Public bug reported: == Comment: #0 - SRIKANTH B. AITHAL <[email protected]> - 2016-10-26 01:40:39 == ---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.

After booting into Ubuntu 16.10, see if vfio_pci modules are loaded: root@c158f2u09os:~# lsmod | grep -i vfio 2.
