Re: [Openstack] Unable to start nova-scheduler : duplicate option: scheduler_host_manager
I just encountered the same problem, when I added a decorator to a method but the decorator did not exist. Just putting it here as it took me quite a while to find this silly problem, hope it helps somebody. On Thu, Aug 23, 2012 at 12:10 AM, Ben wrote: > Hum, ok but why ?

Re: [Openstack] Unable to start nova-scheduler : duplicate option: scheduler_host_manager
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.

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 ?
