Public bug reported:

AWS EC2 - No network config specified on this AMI by default

Launching new suse-sles-12-sp3-v20171107-hvm-ssd-x86_64 (ami-518b2628)
within a private subnet (ie no public IP allocation) AMI located in
Region eu-west-1, results in the network config script for eth0 being
set to manual start:

BOOTPROTO=dhcp
MTU=9000
REMOTE_IPADDR=
STARTMODE=manual
CLOUD_NETCONFIG_MANAGE=yes
USERCONTROL=no
ETHTOOL_OPTIONS=

Network will start on the first launch but fail on subsequent restarts
or stop and starts since the script is set to manual. This only happens
when the instance is launched without a public IP (within a private
subnet).

Output of cloud-init.log where config is applied:

2017-11-19 05:57:29,742 - stages.py[INFO]: Applying network configuration from ds bringup=True: {'version': 1, 'config': [{'subnets': [], 'type': 'physical', 'name': 'eth0', 'mac_address': '06:9d:49:56:d4:d8'}]}
iface eth0 inet manual
 into {'lo': {'auto': True, 'ipv6': {}}, 'eth0': {'ipv6': {}}}

Also noticed the following error in the cloud-init-output.log:

2017-11-19 06:44:32,421 - __init__.py[WARNING]: apply_network_config is
not currently implemented for distribution '<class
'cloudinit.distros.sles.Distro'>'.  Attempting to use apply_network

Downgraded cloud-init to version 7.9 on the instance and created a new
AMI, this works fine and the network script is set to STARTMODE=onboot,
also no error in cloud-init-output.log.
