Title:
  Swapping a volume cause an exception

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Hi,

  Apparently, when cinder tells nova to swap the volume a of VM after a
  retyping it, this exception appears in the logs and the volume is not
  swapped. It seems the instance UUID is passed as parameter instead of
  a dict.

  
  I'm using last kilo packaged version for ubuntu 14.014 :

  To reproduce this, just create a volume, retype it while the VM is
  running and wait for the exception.
