I have multiple PVE 5 and 6 clusters in my environment. I’ve tried to add my hosts using the compute resource menu, but I got a lot of error that are already here documented: https://github.com/theforeman/foreman_fog_proxmox/issues
It seems the integration is not in a clean working state.
I’m willing to help testing the integration with PVE to improve it. So please ping me if required.
