I'm trying to bind a NIC to pci-stub or vfio-pci at startup so my libvirt-managed VM can use it on autostart, but the NIC keeps being claimed by ixgbe. I tried

  1. inserting into /etc/initramfs-tools/modules vfio_pci ids=8086:10fb
  2. running sudo update-initramfs -u -k all

and I also tried using pci_stub instead of vfio_pci but whenever I reboot and run lspci -nnk I see the NIC is still claimed by ixgbe. What am I doing wrong?
