To provide some background I was talking with @olivierlambert over on ddelnano's Discord about an issue I was having with the cloudinit options not showing up in XO on any templates I made with the XenServer packer.io builder made by ddelnano.

What im trying to do
Im trying to have packer run every month via a CI/CD pipeline to generate a golden vm template every month. My goal for the template is to have it "cloudinit ready" so I can use it in my Terraform configs to provision workload vm's. I also want Packer to use Ansible to install basic system monitoring utilities such as netdata and any other necessary packages for example the xe-guest-utilities.
Where I am right now
Right now I have got Packer working up to a degree, I can create the template completely fine. I have gotten Packer to run my ansible playbooks on the host and have also used the file provisioner and shell provisioner to test installing packages and moving files onto the template vm. Where I am stuck though is getting the cloudinit options to show up inside of XO. I have validated multiple times that my vm template has a disk attached to it and if I create a vm from the Packer generated template I get the options shown below
As you can see the disk from the template is there for sure under the name "Packer-disk" but I still get prompted to insert a iso/dvd instead of prompting me for a ssh key or cloudinit config which by my understanding it should show those feilds if there is a disk in the template which there is but thats obviously not working. If I continue and create the vm with the options as shown below it boots into a fully installed ubuntu 20.04 os and is configured just like it should be with the ansible playbooks, shell provisioner, and file provisioner taking affect and working perfectly. The issue is there is no cloudinit disk which leaves the cloudinit config in the os "broken" due to there being nothing for cloudinit's nocloud or configdrive datasource to read.
Troubleshooting
The first thing that I did to troubleshoot is I downloaded the Ubuntu 20.04 cloudimg ova file and imported it into XO through the VM import utility in the web console. I then immediately turned it into a template and tried to create a vm from that and that showed all of the cloudinit options as expected.
The template has a name label of "ubuntu-focal-20.04-cloudimg" and the template UUID is "d1d97fd9-4d01-39cb-f5b8-e34c3a97ccc8". I then wanted to compare the template parameters so I went and looked for my Packer generated template, it has a name label of "ubuntu-2004-server-golden-v2023.01" and a UUID of "422081e2-6b73-f642-fc82-6cba4313a9da". From there I then went out and got the following data that has been posted in the Debug Logs Section, a list of the template parameters, a list of vbd's attached to each template, a list of the vbd's parameters, and a list of the vdi parameters.
Ive only been using the XCP-NG and XO platform for about 5-6 months so I am sorry if there is somewhat obvious diagnostic data missing, let me know and im happy to gather any information needed to resolve this issue. From my limited knowledge this seems like its somehow related to XO not seeing the attached disk on the template or the Packer plugin not setting some parameters that are required for XO to see the attached disk when converting to a template. If anyone has any suggestions or any ways to help me out it would be very appreciated.
