@bcatubig I've done all the magic but still my cloud init is not taken into account completely.
I can see the VM is created with 10 MB additional disk.
I can mount this device and see that it does contain my cloud-init script.
but the script is not executed and cloud-config logs don't contain any useful information.
Please advise what would be the right way to track this issue??

@moisei Can you list steps taken?

Can you verify that ConfigDrive is enabled in the dpkg-reconfigure of cloud-init?

I haven't experimented with a full cloud-config. Only injecting an SSH key via XOA. I'll run through the steps again tonight to see if I run into any issues.

@bcatubig yes ConfigDrive and only ConfigDrive is enabled. My script does 3 things: SSH, set hostname, and touch some file. None of them is executed and the cloud-init logs doesn't show any trace of the execution.

#cloud-init

hostname: {name}%

ssh_authorized_keys:
  - ssh-rsa AAAA...kd mykey@myhost

runcmd:
 - [ touch, "/tmp/CLOUD_INIT_WAS_HERE", / ]
 - touch /tmp/CLOUD_INIT_WAS_HERE_1
 - touch "/tmp/CLOUD_INIT_WAS_HERE_2"

@moisei Before rebooting the Ubuntu 18.04 vm to convert it to an image, did you enable cloud-init service by running

sudo systemctl enable cloud-init

before powering off the vm?

moisei

@bcatubig yes I did. I've just followed your instructions above. Also the fact the cloud-init logs are present indicates that it is running, isn't it?

bcatubig

@moisei Sure

Can you try running dpkg-reconfigure cloud-init and select both ConfigDrive and the Openstack option.

From there, I would try the vm template process again.

If that still fails, I would try manually invoking cloud-config from the new vm with the attached cloud-config drive to see if there is an issue with cloud-config or your config.

It should provision itself automatically if everything is correct.

If that fails, you may need to attempt the entire process again and do some more trial/error.

@bcatubig it didn't help. would you mind to share the config that is working for you?

bcatubig

@moisei I didn't use a custom cloud config. I've only tried adding the ssh-key via XOA

@bcatubig

I see this message on the console right after the VM is created. Could it be somehow helpful?
