Open Stack

Hi All; Im getting following error when trying to: following keystone
commands. What could be the problem?



#keystone role-list
No handlers could be found for logger "keystoneclient.v2_0.client"
Invalid OpenStack Identity credentials.


#But keystone service-list
No handlers could be found for logger "keystoneclient.v2_0.client"

nova commands also works.

# nova list

troubleshoot.
