Hello There! So sadly, it is not that as it still show this error when I instantiate the template > Fri Apr 17 15:42:21 2015 [Z0][InM][D]: Host 172.18.10.8 (1) successfully monitored. > Fri Apr 17 15:42:23 2015 [Z0][VMM][D]: Message received: LOG I 10 Command execution fail: cat \<\< EOT | /var/tmp/one/vmm/kvm/deploy ‘/var/lib/one//datastores/100/10/deployment.0’ ‘172.18.10.8’ 10 172.18.10.8 > Fri Apr 17 15:42:23 2015 [Z0][VMM][D]: Message received: LOG I 10 error: Failed to create domain from /var/lib/one//datastores/100/10/deployment.0 > Fri Apr 17 15:42:23 2015 [Z0][VMM][D]: Message received: LOG I 10 error: internal error: process exited while connecting to monitor: qemu-system-x86\_64: -drive file=/var/lib/one//datastores/100/10/disk.0,if=none,id=drive-ide0-0-0,format=qcow2,cache=none: could not open disk image /var/lib/one//datastores/100/10/disk.0: Could not open ‘/var/lib/one//datastores/100/10/disk.0’: Is a directory 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 ☹ --- _[View the full topic](https://forum.opennebula.io/t/raw-vs-qcow2-images-vms-fail/607)._
