HP ProDesk 600 G1 Intel i5-4590: IOMMU?

[chrispazz]

Hello,
I have this hardware and I am running a great Proxmox Installation.
I need to make the integrated video card available to a VM but I am not able to enable IOMMU support.
Currently I have enabled VT/X in bios and I can see in DMESG that kernel enabled IOMMU but when giving a PCI card to my VM it always says that IOMMU is not enabled.

Someone is using the same hardware? I know that the CPU is VT/X VT/D enabled ....

Thank you
Chris

Did you enable the kernel modules and set the kernel commandline? Be sure to check which bootloader you are using because that has an impact where to place the kernel commandline parameters. https://pve.proxmox.com/wiki/Pci_passthrough

Also check if you can enable IOMMU in the BIOS.

Hi AAron,
it seems that the problem could be the motherboard not supporting VT-d.....
Kernel command is ok (grub) and IOMMU is enabled but there is no VT-d support to enable pci passthru...
