pci passthrough

I have a little fanless mini pc I'm using for Proxmox to run OPNSense and Home Assistant and I'm trying to pass through my wireless interface to the OPNSense VM. The Amazon listing is no longer available, but this was the description of the item: Here are the cpu specs: Intel I3-4005U I...

Problem Description: I am experiencing an issue where an Intel AX200 (Archer TX55E) wireless card, passed through to an OpenWrt VM (OpenWrt 24.10.2) on my Proxmox VE host, is unable to transmit (TX power remains 0 dBm). This appears to be a regulatory domain issue within the VM, but I want to...

Hello Guys, Server: PowerEdge r630 I have 2 RTX 5090 GPUs, I got a riser and attached the first one and was working perfectly without any issues. Then, I connected the second one through the butterfly-riser PCI. And the second one was not getting detected then when i removed the second one...

Hi all, I’ve been running a Proxmox server set up for heavy simulations. The idea is simple: I only run either the Windows or the Linux VM (never both at once, I am using a hookscript), and I want them to use as much CPU and RAM as possible. There’s also a TrueNAS VM running permanently to...

Hello, I am experiencing an issue with USB passthrough when connecting multiple TTY USB devices through a USB hub attached to a PCI Express port. The setup and problem are as follows: I connect a single TTY USB device to the USB hub and pass it through to an Ubuntu 22.04 VM using the Proxmox...

Hello! I've been following this guide from Craft Computing on Youtube to create a Bazzite gaming VM that I can access remotely. He includes a link to this cheatsheet for passing through a GPU to the Bazzite VM. I've followed the guide meticulously for my Dell RTX 3070, but I get this error...

Hello! -------------------------- TL;DR: Proxmox server with PCI passthrough to Windows and Linux VMs was working. BIOS and/or microcode updates broke PCI passthrough to Linux VMs only. Booting Linux VM w/ PCI initially crashed whole proxmox server. With some changes, Linux VMs w/ PCI now...

Hello, Issue Description I am experiencing an issue with USB passthrough when connecting multiple TTY USB devices through a USB hub attached to a PCI Express port. The setup and problem are as follows: I connect a single TTY USB device to the USB hub and pass it through to an Ubuntu 22.04 VM...

I have a win10/11 VM that is used via noVNC (RDP cannot be used), but I need hardware OpenGL. I know that if you insert a discrete video card into a computer with integrated graphics and connect a monitor to the integrated graphics, then it may or may not have OpenGL provided by the discrete...

I am writing this up for several reasons To increase my own understanding of the problem (I still haven't wrapped my head around it entirely) Not wanting to take the simple answer as the solution Documenting the issue for the community so people don't have to spend the time wading through...

The pve host is an Odroid H4+ computer with Intel N97 Alder Lake CPU running lastest Proxmox VE 8.3 I'm trying to passthrough the I2C PCIe controller so that I can see my I2C devices from inside a VM. From the pve host OS the I2C bus is handled correctly and I can see a test I2C device The...

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...

Hello Everyone, 1. I created a TrueNAS VM, and tried to passthrough a WD Red SN700 2TB NVMe. When I start the VM, I get the following message: error writing '1' to '/sys/bus/pci/devices/0000:0b:00.0/reset': Inappropriate ioctl for device failed to reset PCI device '0000:0b:00.0', but trying...

Good evening, I have a 2018 Mac Mini running proxmox 8.3.2. I've recently attached a thunderbolt eGPU with an NVIDIA 3070 GPU. I've followed countless guides, forum posts, etc. to try to get this working in a Debian 12 VM, to no avail. I can get the passthrough "working" as far as the GPU...

Passing my 9300-16i (it-mode) works as expected in both Windows and TrueNAS. When I attempt to add the pci passthrough for my Ubuntu VM, which works otherwise, it will not start. No console output, no green "play" icon, it just sits forever. I'm unable to press 'e' to get to any menu, as the...

Hello, I am struggling to get audio passthrough working well on one of my Proxmox machines. I have tried USB and PCIe passthrough and in either case I get minor crackles on occasion, but it's a bit better when using PCIe passthrough although still not acceptable to me. I believe the devices...

Here are some breadcrumbs for anyone debugging random reboot issues on Proxmox 8.3.1 or later. tl:dr; If you're experiencing random unpredictable reboots on a Proxmox rig, try DISABLING (not leaving at Auto) your Core Watchdog Timer in the BIOS. I have built a Proxmox 8.3 rig with the...

Hello all, i have a problem with PCI Passthrough "Cavium QLogic 425/825/42B/82B 4Gbps/8Gbps PCIe dual port FC HBA" to VM. i follow the https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.thomas-krenn.com/en/wiki/Enable_Proxmox_PCIe_Passthrough And i have on the hosts...

I'm not 100% clear on this and I've searched the forums for an answer... perhaps someone knows and can share their experience. I installed PVE about 10 months ago, I used the CLI method to enable PCI passthrough... then there was a later PVE update that allows this to be done through the GUI. My...

I trying to get PCI passthrough work with my gpu pve servers: UEFI boot with less than 8 Nvidia RTX 3090, win10 and ubuntu 22.04 is boot fine without any issue; but won't boot for 8 cards, not booting from disk(can not find bootable disk), both win10 and ubuntu. I tried: Turn off security...
