so if you're trying to use the community.general.proxmox plugin:
first, install it:
ansible-galaxy collection install community.general
[inventory]
enable_plugins = community.general.proxmox
and getting an empty resultset back (or just the promox node itself), you probably need to update the user to have full access.
Assuming you've created a user named "anisble" in the "pve" realm through the UI, do this on your Proxmox server:
pveum aclmod / -user ansible@pve -role PVEAdmin
By default that user can't do anything other than log in, and needs that role in order to enumerate everything.
Once you've done that, and created a <something>.proxmox.yaml file that looks like:
plugin: community.general.proxmox
want_facts: no
url: https://proxmox.local:8006/
user: ansible@pve
password: secretwords_ssh
validate_certs: no
you should be able to invoke ansible-inventory like so:
ansible-inventory -i <something>.proxmox.yaml --graph
