GATEWAY doesn't render VMWare

[John Jelinek]

cloud-init isn't rendered GATEWAY in /etc/sysconfig/network-scripts/ifcfg-eth0 with VMWare:
```
# Created by cloud-init on instance boot automatically, do not edit.
#

IPADDR=172.20.14.192
NETMASK=255.255.255.0
NM_CONTROLLED=no
ONBOOT=yes

USERCTL=no
```

Here's the default amazon-linux2 cloud.cfg:
```

Hi,

Thanks for filing a bug and attaching the logs.

Looking at the logs, it appears that the image has some modifications: namely, something created /etc/udev/rules.d/70-persistent-net.rules as a _directory_; which it is typically a file that cloud-init writes data. This is the traceback in the logs:

Can you see if your image before booting includes that path as a directory and remove that and try again?

[John Jelinek (john-z)]

I rebuilt, removing the directory you mentioned and got new logs. I've printed the cloud-init-output.log and attached the cloud-init.log:

I wasn't entirely clear in the last post: the problem still persists after addressing your recommendation.

[Ryan Harper (raharper)]

I think I see the problem, in your IMC config, you have one nic, but have not set it as primary:

config_file.py[INFO]: Parsing the config file /var/run/vmware-imc/cust.cfg.
config_file.py[DEBUG]: FOUND CATEGORY = 'NETWORK'
config_file.py[DEBUG]: ADDED KEY-VAL :: 'NETWORK|NETWORKING' = 'yes'

Can you add under the [NIC1] section

PRIMARY = true ?
