Title:
  nova hypervisor-list will generate exception

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Version: Liberty.
  OS: controller & compute node are ubuntu 14.04 server, follow the doc to install.

  After installed
  Using "nova host-list"
  will get the result correctly
  +------------------+-------------+----------+
  | host_name        | service     | zone     |
  +------------------+-------------+----------+
  | controller       | cert        | internal |
  | controller       | scheduler   | internal |
  | controller       | consoleauth | internal |
  | controller       | conductor   | internal |
  | compute-node-164 | compute     | nova     |
  +------------------+-------------+----------+

  but if use "nova hypervisor-list"

  ERROR (ClientException): Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
  <class 'nova.exception.ComputeHostNotFound'> (HTTP 500) (Request-ID: req-0649f773-8b50-4b84-a670-d8c290f77439)

  
  From the dashboard, in the System -> hypervisor panel, I can not find the hypervisor. when navigate to this page,  an error will display get not the hypervisor informatin.
  The compute node is displayed on "Compute Host" tab, not not in the Hypervisor tab.
