  ---Problem Description---
  vfio_pci is not loaded by default on Ubuntu 16.10 host boot. All VFIO related 
tasks would fail without that module. For instance I was trying to boot guest 
with QEMU directly and it was failing complaining 
"/sys/bus/pci/drivers/vfio-pci/new_id" not present.

  root@c158f2u09os:~# lsmod | grep -i vfio
  root@c158f2u09os:~# modprobe vfio_pci <-- need to load explicitly
  root@c158f2u09os:~# lsmod | grep -i vfio
  vfio_pci               51735  0
  irqbypass               5567  1 vfio_pci
  vfio_iommu_spapr_tce    14567  0
  vfio_virqfd             4859  1 vfio_pci
  vfio                   31351  2 vfio_iommu_spapr_tce,vfio_pci
  vfio_spapr_eeh          3441  2 vfio_iommu_spapr_tce,vfio_pci

  Either 
  > we need to have these modules loaded by kernel by default 
  or 
  > we need to update https://wiki.ubuntu.com/ppc64el/CommonQuestions telling 
customers to load vfio_pci module explicitly before attempting any vfio tasks.

  ---Steps to Reproduce---
   1. After booting into Ubuntu 16.10, see if vfio_pci modules are loaded:
  root@c158f2u09os:~# lsmod | grep -i vfio
  2. After that we need to manually load vfio_pci
  root@c158f2u09os:~# modprobe vfio_pci
  root@c158f2u09os:~#
