It's a off-topic question, but I just ask out of curiosity (don't know
much about LVM snapshots yet):

If I do a LVM snapshot of a running VM (or e.g. databases, too) and backup
it, what happens if I restore it later? The VDI was open while the backup
was done (and the information inside the VDI show this too, I guess). If I
start the VM after the restore, doesn't cause this problems? I guess
applications expect files with finalized written data (from the previous
shutdown) on startup.
