It's playing clever tricks with snapshots.

The documentation is all there, it mentions how to associate a snapshot
with an existing VM. In the VDI context this is all pretty
straightforward with the information on a separate storage server, but
that's all ifs and buts in the generic context. There are lots of
pitfalls, and having a generic description of the manual would add many
pages of which most readers won't understand a word.
