Description of problem:
Testing kaminario cinder backend ,


[stack@cougar08 ~]$ cinder service-list

When trying to get service-list by host=hostgroup , only the first match returned and not all names start with hostgroup.

Example:
[stack@cougar08 ~]$ cinder service-list --host hostgroup
+------------------+-----------+------+---------+-------+----------------------------+-----------------+
| Binary           | Host      | Zone | Status  | State | Updated_at                 | Disabled Reason |
+------------------+-----------+------+---------+-------+----------------------------+-----------------+
| cinder-scheduler | hostgroup | nova | enabled | up    | 2017-02-02T04:43:22.000000 | -               |
+------------------+-----------+------+---------+-------+----------------------------+-----------------+

Hi Mike and Eric,

There is a RHOSP8 cert[1] blocked by this issue. If it is a known issue, is there any workaround to make the below test items pass?

o tempest.api.volume.admin.test_volume_services.VolumesServicesV1TestJSON.test_get_service_by_host_name
o tempest.api.volume.admin.test_volume_services.VolumesServicesV2TestJSON.test_get_service_by_host_name

Hi Eric, 

Could you help to confirm that whether this is a known issue of upstream? 
 I setup a rhosp8 machine,  run the test with the default cinder plugin, but I did not meet failure of these two tests:

o tempest.api.volume.admin.test_volume_services.VolumesServicesV1TestJSON.test_get_service_by_host_name
o tempest.api.volume.admin.test_volume_services.VolumesServicesV2TestJSON.test_get_service_by_host_name


Sincerely,
Jinhua Li

Hi  , 
I have managed to reproduce the issue on other setup , on Jinhua li setup.

I have decided to disable the first service in the list.

enabled it again .
