Here you have, as promised a few days ago, the Beta of the upcoming OpenNebula 6.6! 
Among other features, “Electra” comes with:
- A fully revamped Backup solution, based on datastore backends, and a new type of image to represent datastores.
- An exciting integration with Prometheus, for the optimal observability of an OpenNebula cloud.
OpenNebula 6.6 is named after the Electra Nebula, the reflection dust cloud (coded “vdB 20”) associated with the Electra star, a blue-white giant star in the constellation of Taurus and the third-brightest star in the Pleiades cluster.
Many thanks in advance for your help testing this Beta!!
