Hi Martin,

I created the VM through template...i have created OS template of ubuntu and debian with one nic....now when i deploy the VM through the template...it deployed successfully and i can pass the cloud-init data successfully....problem start when i add new nic...shutdown the VM and add new nic and push the cloud-init to configure this new nic(eth1)....the nic configured and VM will up but it will destroy the previous configurtion from the OS network config file (/etc/network/interfaces)...

To Reproduce :-

1. Create VM with one nic and run-once and push the cloud-init to configure the eth0

2. shutdown the VM.

3. add new nic

4. run-once and push the cloud-init to configure eth1

5. login to server with console and check through ifconfig...you will see eth1 only....

6. check the config file (/etc/network/interfaces)...you will find eth1 config only...

Thanks,

Punit

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?

Subject: [ovirt-users] Add new IP in ubuntu VM will clear the existing configuration | cloud-init

Hi,

I tired ubuntu 14.04 and debian 7.6....both has the same issue...

1. 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..

Thanks,
Punit
