<div>Yes, I found the same thing. (Please correct me if I am
wrong here.) </div>
<div>
<div><br>
</div>
<div>This was an original patch for the quantum-scheduler,
which is abandoned. </div>
<div>-> <a moz-do-not-send="true" href="https://review.openstack.org/#/c/18216/">https://review.openstack.org/#/c/18216/</a></div>
<div>One of the objectives was "Router to l3 agent is a many
to many relationship." </div>
<div>One more important one was "One L3 agent hosting a router
plays default role, other L3 agents hosting the same router
are in colocated mode." </div>
<div><br>
</div>
<div>These are merged patches for the quantum-scheduler. </div>
<div>

</div>
<div>Some objectives has been changed from the original one to
"Router to l3 agent is a many to one relationship" </div>
<div><br>
</div>
<div>In my understanding, with these changes in new
quantum-scheduler, it is impossible to simulate
nova-network's multi-host mode with quantum. </div>
<div>In other words, <a moz-do-not-send="true" href="https://blueprints.launchpad.net/quantum/+spec/quantum-multihost">https://blueprints.launchpad.net/quantum/+spec/quantum-multihost</a>
is still not fully implemented yet. </div>
<div><br>
</div>
<div>I would like to know if this "multi-host mode in quantum"
is being postponed or being abandoned. </div>
<div><br>
</div>
</div>
