Of course that would be ideal but with NFV it may be more involved. This is similar Linux and TEM adaption around 04/05. We wanted to adapt Linux but it lacked required features that's when CGL specifications came into play to provide guidance a lot of features (TIPC, OpenIMPI, preempt_rt, AEM) lived outside mainline, supported by OS vendors delivering CGL compliant distro, while others decided to stick with IT, penetrating some applications like HLR. With NFV a likely scenario may evolve, TEMs need to start demonstrating to operators fixed and wireless virtualization use cases. The only significant difference is that unlike CGL for Linux, KVM has nor real representation and understanding of NFV reqs (as opposed to proprietary vendors). I can't speak for all TEMs but it's likely they will go off on their own to demo/proto-type and worry about Open Source acceptance later. > > -Christoffer > -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
