gpu passthough

I'm struggling getting 2 Nvidia GPUs to passthrough to the same VM. I've been able to do this before even passing 4 GPUs to the same VM (using 1x Riser Cables). But now that I'm trying to passthrough the 2 GPUs actually connected directly to the x16 PCIe ports, I only seem able to pass one or...

I have a Linux VM set to have GPU pass through. This allows me to use the host's HDMI output for it. I'm wondering if there is a way to also have the same (mirrored) output through the Proxmox console. This would be handy while troubleshooting, doing lots of that! :D

Hi, I acquired some '' old '' component and I want to swap then in my home lab. I'm actually using a i7 2600k and just found a 2700x. But I'm running a window vm in which I passed a 1070ti. I use the igpu from the i7 for proxmox. But here I don't have any with the 2700x. Can I use a second...

I have a beefy laptop that I have contemplated for a long to turn into my virtualization platform. It is maxed out with 128 Gigs of RAM and an nvidia RTX 5000 that has 16 GB GDDR6. Memory Interface. My primary consideration revolves around the potential underutilization of the GPU in the event...

Hi everyone, I have already tried to do GPU Passthrough, but without success, here is my configuration: - Ryzen 5 5600G - RX 6750 XT - CoolerMaster 800+ Gold - 2x8Go RAM - Omen motherboard from a pre-build pc The motherboard is very low end, so I can't unlock anything in bios. There is almost no...

Hi!, I am not really sure it's data corruption but it just seems like it. So, I have 2 vms that have separate GPUs assigned to them. When I start both of them, the one vm freezes for a bit and then it starts working again, but after I turn off the pc and boot it up again I get fsck on the screen...

Hi, I have just done a clean install of PVE 8.1.3 after changing some hardware in the host. I have restored my Plex LXC and some of the groups have different IDs in the container than the host which is breaking my GPU transcoding. The render group is ID 107 in the LXC but 104 on the host. On...

Hi everyone, I tried running Proxmox on a laptop and it seems to be working great, except for the iGPU passthrough for Windows. I took a look at the following documentation: https://pve.proxmox.com/wiki/PCI_Passthrough This documentation seems to be working fine for Ubuntu but not in any shape...

I just finished migrating my Windows 11 gaming VM from Unraid to Proxmox. Along the way I encountered some obstacles. To hopefully save other people some time I'm writing a detailed guide here on how I set up my system. Disclaimer: I am by no means an expert on this stuff. It is entirely...

Hi everyone, Whenever I run the CPU as host (needed for WSL2 afaik), I end up with the VM crashing every 11 minutes or so, or whenever I scan for hardware changes in the device manager. The BSOD is: VIDEO_DXGKRNL_FATAL_ERROR I have tried googling around to no avail. My setup: CPU: Ryzen 9...

Good morning everyone! I've been wrecking my brain for the last 2 days looking everywhere to get my RTX 3090 to passthrough without Code 43 error. Current Setup: Mobo: Crosshair VIII Dark Hero CPU: Ryzen 5900x No Integrated GPU (But I have a second RTX3090 and have tried using both)...

Hello everybody! I have a DeskMeet B660 with intel i3 13100 CPU, 32GB ram and an RX6600 GPU. Right now I am using unraid and it works for making windows VM and passing through the GPU. My only problem was that I had to turn ON CSM and disable rebar and so on to make it work, so my question is...

Hi everyone! I just release a new post detailing my journey in setting up an AI Homelab, covering everything from hardware choices to software intricacies (Proxmox, GPU Passthrough, Managing multiple env). The blog post is here ...

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...

I have an active Ubuntu server 22 VM that I want to pass through a GPU (p2000) for hardware acceleration. Now when I set up this VM a long time ago I used the default machine (i440fx) and boot type (SeaBIOS), but the docs don't recommend those options for passthrough. The machine type was...

I wanted to isolate different tasks in VMs (Windows for gaming, something with Portainer for Docker containers and a Linux desktop for Python AI stuff), that are using one GPU and I’m a bit surprised about how challenging that seems to be, considering that virtualization is a big thing today...
