• Somehow the config doesnt seems to be working on avi-ci-t2
• Might try with a simpler user, like creating users!
• How do we bake cloud-init config into the image? So that we dont have to add it at the time of spawning new machine?

Re-run cloud-init config

cloud-init clean
cloud-init init

Latest working cloud-init file which should work for almost all scenarios:

        netfile=$(find /etc/network/interfaces.d -name "*.cfg")

runcmd:
-   [ "chmod", "u+x", "/script.sh"]
-   [ "/script.sh" ]

The script.sh script is responsible for network interface activation and is now working from OSM too.
