:
```bash
ssh builder@<VM-IP-ADDRESS>
```
2. **Enable Multilib:**
```bash
sudo nano /etc/pacman.conf
```
* Uncomment the `[multilib]` section and its `Include` line. Save and exit.
* Sync the repos: `sudo pacman -Syu`
3. **Install `paru` (AUR Helper):**
* *Why:* We need this to install `sunshine-git`.
<!-- end list -->
```bash
sudo pacman -S --needed base-devel git
git clone https://aur.archlinux.org/paru.git /tmp/paru
cd /tmp/paru
makepkg -si --noconfirm
cd ~ # Go back home
```
4. **Install All Software (The One-Liner):**
* *Why:* We use `paru` to install everything from both the official repos and the AUR in a single command.
<!-- end list -->
```bash
paru -S \
vulkan-intel \
intel-media-driver \
sway \
xorg-xwayland \
foot \
wmenu \
pipewire \
wireplumber \
pipewire-pulse \
pipewire-alsa \
pipewire-audio \
pavucontrol \
seatd \
sunshine-git
```
*When/if it asks for a `jack` provider, choose `pipewire-jack`.*
-----
### Part 3: The Headless Service Chain
1. **Grant User Permissions:**
* *Why:* We must give your user permission to access all hardware (`render`, `video`, `input`, `seat`).
<!-- end list -->
```bash
sudo usermod -aG render,video,input,seat builder
```
2. **Enable `seatd` and `linger`:**
* *Why:* We enable the `seatd` daemon, then enable `linger` for our user. `Linger` allows your user's services to start at boot *without* a login.
<!-- end list -->
```bash
sudo systemctl enable --now seatd
sudo loginctl enable-linger builder
```
3. **Create the `sway.service`:**
* *Why:* This defines Sway as a boot-time service. `WLR_BACKENDS=headless` is the magic that creates our virtual display.
<!-- end list -->
```bash
mkdir -p ~/.config/systemd/user/
nano ~/.config/systemd/user/sway.service
```
* Paste this into the file:
```ini
[Unit]
Description=Sway Wayland Compositor (Headless)
[Service]
Type=simple
Environment="LIBVA_DRIVER_NAME=iHD"
Environment="WLR_BACKENDS=headless,libinput"
ExecStart=/usr/bin/sway
Restart=on-failure
RestartSec=5
[Install]
WantedBy=default.target
```
4. **Create the `sunshine.service` Override:**
* *Why:* This forces Sunshine to use the correct Intel `iHD` driver for hardware encoding.
<!-- end list -->
```bash
systemctl --user edit sunshine.service
```
* Paste this into the blank file and save:
```ini
[Service]
Environment="LIBVA_DRIVER_NAME=iHD"
```
5. **Create the Sway Config:**
* *Why:* We copy the default config and modify it for our headless setup. `sudo` is required, as the source is in `/etc`.
<!-- end list -->
```bash
mkdir -p ~/.config/sway
sudo cp /etc/sway/config ~/.config/sway/config
sudo chown -R builder:builder /home/builder/.config
nano ~/.config/sway/config
```
* **Add/Modify** these blocks in the file. (The `wmenu-run` line should already be correct, just verify it).
```sway
# Verify this line is correct
set $menu wmenu-run
### Headless Output Configuration
# This configures the virtual display created by WLR_BACKENDS=headless
output HEADLESS-1 {
mode 1920x1080@60Hz
position 0,0
}
### Input Configuration
input * {
xkb_layout "de"
}
### Autostart Services
# We let Sway start our other services to ensure they
# inherit the WAYLAND_DISPLAY environment correctly.
# The 3-second delay fixes a race condition, giving Sway
# and PipeWire time to initialize before Sunshine starts.
exec systemctl --user start wireplumber.service
exec --no-startup-id /bin/sh -c "sleep 3 && systemctl --user start sunshine.service"
### Aesthetics
# Remove all window borders
default_border pixel 0
```
* **Comment out** the `bar { ... }` section at the bottom to hide the status bar.
6. **Enable the Sway Service:**
* *Why:* This is the only service we need to enable. It will start at boot (thanks to `linger`) and then use its config file to start everything else.
<!-- end list -->
```bash
systemctl --user daemon-reload
systemctl --user enable --now sway.service
```
-----
### Part 4: Final Setup & Connection
1. **Reboot the VM:**
```bash
sudo reboot
```
2. **Wait 60 seconds.** Do *not* log in. The `linger` service is starting Sway, which is starting PipeWire and Sunshine.
3. **SSH Port Forward:**
* From your client machine, run this to securely access the web UI.
<!-- end list -->
```bash
ssh -L 47990:localhost:47990 builder@<VM-IP-ADDRESS>
```
4. **Configure Sunshine:**
* Open `https://localhost:47990` in your browser.
* Complete the first-time setup (create a username/password).
* Go to the **Applications** tab, click `Add New`, and create your "Sway Desktop":
* **App Name:** `Sway Desktop`
* **Command (do):** `/usr/bin/foot`
* Go to the **PIN** tab to pair your Moonlight client.
5. **Connect with Moonlight:**
* You are done. You can now launch your "Sway Desktop" from Moonlight. You will be greeted with a terminal in a clean, headless environment. Press `Mod+d` (Windows Key + D) to launch `wmenu` and run any other application.
If there are any mistakes, feel free to point them out!
Also, add these kernel parameters: pcie_acs_override=downstream,multifunction to break up iommu groups, and xe.enable_guc=3 to enable all hardware functions.

Is this on the host or on the guest?
The details about the virtual display got me further. If I disable the qemu GPU, I can enable a virtual display with mutter -
# mutter --wayland --headless --virtual-monitor 5120x2160
libmutter-Message: 03:00:38.528: Running Mutter (using mutter 48.4) as a Wayland display server

Now when I ssh and start sunshine I can see it actually grabbing the display. When I try to connect, it looks like it is going to work, but I end up with a black screen for about 5-10 seconds and sunshine segfaults.
The output from sunshine just keeps looping over the display detection with the error message about not getting an image reply -

This is more progress than before when it would try to connect, flash a white screen, and crash immediately.
It looks like I was wrong about the above output. The sunshine logs are the same with the mutter display or not unless I set the WAYLAND_DISPLAY env var to wayland-0 from the mutter output.
At that point I see sunshine grabbing the virtual monitor but it is unable to find an encoder when using wayland -

So the only way the encoder is currently found is if I ssh with X11 forwarding on and the DISPLAY env var is set. If I ssh without X11 forwarding, it has no DISPLAY var and therefore no encoder is found by sunshine.
Hey all!
I’ve got a B50 Pro up and running in Proxmox 9, 6.17 Proxmox kernel (not the 6.17 from OP), B50 is using xe drivers (both before and after SR-IOV - ran into issues with using VFIO drivers where I couldn’t set the number of instances for SR-IOV) , SR-IOV setup for 6 instances… All of that seems to be working fine, and I did do the firmware upgrade using the Sept 3 drivers from the OP (latest Pro driver) via Windows prior to using in Proxmox.
The issue I’m running into is that every single VM that I setup to use the B50 GPU crashes with VIDEO_TDR_FAILURE as the cause within igdkmdnd64.sys. This happens whether or not I have a virtual display attached via Proxmox, and happens both via RDP (where I might expect it), and via noVNC console in Proxmox where the B50 isn’t even being used.
I saw one other instance in THIS thread of the same crashing error, but I don’t see a specific resolution. My machine is a Minisforum MS-A2, 9955HX CPU, with 96GB of RAM, latest BIOS (1.02 from June 2025), resizable BAR is enabled, and the PCIe slot is set to Gen 5.
Looking for any ideas on what to try next…
This is a complete tangent, but… How did you get the b50 pro to fit in the MS-A2?
It’s running topless until the n3rdware heatsink comes out.

try the pcie_acs downstream,override options, and their various permutations. might also be helpful to post the output of your ls_iommu with all the VFs enabled.
also the output of dmesg once the tdr error(s) happen.
