Libvirt doesn't reliably know the location of the backing chain when pre-creating images for non-shared migration. This isn't a problem for full copy, but incremental copy requires the information.

Forbid pre-creating the image in cases where incremental migration is required. This limitation can perhaps be lifted once libvirt will fully support loading of backing chain information from the XML.
