Wrong ownership of template saved from instance

Product Support Operations
1

When saving a powered off virtual machine as template using a regular user, the resulting template is saved with oneadmin:oneadmin ownership, making it invisible to the original user.

No errors are reported otherwise, the saving process runs fine.

Versions of the related components and OS (frontend, hypervisors, VMs):

OpenNebula 7.0.1

Steps to reproduce:

  1. Instantiate a VM as a user not member of oneadmin group.
  2. Power it off.
  3. Save it as a template.

Current results:

Template is saved with oneadmin:oneadmin ownership, resulting in an unusable template invisible to the original user.

Thank you for the detailed issue behaviour.

  • Can you please share the permissions of the original template before being saved by the user?
  • Did this happen with Fireedge (GUI), with the CLI or with both?

Thank you

Hello Bruno,

the original template has oneadmin:oneadmin ownership. It was saved from another one which had my user as owner and got changed to oneadmin. I hadn’t noticed until now as my user belongs to oneadmin group.

Just tried to clone from the CLI and it works fine, the machine is saved with the ownership of the user that launches the command.

Some screenshots:

Thank you for your help.
