Remove everything out of tree, and leave only Neutron API framework as integration platform, would lower the attractions of the whole Openstack Project. Without a default "good enough" reference backend from community, customers have to depends on packagers to fully test all backends for them. Can we image nova without kvm, glance without swift? Cinder is weak because of default lvm backend, if in the future Ceph became the default it would be much better.
If the goal of this decomposition is eventually moving default reference driver out, and the in-tree OVS backend is an eyesore, then it's better to split the Neutron core with base repo and vendor repo. They only share common base API/DB model, each vendor can extend their API, DB model freely, using a shim proxy to delegate all the service logic to their backend controller. They can choose to keep out of tree, or in tree (vendor repo) with the previous policy that contribute code reviewing for their code being reviewed by other vendors. _______________________________________________ OpenStack-dev mailing list OpenStackemail@example.com http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
