Public bug reported: When boot more than one instance with accelerator, and the accelerators are in one compute node, there will be two problems as below:
One problem is as we always get the first item(alloc_reqs[0]) in alloc_reqs, when we iterator the second instance, it will throw conflict exception when putting the allocations. Another is as we always get the first item in alloc_reqs_by_rp_uuid.get(selected_host.uuid), the selected_alloc_req is always stable, that will cause the values in selections_to_return are same . In fact, it's not right for subsequent operations.
