 Hi list,
 
 I've been looking around the web for QinQ support in Ovirt. I see =

 Is QinQ still a future fea=

I'm afraid we do not support QinQ, and it's no=

roadmap.

However, we would love to under=

?)

I believe you can use network custom properties and
befo=
re/after_network_setup
hookpoint in order to tinker with this
yourself.

Regards,Dan.
