Hello everyone,
I’m encountering an issue when trying to restore a VM after a backup. I successfully created a backup action for a VM and saved it to a datastore of type “Backup.” However, when I use the “restore” feature in Sunstone, it creates a new image and a corresponding template but does not create the VM. I then attempt to create a VM from that template, VM is running but when I use VNC, the VM reports an error: “No bootable devices.” I have kept all the default settings and haven’t made any additional configuration changes. After that, I used rsync to transfer the backup image to the frontend, created an image from it, and manually created a template, which worked fine.
What should I do to make the OpenNebula restore feature work as intended?
Note: The backup has a size of 11.3GB (show in Sunstone). When using the ‘rbd info’ command, the manually created image has a size of 12GB, while the image created by Sunstone’s restore is 11GB.
Thank you.
**Versions of the related components and OS (frontend, hypervisors, VMs): Frontend: Ubuntu 22.04 - Opennebula CE 6.6 , KVM node, VM run CentOS. Use Ceph rbd for VM image.
Steps to reproduce: Restore a VM from it’s backup image through the Sunstone interface.
Current results: I had to manually create an image and template to restore the VM from its backup
Expected results: I can restore VM through the Sunstone and it run OK.
