Gary Firstly, thanks for your review very much. The pci_stats is calculated in the resource tracker in the compute node and is also saved in compute_node, I think currently the scheduler depends on the information provided by the compute_node table so this method should fit

IMHO, this seems fit better of the availability since location is more about availability like power supply, network switch availability etc. Or, what's the boundary of host aggregate and availability zone? Seems host aggregate is so magic that it can cover every requirement to separate/group
