  Well the problem is snapshotting the storage devices and doing this
as efficiently as possible.
  I admit that I do the
    1/ stop the domain
    2/ rsync -vP /xen/domain.img backup: /xen/domain.img 
 a bit too often to my taste and I would love something nicer, but at this
point we need better support at the hypervisor and integration with system
specific support. Not a piece of cake, and not something which can be
attacked just at the libvirt level.

  At the moment it's a bit out of reach unfortunately,

Daniel
