(The reason is pve-qm-image-format contains more than our storage layer
supports). But pve-storage-format is actually is also not fully correct,
because it contains "subvol", which should not be used for VM images. We
could think about adding a new in the storage layer (because that's
where it needs to be supported) that includes only the ones that can be
used for VM images.

Yes, that's what I mean by "fallback" :)
