OpenNebula 4.0 is around the corner and we wanted to give you a sneak peek on one of the upcoming new features: Ceph integration.

The new Ceph datastore driver will be initially available for libvirt/kvm, the support for Xen will come in subsequent versions. Users will be able to use it really easily, by using the standard OpenNebula workflow:

1. Create a new image in the Ceph datastore,
2. create a template using that image,
3. and run the virtual machine!.

This driver uses libvirt to handle RBD devices (Ceph block devices) so simplifying a lot the Datatores and Transfer Manager drivers.

We would like to thank Grzegorz Kocur, Bill Campbell and Vladislav Gorbunov for their community contributions to develop this driver.

More about this in the OpenNebula Ceph Datastore documentation.

This new feature is ready to be tested in the ‘master’ branch.

Give it a try if you want!
