Guten Tag, zu erst ein paar Infos: Zum System: ASrock b450m pro 4 R2.0 AMD Ryzen 5 5600G 32 GB RAM Proxmox 8.1.10 root@pve-02:~# dmesg | grep -e DMAR -e IOMMU [ 0.379933] pci 0000:00:00.2: AMD-Vi: IOMMU performance counters supported [ 0.381426] pci 0000:00:00.2: AMD-Vi: Found IOMMU cap...

I am trying to passthrough my lsi PCIe card to openmedia vault and when I add pcie hardware it says no IOMMU detected. The card is detected in lspci, I added `intel_iommu=on iommu=pt` to the kernel and `vfio vfio_iommu_type1 vfio_pci vfio_virqfd1` to /etc/modules and refreshed initramfs...

Moin Moin, ich habe sogut wie alles gemacht, was ich irgendwie finden konnte. Jedoch funktioniert bei mir kein IOMMU, ich möchte gerne meine AX210 WIFI Card zur PFSense durchreichen, wobei die meldung kommt "No IOMMU detected, please activate it.See Documentation for further information." Das...

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, I have a VM host with an ASRock Rack B550D4-4L mainboard with AMD Ryzen 7 PRO 5750G (with Radeon Graphics) CPU running a current PVE 8.1 with Kernel 6.5. # pveversion pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.13-1-pve) The system runs very stable overall, but it only boots...

Hi, I have enabled IOMMU: intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction Tried with "downstream","multifunction" and "downstream,multifunction" Added necessary module options echo "options vfio_iommu_type1 allow_unsafe_interrupts=1" >...

Hello I have a problem with PCI Passthrough. my virtual machine gets such an error: () kvm: -device vfio pci,host=0000:03:00.0,id=hostpci0,bus=pci.0,addr=0x10: vfio 0000:03:00.0: failed to setup container for group 17: Failed to set iommu for container: Operation not permitted TASK ERROR: start...

I had a roadblock today and figured it out, but I want to understand the difference. I configured now three systems with iommu and pci-passthrough. Everytime appending intel_iommu=on at /etc/kernel/cmdline was enough. Those were on a: ASUS Prime Z590-P MSI MEG Z590 ACE ASUS B450M-K II MSI MEG...

That's a lot of words! What I'm investigating if it's possible to pass an AMD Ryzen 5700U iGPU (sorry, it's a Mini PC with dual HDMI) to an LXC guest (Flatcar LXC), which in turn holds Plex. While the above is critical for video hardware encoding, the main idea is for GPU Split Passthrough...

Goal - Have hardware transcoding on a virtual machine using a GTX 1070 TI as the GPU. Achieved so far from following https://pve.proxmox.com/wiki/PCI_Passthrough#Enable_the_IOMMU. I have gotten so far to the point now where running nvidia-smi will show me Picture 1 in the VM. I can't get this...

I've got two identical NVMe drives (same model, same capacity) in my system. One drive I use for PVE storage. The other I'd like to passthrough to a vm. When I go into the settings of the vm, Idk which drive to select, because Idk which one is which. On the disks overview on the node, the...

Hi, I changed motherboard and CPU recently on my server and a lot broke. But finally, when I got proxmox to boot and got access to the web interface, I have to passthrough my PCIe devices again. The problem I am running into is that when following the guide PCI Passthrough, when I run; dmesg |...

Hi all, First off, I just started trying to get GPU passthrough working for the first time. I'm a noob and gradually learning this stuff, so thank you ahead of time for your patience and help with getting me through this Not far on the road, I stumbled into a roadblock, IOMMU isn't enabling as...

I'm composing something on my blog. Was wondering if there's anything I can crib notes from. I'll do lspci and put in the bits about blocking the kernel module from loading using /etc/modprobe.d/blacklist.conf ; anything else we should include?

Hi all, first off, I'm a noob and gradually learning this stuff, so thank you ahead of time for your patience and help with getting me through this Secondly, I promise I've spent days researching the answers myself before creating this thread. I've followed the guides, the official docs and I...

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...

Hello I have installed Proxmox VE on an HP EliteDesk 800 G3 CPU: Intel i5-6500 65W Chipset: Intel Q270 As per intel specs (available at https://www.intel.com/content/www/us/en/products/sku/88184/intel-core-i56500-processor-6m-cache-up-to-3-60-ghz/specifications.html ) the CPU supports all this...
