The "kernel" field in the model assertion does not accept a file path.
You have to specify the name of the snap (e.g. what you put in your
snapcraft.yaml name: field). Then you can provide the kernel snap via
the --extra-snaps parameter to ubuntu-image. ubuntu-image will then not
try to fetch the kernel snap from the store but take your local one.
Btw. there is upcoming documentation of this process at
