[libvirt] [PATCH RFC] Remove the Open Nebula driver

[Ruben S. Montero]

Hi,

Thanks for the headup. We totally agree with the reasoning in the
thread. In fact, the last version of OpenNebula is not compatible with
the libvirt driver. We planned to propose the removal of the
OpenNebula driver, and focus our efforts in the DeltaCloud adapter. So
please go ahead and remove the OpenNebula driver.

Best Regards

Ruben
