Hum, ok but why ? I'm running essex out of the box packaged in Ubuntu
12.04. I didn't modify the code (except comment the raise line in cfg.py
for this problem), but I did a lot of reinstall, modify configuration,
drop nova db, etc.
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.

You have a circular import somewhere That is causing scheduler/driver.py to be

If I comment the portion of code that raise the error (in
_is_opt_registered(opts, opt) of cfg.py), I get the following error :
ClassNotFound: Class SimpleScheduler could not be found: cannot import name vnc
I have the same error if I replace --scheduler_driver by --scheduler_manager in
nova.conf.
novnc is not installed because it give a configure error, but nova-vncproxy is
well installed.
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 ?

Ben,
It is possible to have the option specified in a code. Try grep -r on whole
code.
Thanks,
Joseph

Hi Joseph,
Thank you for your answer. 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.

Ben

Ben,
As the error message suggests, it is due to a duplicated option of
scheduler_host_manager. It is specified more than once somewhere.
Thanks,
Joseph

Hi,
No idea for my scheduler problem ? 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 ?

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 ?
Thanks,
Ben
