Hello! I would like to create CDROM with some personalization data for QEMU VM. I've installed windows and cloudbase init, service is running. If I understand it correctly, I should prepare ISO and and attach it as CDROM to VM. I try to add user-data and meta-data similar to cloud-init and this attempt failed. I want to execute arbitrary commands and add ssh keys. Could you please provide me examples of ISO contents?

This is an example of an ISO with one user data script for PowerShell:

More info on the format of the user data scripts can be found here:

Let me know other scenarios that you would like to know about.

Thank you! Your example helped me a lot! But there is still a problem with multipart/mixed user data. I walked up through sources and currently it's not implemented. Can you please tell me how to combine cloud-config data with scripts execution?

Hi Adrian,

I am also facing the same issue with cloudbase-init...i installed windows and cloudbase-init in it but when i try to put some data from cloud-init metadata.json and userdata file...the VM doesn't accept it and failed...

Would you mind to provide an example metadata.json file....also does it require this format under ISO "/openstack/latest/metadata.json" or just generate the simple iso with meta-data file and attach to vm ??

Hello, The format is a convention cloudbase-init or cloud-init requires. You can start from the example ISO I provided before. Thanks.
