If neutron is configured to support qos minimum bandwidth policy rules and the [DEFAULT]/host config option is set for both nova-compute and neutron (sriov / ovs) agents on a given compute host then neutron fails to find the compute host root resource provider and therefore fails to create the agent providers and the device providers.
Reproduction:
* deploy an all-in-one devstack with the minimum bandwidth configuration [1] and set [DEFAULT]/host for nova-compute and neutron agent to something else than the hostname of the compute host.
* start up the nova and neutron services
* check what resource providers are created during the startup
Expected:
