Re: [libvirt] [PATCH 1/2] (Updated & fixed) OpenNebula driver, libvirt-0.6.2



Hi,

Probably the easiest way to solve this is to get rid to of the
OpenNebula client library. So we do not have the license issue and, as
Daniel said, we do not have to include the C++ dependencies.

We'll try to send the patch ASAP.

Regards

Ruben
