Setting static network settings in the "Initial Run" section works fine when
deploying a VM from template. When using "Run" to start the VM, customization
works as expected. On a reboot the network settings are maintained however if the VM is
shutdown and restarted the settings are reverted to DHCP. When editing the VM the
cloud-init settings are still set and a visible in the "Initial Run" section.
cloud-init (0.7.9-24.el7.centos) - Previously 0.7.9-20.el7.centos but upgraded to see if
it would fix the issue.
oVirt engine (4.2.4.1-1.el7)
Guest OS (CentOS Linux release 7.4.1708)
There is another thread that reports exactly the same issue and behavior here: -
https://lists.ovirt.org/pipermail/users/2018-March/087860.html
Grateful for any thoughts or assistance.

New subject: cloud-init reverting static network settings to DHCP on shutdown and restart
I think that before a shutdown / restart the cloud-init configuration is attached as there
is /dev/sr1 visible. On shutdown / restart the config is no longer attached and there is
seemingly an error related to not being able to find the data source: -

I have the same issue since some months. Since cloud-init doesn't sees
any configuration, applies the default, which is to use dhcp.
I don't remember if it is a bug of cloud-init or a misconfiguration,
but now i solved removing cloud-init package after the first boot.
In case you want redeploying, you can keep cloud-init and disable its
work by disabling the service:
touch /etc/cloud/cloud-init.disabled

Hi Ryan,
This behaviour reproduces for me as well with
ovirt-engine-latest-nightly-snapshot,
cloud-init-0.7.9-24.el7.x86_64,
Centos-7.4.1708 VM.
Can you comment?
Thanks

New subject: cloud-init reverting static network settings to DHCP on shutdown and restart
Hi,
we made this solution for us:
We add a cloud-init script to the cloud image, before we add this to our templates.
In /etc/cloud/cloud.cfg.d/, we create a file 98_runcmd.cfg with the following content:
write_files:
- content: |
network: {config: disabled}
path: /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
permissions: '0700'
- content: |
#!/bin/bash
rm /etc/cloud/cloud.cfg.d/90_dpkg.cfg
path: /var/lib/cloud/scripts/per-boot/datasources.sh
permissions: '0700'
This should create the file /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg after
first cloud-init run and then network config is never touched again.
Without disabling cloud-init completely, you are able for example to set a root password
to login into VM console, when you have to debug something and can't login anymore to
ssh.
We have password logins disabled by default over ssh.
We also remove /etc/cloud/cloud.cfg.d/90_dpkg.cfg and set datasource_list to
["NoCloud", "ConfigDrive"] in /etc/cloud/cloud.cfg
-> VM will reboot with this a way faster. Without it, cloud-init will look for too much
different location to find a valid config.
