I’m trying to set up GPU Passthrough with Ubuntu 24.04 LTS using KVM on a HP Proliant DL360 Gen 9. The videocard I’m using is a NVIDIA GeForce 730. Ubuntu sees the videocard when I use “lspci | grep NVIDIA”.

I’ve tried 20 or 25 tutorials on the web so far and none of them seems to work. All those tutorials result in this error:

“vfio 0000:11:00.0: failed to setup container for group 32: Failed to set group container: Invalid argument”

and also in dmesg: “vfio-pci 0000:11:00.1: Firmware has requested this device have a 1:1 IOMMU mapping, rejecting configuring the device without a 1:1 mapping. Contact your platform vendor”

Things I’ve tried:

  • Checked if Virtualization is enabled, which it is
  • Enabled IOMMU in /etc/default/grub
  • Adjusted grub to exclude the driver and device from the host so that it can be used by a VM
  • The videocard has been added to IOMMU group 32 with ID 0000:11:00.1

lsmod | grep vfio:

vfio_pci               16384  0
vfio_pci_core          94208  1 vfio_pci

vfio                   73728  3 vfio_pci_core,vfio_iommu_type1,vfio_pci

irqbypass              12288  2 vfio_pci_core,kvm

lspci -nnk:

dmesg | grep -i -e DMAR -e IOMMU

/etc/default/grub:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`( . /etc/os-release; echo ${NAME:-Ubuntu} ) 2>/dev/null || echo Ubuntu`
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt kvm.ignore_msrs=1"
GRUB_CMDLINE_LINUX=""

Tutorials that I followed and all of them end up with the same error (Some of them were on AlmaLinux):

When I search for that Firmware error in dmesg it only shows Proxmox topics and they offer a new Promox kernel as a solution, but I’m not using Proxmox, so no solution for me. What am I doing wrong here? I’m really at my wits end here. Thanks in advance.

P.S. I'm not very familair with GPU/PCI Passthrough, so if I forgot to provide any useful information, let me know.

I managed to fix this issue by myself. I used hardware from a different brand and it works like a charm now.
