> Hi,

> With our oVirt 3.3, I created a snapshot 3 weeks ago on a VM I've
> properly shutdown.
> It ran so far.
> Today, after having shut it down properly, I'm trying to delete the
> snapshot and I get an error :
> 
> "Failed to delete snapshot 'blahblahbla' for VM 'myVM'."
> 
> The disk is thin provisionned, accessed via virtIO, nothing special.

> The log below comes from the manager.
