---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.

---uname output---
Linux c158f2u09os 4.8.0-26-generic #28-Ubuntu SMP Tue Oct 18 14:41:40 UTC

Machine Type = 8247-22L
---Debugger---
A debugger is not configured
---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:~#
