I believe there was another instance of this bug happened in the past: http://dev.opennebula.org/issues/4624

History

#1 Updated by Ruben S. Montero about 3 years ago

  • Resolution set to worksforme
  • Affected Versions OpenNebula 4.14 added

The error message is from libvirt/qemu, it has nothing to do with opennebula. Maybe you need to restart the VM? You may even try to create the VM manually with the generated deployment file (i.e. login in the node and execute virsh create deployment.0)

#2 Updated by Gunwoo Gim about 3 years ago

It seems like OpenNebula LVM datastore mounts images in raw format

#3 Updated by Edouard Bourguignon about 3 years ago

Same bug here on OpenNebula 5.2. Add to convert the image to boot the VM again. This only happens on attached disks.

#4 Updated by Daejuan Jacobs over 2 years ago

This looks like it could be related #3705

I have the same issue on 5.2 regardless if the image is uploaded by me or from the marketplace to my ceph datastores.
