Public bug reported:
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.
