Open Stack

Hi Brian,

Thanks for a really detailed response.
In light of that, I will discuss with my teams about moving openstack-helm in line with this.

Thanks,
Karl.

Yes, in the Ussuri cycle a large effort was made to move all the
networking-ovn code into the Neutron tree, instead of having it be an
out-of-tree driver [0].

And finally in the Yoga cycle it was made the default for devstack [1].

Since then the two major distros, Ubuntu and Red Hat, have made OVN the
default in their deployment tools, so going forward it is safe to assume
it will eventually be in the majority for installations.
