Thank you Carsten,
the absolute path to reservation.json file is working and now I have the
process running.
Bye,

Thank you Peter,
after changing the double quote (never trust of copy and paste... ), the
log shows another kind of error:

what it happens now?
try to specify the full path. Kea-DHCP tries to open the files based on the current
directory of the kea-dhcp4 process, which might be set to the file system root
("/").
<?include "/etc/kea/reservation.json"?>
should work.
Greetings
