I am using cloud-init v19.1 where I am passing config drive from nova layer while VM deployment.
On a RHEL8 environment, I am observing IPv4 interfaces not coming up. We are setting NM_CONTROLLED = no in the interface files and since RHEL8 recommends to use NetworkManager to configure network and create connectivity it is failing.
we are setting NM_CONTROLLED = no using the code
    iface_defaults = tuple([
        ('ONBOOT', True),
        ('USERCTL', False),
        ('NM_CONTROLLED', False),
        ('BOOTPROTO', 'none'),
        ('STARTMODE', 'auto'),
    ])

under the file [1] . Due to which the Network Manager is not able to handle the interfaces

[1] cloudinit/net/sysconfig.py

Making ('NM_CONTROLLED', True) fixes the issue.
