This is true offcourse but that mostly depends upon the applications
within the domU and wheter or not you use swap space.

I've also "misused" the save-restore function alot by now insted of
rebooting the domU's in some occasions apart from snapshots.

But I think there definitly is use for such a function (especially
when considering backup possibilities and HA systems, which could use
a restore snapshot and not having to wait until the domU has booted
again)... but as with many of these risky things: put it away deeply
and put hunderds of warnings with it ;-)

and get's out of sync with the saved cpu-/memory-status.

This can cause a crash, data-corruption ...
