The deployment of the OVA results in an endless reboot loop

Question

I wanted to provide some context: I'm using Packer to build an OVA file from an ISO in order to deploy a virtual machine in VCenter. However, I'm encountering an issue where the deployment leads to an endless reboot loop. Interestingly, deploying only the ISO works without any problems.

Could there be something missing in my Packer code? Any insights would be greatly appreciated. Thank you for your help and time
