zfs snapshot is a storage snapshot and qm snapshot is a Qemu VM state snapshot.
Both are storage snapshots but qm create a persistent state at creation time.
Also, you have the capability to save the current memory image in the snapshot.

What do you mean with "persistent state" ?
In some case, qm snap cron jobs fails for qm lock state, instead same cron using zfs snap have no truble ..
Do you know why ?

Thanks!
