New NICs in Instance Not Updated After Reboot

[bds-congnguyen]

Hi everyone,

I encountered an issue after adding additional NICs to an instance. Each time the instance reboots, the new NICs remain down. I attempted running cloud-init clean followed by a reboot, but it seems the new interfaces are not being updated in /etc/netplan/50-cloud-init.yaml, causing them to stay down.

Is there a way to automate this process or avoid manually editing the /etc/netplan configuration file? Ideally, we want to manage everything through Cloudstack, without needing to touch system files directly.

Thanks in advance for your help!

@bds-congnguyen I am assuming that the interface remains plugged into the instance after reboot. If you have configured the netplan with two interfaces it should get configured right.

yeah, but the 1st NIC Netplan configuration was generated by cloud-init. if we add another NICs into instance then it's should be setup automatically instead of add a Netplan manually. What do you think?

can you share the netplan file ?
