RAW vs QCOW2 images; VMs fail

Hello There!

So sadly, it is not that as it still show this error when I instantiate the template

I tried instantiating one that I have in RAW format (thinking it might just not be the qcow2 which is the one making the trouble) and SUCCESS it can actually run… I don’t know what I’m missing. I installed the .deb provided by OpenNebula for this images, maybe is something that I’m missing installing or preparing for this images to work with OpenNebula?
Thank you in advance and sorry for making so much trouble :frowning:
