<p class="MsoNormal" style="margin-bottom:12.0pt">+1 on need for this feature<br>
<br>
The way I've thought about this is we need a mode that stops the *automatic*<br>
scheduling of routers/dhcp-servers to specific hosts/agents, while allowing<br>
manual assignment of routers/dhcp-servers to those hosts/agents, and where<br>
any existing routers/dhcp-servers on those hosts continue to operate as normal.<br>
<br>
The maintenance use case was mentioned: I want to evacuate routers/dhcp-servers<br>
from a host before taking it down, and having the scheduler add new routers/dhcp<br>
while I'm evacuating the node is a) an annoyance, and b) causes a service blip<br>
when I have to right away move that new router/dhcp to another host.<br>
<br>
The other use case is adding a new host/agent into an existing environment.<br>
I want to be able to bring the new host/agent up and into the neutron config, but<br>
I don't want any of my customers' routers/dhcp-servers scheduled there until I've<br>
had a chance to assign some test routers/dhcp-servers and make sure the new server<br>
is properly configured and fully operational.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">These are all solid reasons for adding this, and it makes sense to me as well. From a deployers perspective, these would be a big win.<o:p></o:p></p>

<div>
<p class="MsoNormal">Given we have already filed a bug, hopefully we can get this addressed soon.<br>
<br>
Thanks,<br>
