What would cause this circular import ? Can I tweak the code to avoid this circular import (as workaround to validate this hypothesis) ?
Thanks to all for your help. Ben Le 22/08/2012 18:00, Vishvananda Ishaya a écrit :
You have a circular import somewhere That is causing scheduler/driver.py to be imported twice.

I suspect the error raised is not the original error, only side effect... I joined the trace of nova-scheduler before and after the code comment. What can I try now ?

Yes, but where could be that option ? It's not duplicated in my nova.conf file, and this is the file the nova-scheduler uses. My nova.conf file joined.

It was working at the beginning (I suppose because I could launch instances), but I did a lot of modification, modifying networks, deleting nova db, rebuild it, etc. Any idea on what I can do to identify the problem ? Where can I find the mentionned option except in nova.conf ? Ben Le 22/08/2012 00:46, Ben a écrit :Hi, I'm trying to setup a little nova cluster with 3 nodes : - 1 controller node running all services but compute - 2 compute nodes running compute and network only I have faced a lot of issues, but I can't understand this one. When I start nova-scheduler on controller node, the process dies instantly with this error : CRITICAL nova [-] duplicate option: scheduler_host_manager So I can't start an instance, it remains stuck in building state. I have checked my nova.conf file, and I only see this line : --scheduler_driver=nova.scheduler.simple.SimpleScheduler What does means this error, how can I solve it ?
