community.proxmox.proxmox_kvm not setting VLAN Tag on update

[mosespray]

Hello, I am trying to fully automate my disaster recovery solution for my Proxmox homelab.
I am using Proxmox Virtual Environment 9.1.9 and ansible [core 2.20.5]. I am also using the latest community.proxmox.promox library.

I have a set of Ansible playbooks and roles that use the various community proxmox roles to create vm_templates, clone them and create vms.

Everything seems to be working, so far, except...

My scripts successfully create a vm_template for ubuntu 24.04. It is configured with no VLAN and cloud-init (ipconfig (net0) ip=dhcp.

I have another script that:

• uses proxmox_kvm to clone the template
• uses proxmox_disk to resize the boot drive
• uses proxmox_kvm to modify the hardware and network settings

That 3rd script has this line:

net:
net0: "{{ create_proxmox_vm_containers_network_config }}"

The variable (create_proxmox_vm_containers_network_config) is set to "virtio,bridge=vmbr0,tag=100".

After the script finishes without errors, checking the Hardware line in the GUI shows the VLAN still set to nothing.

Even if I hardcode the line:
net:
net0: "virtio,bridge=vmbr0,tag=100"

Still no change.

To test that the role was actually doing anything, I hardcoded the name field to "test123" from what it was "naxr01".
That changed.

Finally, if I log into the Proxmox node and issue the following command:

qm set 2006 --net0 virtio,bridge=vmbr0,tag=100

It works.

I have tried looking at every possible log and used as much debugging as I could, but I can't figure this one out.

I even thought that I struck gold when I read this post, but I realized that I was already doing what was recomended.

If anyone has any insight or can offer any suggestions or help, I would really appreciate it.

Thank you in advance

Here is the relevant Ansible code:
