Hello there, when i try to restore a snapshot i got this error :

You might want to take a look at these two [1] [2] topics about this as well.
The short of it is: If you're using ZFS, you can only roll back to the last snapshot, but you can do this multiple times (or use CLI to do it all at once), but it will destroy all snapshots in-between, so no going back and forth. If you want(ed) to keep the different snapshots and be able to form a snapshot-tree, you'll have to use a different storage-type for the snapshots.

There are two ways, depending on if you wanna keep the snapshots or not.

If you don't want to keep the snapshots:
- Destroy all snapshots that come after the snapshot you wanna roll back to
- Roll back to that snapshot

I can't really recommend that, since if you make an error there is no way to go back.

If you wanna keep the snapshots:
- Clone the VM.
- Destroy all snapshots in that cloned VM, that come after the snapshot you wanna roll back to
- Roll back to that snapshot

If you wanna keep the snapshots:
- Clone the VM.
- Destroy all snapshots in that cloned VM, that come after the snapshot you wanna roll back to
- Roll back to that snapshot

But, the cloned VM do not include any old snapshots.

That is right. The probably nicer way would be to
- Clone the VM and select the Snapshot you want to roll back to
- Check your new VM
- Delete the old VM if you are 100% sure you don't need any snapshots anymore.

Hello,
"- Clone the VM and select the Snapshot you want to roll back to"
what's this mean ? select the Snapshot in what ? in the original VM or in the cloned new VM ?

When you clone a VM, you can select what state or what snapshot you want to clone.

Can only select the latest snapshot to clone.

If select the older snapshot, An error will occur:

Ahh so that does not work with ZFS.

Then only that works:

You can't keep the snapshots:
- Destroy all snapshots that come after the snapshot you wanna roll back to
- Roll back to that snapshot
