Everything seems to work fine but there is still some issues that disturbs me<br>
<br></div>(1) nova logs:<br>In a productive deployment, as I did before, I can freely read the logs from "/var/log/nova". However, it seems that in devstack, I can only use the SYSLOG configuration to gather the logs. However, the logs of 8 machine is too large to handle and I want to read specificly the nova-scheduler logs. <br>
</div>How can I make it log to "/var/log/nova" as before?<br><br></div>(2) compute-scheduler choices<br></div>What I really want to do in nova is to add some new features by modifying the compute-scheduler. So I need to modify "compute_scheduler_driver" in "/etc/nova/nova.conf" and use a new scheduler class. But how can I do this via devstack? I tried to add "SCHEDULER=~~" in "devstack/localrc" but it didn't work. Anyone have any idea on that?<br>
<br></div>(3) use the modified /etc/nova/nova.conf<br></div>After I changes some configurations in nova.conf, the services need to be restarted to use the configs. But the only way to do so (as far as I'm concerned) is to ./unstack.sh + ./stack.sh, which will overwrite all the previous changes in "nova.conf". Is there any way that I can stop a certain service and then start it over to use the new configurations. <br>
<br></div>thanks <br><br></div>Eric Yao<br></div>
