MOC use case I think depends on this. I'll see if I can get someone
from there to respond.<br>

<p>Hi All,<br>
<br>
<br>
Right now, we found that nova.conf have many places for
region_name configuration. Check below:<br>
<br>
nova.conf<br>
<br>
*******<br>
[cinder]<br>
os_region_name = ***<br>
<br>
[neutron]<br>
region_name= ***<br>
<br>
<br>
<br>
*******<br>
<br>
<br>
From some mult-region environments observation, those
two regions would always config same value. <br>
<b>Question 1: Does nova support config different
regions in nova.conf ? Like below</b><br>
<br>
[cinder]<br>
<br>
os_region_name = <font color="#0000FF">RegionOne</font><br>
<br>
[neutron]<br>
region_name=<font color="#0020C2"> RegionTwo</font><br>
<br>
<br>
From Keystone point, I suspect those regions can access
from each other.<br>
<br>
<br>
<b>Question 2: If all need to config with same value,
why we not use single region_name in nova.conf ?</b>
(instead of create many region_name in same file ) <br>
<br>
Is it just for code maintenance or else consideration ?<br>
<br>
<br>
<br>
Could nova and keystone community members help this
question ? <br>
<br>
<br>
Thanks<br>
<br>
<br>
Best Wishes,<br>
