No, no. Most OpenStack deployments are neutron based with ovs because its the default these days.
There are all sorts of warnings to folks for years saying if you start with nova-network, there will be pain for you later. Hopefully, that has scared away most new folks from doing it. Most of the existing folks are there because they started before Neutron was up to speed. Thats a different problem. So I would expect the number of folks needing to go from nova-network to neutron to be a small number of clouds, not a big number. Changing the defaults now to favor that small minority of clouds, seems like an odd choice. Really, I don't think finding the right solution to migrate those still using nova-network to neutron has anything to do with what the default out of the box experience for new clouds should be... Having linuxbridge be the default for folks moving from nova-network to neutron might make much more sense then saying everyone should by default get linuxbridge.

Having LB as the default seems like an odd choice. You also wouldn't want to change the default before LB is tested at the gate. Simple things need to be simple to accomplish, and defaults MUST be simple to use. LB's support requirements are very simple compared to OVS. This is an achievable first step away from nova-net and once conquered the second step becomes less overwhelming. Look at the success of swallowing the entire elephant at once that we've seen in the last $TOO_MANY years. dt -- Dean Troyer dtro...@gmail.com<mailto:dtro...@gmail.com>
