Hey guys, we do a PCI Passthrough of a TRX 4060 TI on a B650D4U-2L2T/BCM mainboard with an AMD Ryzen 9 7900X CPU. I got the passthrough working yesterday once after a CMOS reset followed by reapplying these bios options (I verified working passthrough using nvidia-smi in the VM), but after...

Iommu group 0 contains all pcie slots and more stuff I can't passthrough into the vm, I've tried passingthrough nic and usb header it worked as a charm. But when I wanted passthrough my hba I couldn't because of the problem I mentioned. Does anyone know a solution?

System Configuration: • RTX 3090 (working successfully) • RTX 3090 Ti (causing crashes) • Storage: (NSF) • Power Supply: (e.g., 1600W Platinum) The Issue: I am attempting GPU passthrough for an RTX 3090 Ti on Proxmox to a virtual machine (VM). While I have...

I got the following error when backing up overnight: ERROR: Backup of VM 114 failed - PCI device '0000:15:00.0' already in use by VMID '107' Now I know why this is - just as it says, the PCI device (a GPU in this case), is already in use. However, I wonder what the recommended solution is? I...

Hello, I have recently set up successful GPU passthrough for 2 dGPUs and the iGPU on a Proxmox machine. Proxmox itself uses the IPMI/BMC graphics for displaying the console. Everything seems to be working well besides the occasional crash, which I'll eventually work out. My issue is regarding...

Hello, I use proxmox with kernel: # uname -r 6.8.12-2-pve I have ASUS Radeon RX 7900 XTX TUF Gaming OC 24GB GDDR6 installed in PCI slot From proxmox I can see it as: 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 XTX] (rev c8)...

Hi all! I'm trying to get a Intel ARC into a VM. I think i made some progress but just wanted to check with you all to see what i could be missing. Both cards use i915 so i don't know if i can blacklist without creating new problems because 00:02.0 is still being used for Proxmox VE. #...

Hello, I am attempting to pass through 2 NVMe drives to two different VMs. They are on an Asus bifurcation card with a total of 4 m.2 slots, all of which are populated. My BIOS has the PCIe slot set to x4x4x4x4 and all of the drives are seen correctly in Proxmox. Hardware is listed at the...

Hi, I have been reading about vhost-user and specifically vhost-user-gpu, which is used alongside VirGL/Venus on QEMU to provide "pieces"/"slices" of a GPU from the host to Guests/VMs. The problem with this is that using `dpdk`, this is running in user-space instead of kernel space, which is a...

If you have a laptop in "Developer Workstation" mode and you want to use it with the Nvidia graphics card, you have come to the right place. The first step is to read and apply the instructions presented in my other tutorial ...

(Crosspost from r/Proxmox) I have a libvirt VM (QEMU/KVM based) that has CPU pinning, PCIe device passthrough, iothread and other optimizations (it is a VFIO gaming VM) in a Fedora host. I will install Proxmox in this machine soon, and I want to recreate the gaming VM inside it. How do I...

How does Proxmox (8.1.10) set VFIO automatically? I have a VM, with passed through PCIe NVME. I am having issues with speeds on this, so wanted to test the zpool on the host machine. All devices SEEM to be passing through fine I am new to proxmox, but previously used libvirt. I have set...

Hi, i am trying to understund why the system behave this way to find out where the issue lays, system specifications and and steps taken in attempt to fix it bellow: CPU: G4400T / I5 6500 (tried both) RAM: 16GB (2x 8GB) Motherboard: ASRock H110M-DGS R3.0 (BIOS: P7.4) NetworkPVE: RTL8111 GbE...

Hi! so I switched back from ESXi to Proxmox and I am now having issues getting video output over VGA/IPMI. The motherboard is the Supermicro H11SSL-i. As soon as a VM starts, the console goes blank. When I look at the syslog, I see the following output: Feb 01 12:42:50 proxmox pvedaemon[4247]...

Hey Ho zusammen, ich habe ein Problem was ich einfach nicht gelöst bekomme. Das Problem: ich versuche einen Sata Controller (ASM1166) an eine VM durchzureichen. Erstmal ist es nur eine Basis Windows Server 2019 Datacenter Eval. Wenn ich die VM ohne die PCI Karte starte geht alles super. Füge...

Recently upgraded from PMX7 (Proxmox Version 7 or PVE7) to PMX8 (Proxmox Version 8 or PVE8), and I noticed the passthrough doesn't seem to work the same way in the UI it used to. <= PVE7, the way you knew IOMMU/etc wasn't working is that in the UI, the "MAPPED DEVICES" dropdown would be empty...

Hey all! I have struggled with GPU passthrough many a times as many before me. I have had a cluster of two PVE nodes prior that failed to have stable GPU passthrough so I had given up until now. I am testing in a single PVE instance with two GPUs. Both AMD and Nvidia are present in the server...

Hi everyone, I'm losing my sanity a bit on this topic and I would like your previous help, let's begin! I passed the pcie as per the doc and installed Nvidia drivers from Nvidia, no nvidia-smi available but the driver seems there, also the gpu name doesn't appear on lspci but...

Hi Folks, I am getting VIDEO_DXGKRNL_FATAL_ERROR error when i do load test like Passmark This is very random, 90% time this error happens with in the first test. Note: If i switch to KVM64/QEMU 64 this crash does not happen strangely My Hardware/Software AMD 5900X 32GB DDR4 RAM @ 3200MHZ...
