[PVE-User] Snapshot with vzdump including RAM.

For applications running on the virtual machine as SQL etc "usually not a problem" is not good enough for me.
If you have transactions that haven't been committed in ram and you "cut the power" you're in a world of hurt.
Then again, backup of these services should be handled by the guest and not the host.

It's not useless, it would be the same as if the server had a hard reset at the moment of the snapshot (electric shortage for example) so datas will be consistent but daemons might not like it (database server might have to do a crash recovery at start for example but its usually not a problem as files wont be corrupted at FS level).
