This is due to https://review.openstack.org/#/c/202616/
The kilo node can't understand 1.2 PCIDeviceList.
Then when kilo compute node retry building instance request send to
liberty conductor will get error as below:

This is due to
https://github.com/openstack/nova/blob/master/nova/scheduler/utils.py#L59
didn't return True anymore, because the kilo node renturn InstanceV1, not
InstanceV2.
