Dynamic Hostname Contextualization concern

Hi, I’m trying to setup contextualization for 15-hostname, but can’t seem to make it work.
I have the contextualization installed and is working fine because I tested it with the automated IP.

I’ve also ensured that the hostname and IP are already saved in the DNS server.

Is there anything else I should update or check for the hostname to be dynamically saved in the new VMs deployed. Thank you.

CONTEXT = “true”,
DISK_ID = “1”,
ETH0_IP = “”,
ETH0_MAC = “02:00:ac:16:50:0b”,
IMAGE = “Context”,
SET_HOSTNAME = “$name”,
