Search results for query: IOMMU not present

Hi @magik6k thanks in advance for the time you put into that! The link to the patch is currently missing, but if you add that i'd be happy to try it out.

I tracked this down and it appears to be a real megaraid_sas driver bug, not just a generic firmware/BIOS issue. Root cause: `megasas_make_prp_nvme()` can write past the end of the 4K PRP chain-frame buffer when building large NVMe PRP lists. The telltale signature is exactly what shows up in...

...On a reboot one of my VMs that has my 1050 Ti passed through to it will not start (TASK ERROR: cannot prepare PCI pass-through, IOMMU not present) Virtualization is (still) enabled in my bios (tried once disabling IOMMU & virtualization, rebooting, and then enabling them again - did nothing)...

> Glad to hear that you issue has been solved! Just to confirm, as far as I can understand, the issue has been fixed by a combination of BIOS update + OVMF in the VM, correct? Yes! dmidecode -t bios # dmidecode 3.6 Getting SMBIOS data from sysfs. SMBIOS 2.8 present. Handle 0x0000, DMI type 0...

I have to dig out this thread because I can't get the driver for a TBS 6922 PCIe card installed on the current Proxmox host (6.17.13-1-pve kernel). I have very limited experience, so when the provided instructions don't work, I'm out of ideas. I installed all the prerequisites mentioned here...

Thank you for your quick reply. I understand your point. So far, I have been able to get GPU passthrough working for all previous scenarios. Even with the new GPU upgrade to an RTX 5090, it still works. It is just strange that these two GPUs can not work. I also tried different physical slots. I...

Hi, I'm trying to passthrough an NVIDIA GPU to a Windows 11 VM on an older AMD platform and I’m hitting a VFIO / IOMMU issue on Proxmox VE 8 with all recent kernels I tried. Hardware: - Mainboard / chipset: HP ProLiant DL380 Gen9 - CPU: 32 x AMD Opteron(tm) Processor 6376 - GPU for...

After a day of hacking around with Chat GPT I've managed to get iGPU passthrough on Proxmox VE 9. Ive asked Chat GPT to write a summary of what we did to get this going. Hope this works for you. Note massive credit goes to https://www.youtube.com/@Automation-Avenue His video is at this link...

Hello everyone, I’m trying to understand the correct expectations and support boundaries for GPU passthrough on DGX / HGX B300 platforms when using Proxmox (KVM/QEMU). Environment: - Proxmox VE (9.1.4 ) - Machine type: q35 - BIOS: OVMF (UEFI) - IOMMU enabled, vfio-pci used - Host platform...

Yes, those are the best practices I have been following. I just tried using the v1.0.271 of the virtio and I have the same results. 40% into installing windows it fails. This is a test environment I am working on so I am using a desktop as the host with the following hardware and software...

Better off with a Dell HBA330. It's a LSI 3008 IT-mode controller chip anyhow. Just make sure to update the firmware to lastest version at dell.com/support

After some long hrs looking into this with ChatGPT this is the conclusion that we have come up with for this issue. As such i will be looking into buying an LSI controller in IT mode to replace the H330. Please note, this is a summary that GPT generated and is not entirely comprehensive of...

Hi everyone! I just wanted to write a guide for those (like myself) trying out GPU passthrough with the HP ProDesk 600 G1 in 2025... I needed to enable VT-d using the "Replicated setup" method (previously mentioned here) in the UEFI/BIOS as the VT-d option was not present in the menus (GUI)...

Absolute newbie here (1 month of using proxmox) and this is my first post to proxmox forum as well. I've been trying to get hardware acceleration up and running for days and seem to have made progress so thought I would add my two cents here. I have spent days going in circles with chatGPT on...

This drives me crazy. It has been posted a bunch of times but apparently I found the 99th time that is not working. What I did so far is check the following: First I've checked if my CPU and System can support it (according to...
