Hi,
not the direct answer to your question, but as you wrote about welcome
hints...

couldn't it be simpler to take one of the images officially provided by the
CentOS project and then use one of:

1) diskimage-builder
https://docs.openstack.org/diskimage-builder/latest/

2) guestfish / guestmount
https://docs.openstack.org/image-guide/modify-images.html

3) virt-customize
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-guest_virtual_machine_disk_access_with_offline_tools-using_virt_customize

Or do you have any particular needs?
Gianluca
