@jichenjc,

You're right the behaviour is as expected, because with current devstack
the service endpoint for nova comes up with
http://192.168.1.8/compute/v2.1 which obviously points directly to a
version.

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

Title:
  Discovery: GET "/" returns  single version instead of array of
  versions

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Currently the behaviour of nova API breaks standard practice of
  version discovery [1] and SDK consumers by returning a single
  "version" element instead of an array of "versions.
