VM provisioned with a blank drive

[rsauber-ot]

Describe the bug
Creating a VM from template results in a blank drive.

The template was made with the following steps:

packer to customize a cloud image, saving as a qcow2 image
curl using the API to upload the image:

curl -k -X POST "https://$PROXMOX_HOST:8006/api2/json/nodes/$NODE_NAME/storage/$STORAGE/upload" \
  -H "Cookie: PVEAuthCookie=$ticket" \
  -H "CSRFPreventionToken: $csrf_token" \
  -F "content=iso" \
  -F "filename=@$FILE_PATH" \

curl using API to create new VM:

curl -k -X POST "https://$PROXMOX_HOST:8006/api2/json/nodes/$NODE_NAME/qemu" \
  -H "Cookie: PVEAuthCookie=$ticket" \
  -H "CSRFPreventionToken: $csrf_token" \
  --data-urlencode net0="virtio,bridge=vmbr0" \
  --data vmid=9001 \
  --data cores=2 \
  --data-urlencode name=packer-ubuntu20 \
  --data-urlencode virtio0=packer-images:0,import-from=/data-zfs/packer-images/template/iso/packer-ubuntu-20.04.img \
  --data memory=4096 \
  --data agent=1

curl using API to convert to template:

curl -v -k -X POST "https://$PROXMOX_HOST:8006/api2/json/nodes/$NODE_NAME/qemu/9001/template" \
-H "Cookie: PVEAuthCookie=$ticket" \
-H "CSRFPreventionToken: $csrf_token" \

Software:

Foreman 3.9.3
Foreman_fog_proxmox 0.16.3

To Reproduce
Steps to reproduce the behavior:

1. click on hosts->create hosts
2. Host: Set Organization, Location, and Deploy On proxmox host.
3. Virtual machine: Leave everything default.
4. Operating system: Set Arch to x86_64, OS to appropriate OS, Provisioning method => Image Based
5. Interfaces: Set domain, subnet, and receive an IP
6. Click Submit and be excited it worked
7. Check console of VM only to be confused as to why it can't find a boot device

Expected behavior
Server spins up in Proxmox and the disk is based on/cloned from selected image.

• OS: macOS Sonoma 14.7.1
• Browser Chrome
• Version 131.0.6778.86

Additional context
If I clone the template inside of Proxmox it behaves as expected. I attached a recovery cd to the VM and found the drive was blank, no partitions, no data.

I feel like I am missing something and this should work.
