Cloud init - Each boot => New instance first boot

[smutel]

Hello,

Each time I reboot a vm with cloud init in proxmox, cloud init is started as the fist time (init). In the log we can see :

2022-12-01 09:42:03,763 - __init__.py[DEBUG]: Update datasource metadata and network config due to events: New instance first boot
2022-12-01 09:44:47,808 - __init__.py[DEBUG]: Update datasource metadata and network config due to events: New instance first boot
2022-12-01 10:01:39,166 - __init__.py[DEBUG]: Update datasource metadata and network config due to events: New instance first boot
2023-01-02 09:37:24,040 - __init__.py[DEBUG]: Update datasource metadata and network config due to events: New instance first boot
2023-01-10 08:29:49,835 - __init__.py[DEBUG]: Update datasource metadata and network config due to events: New instance first boot

I don't have this behavior in other cloud with the same image. Something to activate in proxmox or in cloud init ?

Thanks.
