Description
===========
The error message from the following command contains a variable name ("instance_id") instead of it's value, it happens when trying to get a vnc console of instance in error status:

nova get-vnc-console 7d770210-d38d-45ac-9081-81afbb42d07d novnc

Error:

ERROR: Instance %(instance_id)s is not ready (HTTP 409) (Request-ID:
req-1edc01b8-3c78-4e98-8229-a0d07271e464)

Expected result
===============
The "instance_id" parameter should be converted to the actual instance uuid.

Reproduction
============
It reproduces when the instance is for instance in error status, a reproduction can be achieved using the following command on all-in-one deployment:

/etc/init.d/openstack-nova-compute stop ; nova get-vnc-console $(nova
boot --flavor 2 --image $(nova image-list | grep ACTIVE | head -1 | cut
-d" " -f 2,4) | awk '/\ id\ / {print $4}') novnc ; /etc/init.d
/openstack-nova-compute start
