Hey there,
unfortnunately /var/log/one/oned.log is giving me no further information. I’ve followed your tip with the empty disk imageand additionally tried to import an image of an existing plain file.into the file datastore. That worked. Both were like 2 GB large, which is larger than my intended os image. This is really weird. Could OpenNebula or KVM have a problem with the fact, that I am trying to run a VM inside another VM. Im mean, I am not running the frontend neither the host on a dedicated physical machine…
thx
