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 | +--------------------------------------+-------------+--------+ | 8713c7af-d0f0-4ae7-bcb8-07576f95b09b | demo-test-2 | ACTIVE | | 4f1cd938-c084-4466-bec8-9a4f78d123a0 | demo-test-1 | ACTIVE | +--------------------------------------+-------------+--------+ $ openstack server shelve 4f1cd938-c084-4466-bec8-9a4f78d123a0 $ openstack server list -c ID -c Name -c Status +--------------------------------------+-------------+-------------------+ | ID | Name | Status | +--------------------------------------+-------------+-------------------+ | 8713c7af-d0f0-4ae7-bcb8-07576f95b09b | demo-test-2 | ACTIVE | | 4f1cd938-c084-4466-bec8-9a4f78d123a0 | demo-test-1 | SHELVED_OFFLOADED | +--------------------------------------+-------------+-------------------+ 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.
