[Users] Ovirt 3.3 - How to write a network plugin

Hello, I've seen ovirt can support plugin ... so is there any documentation about writing a plugin ? Can we write it in python ? Well because, here, we don't want to install openstack/neutron for network management ... It's too complicated and to heavy. I, your opinion wrong design choice about openvswitch implementation. Thank you in advance. Regards, -- -- Benoit
