OpenStack Compute (nova)

No handlers could be found for logger "nova.root"

Asked by Philippe Berthault

The "nova-manage" command do nothing and systematically returns the following message:
No handlers could be found for logger "nova.root"

Nothing is written in the Nova database when I try to execute nova-manage db sync,
nova-manage user ..., nova-manage project create ... commands.

My configuration:
 - OpenStack Nova 2011.1 on a Fedora-14 x86_64 system.
 - Nova uses a MySQL database.

This is, I think, symptomatic of nova-manage not finding a configuration file. Could you try running nova-manage with the --flagfile option pointing to a nova.conf with a --sql_connection pointing to your MySQL setup...

If that doesn't work, could you give precisions on your setup ? How did you deploy nova on that Fedora box ?

This is a bug (vish is working on it) -- when an exception occurs before logging is setup, logging prints:

  No handlers could be found for logger "nova.root"

Hopefully his patch will help determine what the real issue is.
