How we can configure the VM with additional software on boot in Openshift Virtualization

[smunirat]

Would it be possible to point to how we can configure the VM with additional software on boot , like some set of installations on start of the VM or run a set of commands

You can see an example on 7.4.2.3.4 -> https://docs.redhat.com/en/documentation/openshift_container_platform/4.15/html-single/virtualizatio...

- cloudInitNoCloud: 1

#cloud-config
runcmd:
- [ setsebool, -P, virt_qemu_ga_manage_ssh, on ]

- [ 'sh', '-c', '/bin/yourverylongcommandhere --options --whatever --force']

Add as many lines under "runcmd:" as you need with the specific commands to configure your instance. However, before getting too crazy you probably want to use something else like Ansible (or Ansible Automation Platform) to perform your operating system configuration, rather than something embedded into the VM creation process. 

In this step you want to configure the bare minimum to make your VM reachable on the net, and manageable by your existing tools (create users, inject SSH keys, configure networking, etc). Anything beyond that usually belongs to Ansible Automation Platform.
