Bug Description

It seems to be intended, that CONF.libvirt.snapshot_image_format defaults to the format of the source image.
That is also what the docs say. See for example https://docs.openstack.org/nova/latest/configuration/sample-config.html

If the format of the source image is raw, the raw image is only used as a backing file with a qcow2 overlay. So find_disk() from nova's libvirt utils will return the overlay file and qcow2 as a format.

What we want to use here is the format of the backing file.
