Hi Punit, at which phase do you put operating system(OS) in this machine? You have installed VM with OS and the you use run once + cloud init (without reinstalling OS)? Just o be sure by adding extra IP (step 3) you mean new adding new network card (aka vNIC) to the VM, right?

Create VM with one NIC "eth0"...then run once and insert the cloud-init data and make it up... 2. Powerdown the VM. 3. Add extra ip "eth1"... 4. run once and insert the cloud-init data and make it up... 5.
