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...

Has anyone had success with passing through the Intel ARC A770M (or similar) to a VM (Windows or Linux)? I think I have vfio binding mostly working, however when I attempt to start the Windows 11 VM, it complains about VFIO being not ready/giving up on resets (causing the Proxmox task to...

I've been trying to pass my RX 7900 XT to a Windows 11 VM on Proxmox 7.3. I only manage to get video output via HDMI for the first few seconds while it's booting (showing the Proxmox logo, OVMF?). Then it stops, and it doesn't show anything on subsequent boots. I had the same hardware before...

I was previously using Proxmox 6.1 and passing through my RX480 to a windows guest. It was working smoothly, except for the issue of unexpected guest shutdowns making the GPU unusable until the system did a full power cycle. I updated to Proxmox 7.3 and the windows guest stopped working. First...

Hello all, I have a problem with passing through the primary GPU but have no problem with the second one. The problem is that when trying to start the VM with the primary GPU attached returns --> Dec 30 18:14:44 pve kernel: [ 889.165695] vfio-pci 0000:01:00.0: vfio_ecap_init: hiding ecap...

I am running into a problem where I am trying to pass the Intel IGD to any virtual machine (Windows, macOS, Ubuntu) , but vfio runs into FLR problems where the IGPU appears unresponsive. As of right now, I've tried to make it work on Proxmox VE 7.0, 7.1 and 7.2, but to no avail. I am running...
