Public bug reported:

When I use nova cmd (nova usage-list),I get the CPU Hours 0.24,but I check the Overview page, the summary data is similar to this:
This Period's VCPU-Hours:0.12.

the nova --debug usage-list:
RESP BODY: {"tenant_usages": [{"total_memory_mb_usage": 62.18994346666666, "total_vcpus_usage": 0.24292946666666665, "start": "2014-12-08T06:25:30.623298", "tenant_id": "59f0edbed9b74743b66d645a11874739", "stop": "2015-01-05T06:25:30.927304", "server_usages": [{"instance_id": "e9412ae7-6809-4308-a9a3-9a1935004a58", "uptime": 428, "started_at": "2015-01-05T06:18:22.000000", "ended_at": null, "memory_mb": 512, "tenant_id": "59f0edbed9b74743b66d645a11874739", "state": "active", "hours": 0.12146473333333332, "vcpus": 2, "flavor": "2C512M", "local_gb": 0, "name": "demo"}], "total_hours": 0.12146473333333332, "total_local_gb_usage": 0.0}]}

Maybe the horizon usage summary vcpu-hours get the data from hours not
from total_vcpus_usage
