How to Change Settings After Clone Debian 10 With Cloudinit Enable on Proxmox VE

Issue

I found an issue about create a linux vm as a template with cloudinit enabled. Seem like after cloned the virtual machine, the cloud-init cd rom didn’t be created automatically. We need to delete it,then change setings again to apply the apt source.
