During the Neutron Newton-rc1 development cycle, a number of DVR-related issues have been fixed. Two of them were related to the SNAT.

You should consider re-enabling the DVR-HA since it is a critical piece and until Mitaka this was the major DVR's drawback.

Please note that it can still be enabled by setting EnableL3HA to true in Newton. There isn't really anything that prevents a user from doing so. The THT logic for handling enabling L3 HA if the controller count > 1 was added in newton to address backwards compatibility concerns as that logic has been moved out of the tripleo client. We will be revisiting how tripleo addresses HA configuration for neutron in Ocata. Whether L3 HA, DVR or otherwise will be enabled by default is yet to be decided.
