Also to me seems ok, is similar to the configuration we're using to deploy.

You mean cloud-init configuration-disk? no, the work is directly done
by oVirt. oVirt knows what you want to put into the configuration
drive and creates a new cdrom device with the configuration drive to
be attached directly to the vm during "Run Once". Once restarted with
standard "Run" the device disappears.

I simply run a task after first successful boot with cloud-init that runs

yum erase -y cloud-init

What do you mean grouping? via engine interface you can apply a tag to
them and then lookup by tag, select all and shutdown.


Or use Ansible 'with' or give all the VMs as the targets for the task.
