Hi guys.
I update ower opennebula service from 4.12 to last vertion (4.14) and i decide change image datastore TM_MAD to qcow2 to using backing file ad speedup VMs deploy and migrate process.
But new VMs could not run, and i gain BOOT_FAILURE status with “Could not open backing file … Permission denied” error. I check backing image permissions but everything is OK.
