…zon VPC CNI On Ubuntu 24.04+, cloud-init network hotplug is enabled by default (cloud-init PR 4799). This causes cloud-init to reconfigure netplan when CNIs dynamically attach secondary ENIs, breaking BPF masquerade and network routing functionality. This fix disables cloud-init network hotplug by creating a configuration file at /etc/cloud/cloud.cfg.d/99-disable-network-hotplug.cfg that sets updates.network.when to only boot-new-instance, preventing cloud-init from handling hotplug events.
