You need an extra disk, something like that under devices:

  agent:
    type: disk
    source: agent:config

thank you
Isn’t that should be out-of-box by Incus (or UI)?

I thinking of create PR to fix that issue in LXD UI but I don’t think they will accept it because it specific for Incus only

It only applies to specific versions of specific images, the vast majority of our images do not need the extra drive. In general Incus has a policy of treating images as untrusted so we don’t ever want a property of an image to cause automatic changes to instance configuration, which is why we instead have it report an error message and let the user perform the change if they believe it’s correct to do.

how I can determine if the image need it or not?

The image will have a restriction for cdrom_agent set in its properties.
