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. VM successfully come up but removed the eth0 and loopback address config from /etc/network/interfaces file.... 6. Now from ifconfig it displays only eth1...becasue eth0 and loopback config removed by eth1..
