[john335745634]

Hi guys,

I am trying to passtrough a NIC on a i5-6500, however it fails


I added to nano /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"

and I get

Does your motherboard and CPU both support VT-d and is it enabled in the BIOS?

EDIT: You already showed /proc/cmdline and intel_iommu=on is not there! Either your Proxmox does not use GRUB or you did not run update-grub and/or reboot after making changes for PCIe passthrough.
