2. Status:
   1. CML-P 2.0 N/A
   2. CML-P 2.1 and refplat_p-20201020-fcs.iso not fixed

Ubuntu 18.04 LTS (Bionic) image has interface name like a enp0s2 and CML-P 2.0 Lab Manager shows enp0s2 respective. But, 20.04 LTS (Focal) image has interface name like a ens2 and CML-P 2.1 Dashboard display still enp0s2.

1. enp0s2 → ens2
2. enp0s3 → ens3

So, Ubuntu 18.04 LTS (Bionic) Netplan configuration not works on Ubuntu 20.04 LTS (Focal) because actual interface name is like a ens2 but not match enp0s2 that displayed on CML-P 2.1 Dashboard.

This problem cause IP network configuration not properly configured. ( Static IP, DNS, Static Routes, …,etc. )

1. Change your cloud-init cloud-config User-Data interface name to use ens2.
2. Use Ubuntu 18.04 LTS (Bionic) Image.

Essential part

# before
enp0s2:
   match:
      name: enp0s2
# after
ens2:
   match:
      name: ens2
