Are you sure about that? My OS complains that the disk is full. I can't
even start any VM anymore.
Looking at the file size isn't helpful. The 23 GB are the space that is

the number in the exact same way as qemu-img.

We have played a bit around with external snapshots (as suggested by
Eric Blake in post #3), however, it appears that external snapshots are
not fully supported yet. While I can create external snapshots, I'm
unable to revert to them using virt-manager (which we use for managing
our VM farm):

Regarding snapshot deletion, QEMU does punch holes into the image file
when deleting snapshots, so the space should effectively be freed, even
if this isn't visible in the file size. To get actually meaningful
numbers, you'd have to look at the allocated blocks rather than the file
size (e.g. by us

I don't have many commands handy, as we manage almost everything through
libvirt manager.
3) create a snapshot of the lined clone:
virsh snapshot-create-as --domain --name "test" --halt
4) revert the snapshot every X minutes / hours:
virsh destroy
virsh snapshot-revert --snapshotname test --r
