Newly added network interface is not configured at OS level
You encounter a problem when you add a network interface post virtual machine deployment.
Problem
When a network interface is added, the changes are reflected in the GUI but not at the OS level network configuration on the virtual machine.
Explanation
The issue occurs because cloud-init does not automatically configure network at OS level post virtual machine deployment.
Resolution
To resolve the issue, manually configure the newly added network interface at OS level on the virtual machine.
