Title:
  Attribute error on virtual_size

Status in OpenStack Dashboard (Horizon):
  Fix Released
Status in OpenStack Dashboard (Horizon) kilo series:
  Fix Released

Bug description:
  Version: stable/kilo
  Run with ./run_test.py --runserver

  Running an old havana glance backend will result in an AttributeError
  since the attribute is introduced with the icehouse release. See error
  log at bottom of message. A simple check for the attribute will solve
  this issue and restore compatibility.

  Attached is a patch as proposal.

  Regards
  Christoph
