Hello thank you for your feedback :) I followed your advises and and I did those steps : - I shutdown the windows vm on my proxmox server - Once the vm was shutdown i disabled start on boot and I rebooted the system - The only vm still running was a truenas one and then I followed by...

Oh I see, I have two 1650 GTX, B550 Plus Wifi Tuf Gaming and 5700G, if iGPU passthrough is not recommended, can I use both 1650 for that build? One for a linux NAS, one for Windows to render videos in Premiere Media Encoder

I am seeking assistance with passing through the integrated GPU from a Ryzen 5 5600G to either a VM with several LXC containers or directly to a Linux Mint VM. I have successfully passed through an AMD RX 580 GPU to a Windows 11 VM, and it works flawlessly. However, I'm encountering issues with...

Hello, and thank you for reading this. I've taken on a challenge to build a server using consumer-grade components to run 6 VMs, each with its own dedicated GPU. The number 6 is only because the motherboard has 7 PCIE slots which one will be used for a GPU dedicated to the host. However, my...

Hi everyone, I'm having some issues with one of my pve hosts. I'm hoping you guys could point me in the right direction since I'm a bit lost at this point... I have been encountering random crashes on this node: pve web UI unreachable SSH to the node: ok VMs: unreachable Seeing crash logs...

[edit] thank you, I found the solution in a reply you did in another post https://forum.proxmox.com/threads/solved-asus-tuf-b550-plus-and-iommu-groups.85250/post-374392 and this video https://www.youtube.com/watch?v=UgIUPZWBu9c thanks again -------------------- Sorry, that was my first...

Please don't start a new and totaly different issue in solved threads. Just start your own. You NIC is probably part of the big Ryzen chipset IOMMU group. You cannot passthrough one device in a IOMMU group without the Proxmox host losing all other devices in the group. Check your groups: for d...

Story background: Machine is operating with Proxmox 7.3.6 and successfully passthrough GPU in Windows 11 VM (works perfect in windows VM) Recently, I did gpu passthrough to Ubuntu vm which can output video signal from GPU hdmi port but Nvidia driver still not detect the GPU. Please Help GRUB...

Just an idea, could it be that IOMMU group 15 02:00.0 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] Device [1022:43ee] is wired to the ports on the back and IOMMU group 23 0b:00.3 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller [1022:149c] is...

Every Ryzen motherboard except X570 has a big "chipset" IOMMU group and has the same issues. A separate USB controller PCIe card won't help because it will probably also end up in that big group (unless you put it in the x16 slot of the GPU but then the GPU passthrough will give you trouble)...

Ah thanks and you seem to be right. Its Group 15 with LAN Controller included. So this means I only can add everything from the IOMMU Group and can not specify (subgroup) it any more, right? - I understand a sperate USB Controller would be the best but than I would rather route every USB Port to...

No, the devices in slots with PCIe lanes connected to the CPU should be in separate IOMMU groups. I would expect the first PCIe x16 slot and the first M.2 slot and the integrated graphics to have separate groups. Maybe update your motherboard BIOS, as some versions have poor groups and...

test reply Yes, this is the case! Everything is in the big chipset group without the patch. One question regarding that: Its always the cas without X570 chipsets? So if I'd buy a Desktop Mainboard with B550 I have the same trouble? Is Ryzen 7000 known to also have these problems? root@pve:~#...

I think with a B550 you only got one PCIe slot that can be used with PCI passthrough because all other slots are connected to the chipset and not directly to the CPU. You will have to test that, but probably that slot won't get a dedicated IOMMU group.

Thank you so much for your answers and for claryfing things for me @Tahsin and @leesteken. I am currently using ASRock B550 Steel Legend. Can you please explain to me how would I post my settings for modules, modprobe, and cmdline? I am very new to Proxmox and the whole HomeLab virtualization...

The PCIe x16 slot (and the M.2 slot) closest to the CPU ought to be in separate IOMMU groups on Ryzen B550, otherwise you need to try another BIOS version. But putting the GPU in the first slot probably also causes the system too use it while booting, which can give reset issues for passthrough...

Thanks for the reply. I moved the controller to the first slot and now it's working as expected. I had to move my gpu to the second slot for now...

On the B550 motherboards only the first x16 PCIe slot and the first M.2 slot are in their own IOMMU group (provided by the CPU). You need an X570 (or X470/X370 with two x8) for this. pcie_acs_override=downstream,multifunction will lie about the groups and also break the security isolation...

Hi leesteken, I got a new Asrock X570 PG riptide mobo (X570 chipset) and indeed that dit the job. The IOMMU groups are hugely better than the Asrock B550M PRO4 (B550 chipst). IOMMU group 0 00:01.0 Host bridge [0600]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse PCIe Dummy Host Bridge...

I am attempting to pass through my main gpu (GTX 760) on an B550 Aorus Master MB with an amd 5900x processor. (I do not need the GPU on my system and am perfectly comfortable managing things through ssh and the web interface.) I have followed the guides and my GPU IOMMU group seems to be...
