Public bug reported:

Description
===========

In nova api reference [1], we know that we can list instances by status
or vm_state, note that vm_state should work for admin only. But
actually, listing instances by vm_state does not work as excepted in
queens 17.0.3. I checked the master branch, it should have the same
issue.

I added some logs and did the following tests：

* searching by status:

curl -g -i -X GET
http://<url>:<port>/v2.1/servers/detail?status=SOFT_DELETED

the logs:

Searching by: {'deleted': False, 'vm_state': ['soft-delete'], 'project_id': u'ddc5e1deb69b4b0a83a9cad2ba6dd4c6'} get_all /usr/lib/python2.7/site-packages/nova/compute/api.py:2384
Filters are {'deleted': False, 'vm_state': ['soft-delete'], 'project_id': u'ddc5e1deb69b4b0a83a9cad2ba6dd4c6'} get_all /usr/lib/python2.7/site-packages/nova/compute/api.py:2494

* searching by vm_state:

curl -g -i -X GET
http://<url>:<port>/v2.1/servers/detail?vm_state=DELETED

the logs:

Searching by: {'deleted': False, u'vm_state': u'DELETED', 'project_id': u'ddc5e1deb69b4b0a83a9cad2ba6dd4c6'} get_all /usr/lib/python2.7/site-packages/nova/compute/api.py:2384
Filters are {'deleted': False, u'vm_state': u'DELETED', 'project_id': u'ddc5e1deb69b4b0a83a9cad2ba6dd4c6'} get_all /usr/lib/python2.7/site-packages/nova/compute/api.py:2494


As you can see, nova does not process search option 'vm_state' the same way as search option 'status'.
