Description of problem: Sriov instance's spawn fails if additional properties "hw_vif_model & hw_disk_bus" in image If we add the below metadata properties to image, and any VM launched with this image is moving to ERROR state due to failure of SRIOV port binding ~~~ hw_vif_model = virtio hw_disk_bus = virtio ~~~ Error Message:- u'message': u"unsupported configuration: Unknown PCI device <driver name='vhost'/> has been specified", u'code': 500, u'details': u' File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 1862, in _do_build_and_run_instance\n filter_properties, request_spec)\n File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 2142, in _build_and_run_instance\n instance_uuid=instance.uuid, reason=six.text_type(e))\n The above is strange as why would a Sriov instance have 'vhost' as a driver? A sriov interface should be seen as vfio device in libvirt. Version-Release number of selected component (if applicable): RedHat OpenStack Version 13.0 How reproducible: Steps to Reproduce: 1. Add additional property to image:- ~~~ hw_vif_model = virtio hw_disk_bus = virtio ~~~ 2. Spawn a sriov instance Actual results: Instance spawn is failing:- ~~~ u'message': u"unsupported configuration: Unknown PCI device <driver name='vhost'/> has been specified", u'code': 500, u'details': u' File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 1862, in _do_build_and_run_instance\n filter_properties, request_spec)\n File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 2142, in _build_and_run_instance\n instance_uuid=instance.uuid, reason=six.text_type(e))\ ~~~ Expected results: Instance spawn should not fail.
