Bug skimming
------------
The REST API of Nova only accepts IDs. The translation from instance 
name to instance ID happens in the "python-novaclient" CLI. 
The translation seems to have an issue with soft deleted instances.

** Also affects: python-novaclient
   Importance: Undecided
       Status: New

** Changed in: nova
       Status: New => Invalid

Title:
  'Nova restore <server>' accepts only ID of server, not its name

Status in OpenStack Compute (nova):
  Invalid
Status in python-novaclient:
  New

Bug description:
  For softly-deleted instance 'nova restore <server>' command returns:
  root@node-7:~# nova restore vm1
  ERROR (CommandError): No server with a name or ID of 'vm1' exists.

  Steps to reproduce:

  1. On every controller and compute add the
  reclaim_instance_interval=86400 line to [DEFAULT] section of
  /etc/nova/nova.conf

  2. Restart nova-api service on controllers and nova-compute service on
  computes

  3. Create net01: net01__subnet, 192.168.1.0/24:
  neutron net-create net01
  neutron subnet-create net01 192.168.1.0/24 --enable-dhcp --name net01__subnet

  4. Boot instance vm1 in net01:
  NET_ID=$(neutron net-list | grep 'net01' | awk '{print $2}')
  nova boot --flavor m1.micro --image TestVM --nic net-id=$NET_ID  --security-groups default vm1

  5. Create a volume and attach it to an instance vm1:
  cinder create 10 --display-name test-volume --availability-zone nova
  VM_ID=$(nova show vm1 | grep '| id ' | awk  '{print $4}')
  VOL_ID=$(cinder list | grep 'test-volume'| awk '{print $2}')
  nova volume-attach $VM_ID $VOL_ID /dev/vdb

  6. Delete instance vm1:
  nova delete vm1

  7. Check that instance vm1 is really in SOFT-DELETE state:
  root@node-7:~# curl -s -H "X-Auth-Token: $TOKEN" $NOVA_ENDPOINT/servers/395ae0d7-59d9-4475-876d-3da1d0acc430

  8. Try to restore the previously-deleted instance with its name as an argument:
  nova restore vm1
  The result is:
  ERROR (CommandError): No server with a name or ID of 'vm1' exists

  9. Try to restore the previously-deleted instance again with its  ID as an argument:
  nova restore 395ae0d7-59d9-4475-876d-3da1d0acc430
  The result is:
  root@node-7:~# nova list | grep vm1
  | 395ae0d7-59d9-4475-876d-3da1d0acc430 | vm1  | ACTIVE | -          | Running     | net01=192.168.1.43 |

  In total,
  Expected result: both name and ID of server are accepted and processed correctly by 'nova restore' command
  Actual result: only ID of server is accepted, not its name
