Code review comment for lp:~chad.smith/vmbuilder/jenkins_kvm_azure_netplan_hotplug

What happens when you remove the original eth0 and replace it? Does the boot happen promptly, or does it stall on the 50-cloud-init.yaml interface?

Would it be simpler just to suppress the original cloud-init netplan config?

Apart from that I think it looks fine, but I'm not an expert on how these things are built.
