Hi,
I tough 'revisions_to_keep' was default to 3. I created a new pool
yesterday and specify 3 when creating it, but then a VM that I moved
to there had 1. (I discovered it after trying to restore config
because it doesn't boot fine).
Then I started to look at all other VM's and all private volumes have
1 'revisions_to_keep', also they had 'save_on_stop'. So I think this
is not very useful, when you halt the vm your are overwriting the only
snapshot you have.
Does delay 'save_on_start' too much?
Maybe this is due I started with some RC and then upgraded to
current-testing.

Actually, revisions_to_keep is about previous revisions. So "1" means

you have one snapshot you can revert to (the state before you've started
the VM).

default value is 1.

But was (and will be) this snapshot saved when you shutdown the VM?

Imagine you accidentally delete an important file, how can you use the
snapshot for recover it? Doing revert with the VM running? If you
shutdown the VM the snapshot with the important file will be lost.

I think it replaces the snapshot with a new one at VM start, not shutdown.

So if you delete a file, shutdown the VM, then revert immediately, you'll
be OK.

Oh yes! I've tested and worked fine.
