[Bug 1843947] [NEW] Horizon: Project->Compute->Overview does not reflect accurate VCPU usage, if a instance is shelved
Public bug reported:
The overview panel Project->Compute->Overview does not reflect accurate
resource usage, if a instance is shelved[1]. This is true as a admin or
normal user. The panel still shows shelved VMs using VCPU resources
To Reproduce:
=============
As a admin user in the admin project create several instances
$ openstack server list -c ID -c Name -c Status
+--------------------------------------+------------+--------+
| ID | Name | Status |
+--------------------------------------+------------+--------+
| c833339b-1782-4dac-8d95-27e67a6452a9 | advmtest-2 | ACTIVE |
| 60f4bc62-bdf1-4c21-983c-40b066fe7307 | advmtest-1 | ACTIVE |
+--------------------------------------+------------+--------+
and look at the VCPU used on that panel, ( VCPU used 2 0f 20 )
Hypervisor stats show 2 are in use too.
( Note: these are for 1 VCPU instances, Instance with more than 1 VCPU will be higher)
$ openstack hypervisor stats show | grep vcpus_used
| vcpus_used | 2 |
Shelve one of them, now check resources
$ openstack server shelve 60f4bc62-bdf1-4c21-983c-40b066fe7307
$ openstack server list -c ID -c Name -c Status
+--------------------------------------+------------+-------------------+
| ID | Name | Status |
+--------------------------------------+------------+-------------------+
| c833339b-1782-4dac-8d95-27e67a6452a9 | advmtest-2 | ACTIVE |
| 60f4bc62-bdf1-4c21-983c-40b066fe7307 | advmtest-1 | SHELVED_OFFLOADED |
+--------------------------------------+------------+-------------------+
$ openstack hypervisor stats show | grep vcpus_used
| vcpus_used | 1 |
Horizon Overview still shows ( VCPU used 2 0f 20 )
As the demo user
----------------
create 2 instances
$ openstack server list -c ID -c Name -c Status
+--------------------------------------+-------------+--------+
| ID | Name | Status |

Horizon Overview still shows ( VCPU used 2 0f 20 ).
If you try to view hypervisor stats as the demo user you encounter:
$ openstack hypervisor stats show
Policy doesn't allow os_compute_api:os-hypervisors to be performed.
As a non admin user you cannot run "openstack hypervisor" but as the admin user you can get a
accurate count of the number of VCPUs in use.
If this is not a bug then:
1) Should the overview be changed so that, when logged in as admin it show
VCPUS in use, and when a normal users opens the overview it shows # of instances created,
not necessarily how many VCPUS are active
2) Is it realistic to change policy.json so that users have access to this API
3) Is there a different way to count up VPCUs in use as a non admin user
[1] Shelve an instance - Shuts down the instance, and stores it together with associated data and resources (a snapshot is taken if not volume backed). Anything in memory is lost. ( https://docs.openstack.org/newton/user-guide/cli-stop-and-start-an-instance.html )
