Public bug reported:

During the spawn process the rollback portion of the create_vm_record
step is supposed to detach volumes, destroy the VBDs, and then purge the
SR.  But this process relies on looking up VBDs attached to the
instance.  If the spawn process fails while creating/resizing a VDI then
there's no VBD to lookup and the SR and VDI will be left on the
hypervisor as orphans.
