For VMs this already happens.
When adding volumes to templates no such conversion to
base images happens yet (affects both VM/LXC). Because
templates are more-or-less supposed to be read-only it
probably makes sense to disallow adding volumes altogether.
Or should we bother and do conversion instead?
When a volume with linked clones is moved with 'delete source'
then the volume will be copied over and the source volume does
not get deleted, but the source volume disappears from the config.
With the second patch it gets added as an unused volume instead.
