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...

Hi! So as the title says I'm trying to passthrough the PCI card to a Windows 7 VM. This card has both a Firewire controller as well as a SATA one. I have the two controllers bound to vfio, IOMMU is enable, the drivers for the controller are blacklisted and I have followed the official tutorials...

My goal is to connect my GPU (RX 580 4gb) to the VM so that I use the VM on host PC with it. I set display to none and in hardware connected PCI Device (GPU). But when I try to startup the VM, I get this response: Any idea how to fix this? In advance, thanks for your response.

Hi everyone! I recently install Macos Monterey on Proxmox 7, everything is fine, i can install it without problem. I use OpenCore and setup OVMF as Bios. The problem is, when i try to passing my GPU to MacOS, i've got a blank screens, nothing happen... But VM start properly ( i guess cause it...

EDIT: this is the output to lscpi -v on Proxmox host: Does this mean that the kernel is still using the card? Should I also blacklist amdgpu as well? 83:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 (rev ff) (prog-if ff) !!! Unknown header type 7f...

Hello, I have PVE 7.0 running on a Gigabyte H310N motherboard with intel i5-8400. The IOMMU setup was done following the wiki. The motherboard has an M.2 slot for wifi card, and I have a Coral TPU installed on it. The IOMMU group looks good: IOMMU Group 0: 00:00.0 Host bridge [0600]...

Hello world! I am trying my hand at a slightly unusual set-up of Proxmox. For my home desktop (Intel X99 plattform) I want to run Proxmox headless and instead give the main graphics card (AMD R9 380x Nitro in Slot 1) to a Linux VM and the second graphics card (NVIDIA GeForce GTX 980Ti) to a...

This is the error code 1 for my 300 VM: kvm: -device vfio-pci,host=0000:42:00.0,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0,x-vga=on: vfio 0000:42:00.0: failed to open /dev/vfio/56: Device or resource busy start failed: QEMU exited with code 1 failed to open /dev/vfio/56 - say what? What is this?

Hi, i've camed in another thread to the Problem, that there is no easy way to bind vfio-pci to a bus device. This is neccessary if you can't do it with vendor:device id, because you have multiple devices and you need them on your host too. For example, if you want to passthrough one of four nic...

First of all I would like to thank the Proxmox team for the great software and the nice community they built. I'm using a custom hook script (hookscript.pl) to manage VMs on a system with various GPUs passed through. The first motivation to do so is to avoid a VM (which requires a GPU) being...

Hello everyone, we have a H11Dsi running Proxmox 6.3-3 and latest BIOS. System boots off of NVMe m.2 SSD. What we want to do is, pass through the onboard SATA Lan controllers. What we tried is: $ cat /etc/modprobe.d/vfio.conf options vfio-pci ids=1022:7901,15d9:7901 lspci confirms the...

Hi ! I'm really new to Proxmox and virtualization. After successfully install MacOS on proxmox at my home, i want to try install macos Catalina with Opencore on an old pc. Installation is a success but when i try to passthrough my GPU i've got a blank screen.. I try with Vmware compatible...

I have 2 GPUs in my system (both AMD) successfully passed through and working at near-native performance. One of the VMs is my primary workstation so the onboard sound is also passed through. This VM, however, has issues with garbled audio. I listen to music all day on this computer and...

Hello, Sorry if this question is very simple, but I have no idea about where to apply the said device in the title, that is from this link: https://forum.level1techs.com/t/increasing-vfio-vga-performance/133443 As an attempt to fix the AMD Reset Bug I knew that the config files of the VM sit...

I have seen a suspicious behavior of my GPU-passthrough VM (Linux) for quite some time. That is no matter how small the actual memory usage is (even when the ballooning is enabled), upon starting the VM, it will "try" to allocate the full memory (as configured). This doesn't mean that ballooning...
