>From what I see the following storage drivers provides internal snapshots:

QCOW2 files
sheepdog
rbd
nexenta (not fully functional)

The problem with that is that most users use LVM, NFS or RAW files on local storage.
So how can we snapshot such images?

For NFS and RAW files we can create and external snapshot (base image + writable image file)?

But how can we handle LVM (lvm snapshots on shared storage does not work at all)?
