OpenNebula 4.14 is out, and it comes with lots of big and small improvements. In this post we want to showcase a brand new feature you may have missed from the release notes: disk snapshotting capabilities.
Now VM disks can be reverted to a previous state at any given time, and they are preserved in the image if it is persistent in the image datastore. For instance, you can attach a disk to a VM, create a snapshot, detach it and attach it to a new VM, and revert to a previous state.
The following video contains a quick demo, check it out!
