Description Lars Kellogg-Stedman 2013-11-10 02:34:42 UTC

Description of problem:

After creating a keypair in nova:

  $ nova keypair-add --pub-key id_rsa.pub test
  $ nova keypair-list
  +------+-------------------------------------------------+
  | Name | Fingerprint                                     |
  +------+-------------------------------------------------+
  | test | 8b:56:b0:3f:c8:ad:38:a6:94:f4:a7:26:83:75:cc:85 |
  +------+-------------------------------------------------+

The keypair-show command returns an error, rather than details about
the keypair:

  $ nova keypair-show test
  ERROR: can't set attribute

In /var/log/nova/api.log:

Comment 1 Kashyap Chamarthy 2013-12-24 10:43:55 UTC

Version: 

  $ rpm -q openstack-nova-api
  openstack-nova-api-2013.2-4.fc20.noarch


Confirmed:

  $ nova keypair-list
  +--------+-------------------------------------------------+
  | Name   | Fingerprint                                     |
  +--------+-------------------------------------------------+
  | oskey1 | c1:69:bd:43:07:bc:d4:47:06:21:28:a0:ef:e6:d1:0f |
  +--------+-------------------------------------------------+

  $ nova keypair-show oskey1
  ERROR: can't set attribute

  $ echo $?
  1
 

However - the HTTP status throws 200 in the log messages (for Lars, above it threw 404):
