I've seen some of the cool stuff coming with OVN and even a co-worker has done some great things with it.  However I was wondering if anyone had experience with Cumulus as the external provider for networks.  
It's just a "weekend project" I'm picking up and thought to ask on the list.  I've not found other posts on it yet but will continue to look.
I've just made a fresh lab with the latest and greatest oVirt on CentOS 7. 
Thanks to all and a happy holiday season ( if you're into the holiday thing ).
