Whilst reviewing the code I think that I have stumbled on an issue (I hope that I am mistaken). The change set (https://review.openstack.org/#/c/35749/) expects pci stats to be returned from the host. There are a number of issues here that I have concern with an would like to know what the process is for addressing the fact that the compute node may not provide these statistics, for example, this could be due to the fact that the driver has not been updated to return the pci stats or this could be if the scheduler has been upgraded prior to the compute node (what is the process for the upgrade).
