[Bug 1385468] [NEW] Cells assumes 1:1 compute-service:compute-node mapping

 

Public bug reported:

Cells capacity calculation seems to assume one compute_node per nova-
compute service. It calculates capacity data by service name,
overwriting the value for each compute_node. This results in the cell
only showing capacity for one compute_host for each nova-compute service
in the cell.

Observed running Ironic, where there are many compute_hosts in a nova-
compute service.

** Affects: nova
