I created an image with Diskimage-builder and installed python-pip, python-dev, pyhton-eventlet, python-routes, pyhton-webob, and python-paramiko on it. I uploaded this image to the glance. I wanted to delete the uploaded image for some reson, but glance couldn't delete it. In fact glance deleted the image but did not change its status to deleted. After facing this problem, my nova cannot create an instance. My attempts to lunch an instance lead to the following error message:

ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-273c3006-846a-4e3c-bac3-3325b1973dfa)

I checked all nova and neutron agent lists. They all are working fine. I reinstalled rabbitmq, and checked my nova.conf for any problem. None of them worked for me. I also check different nova log file and just just found an error in my nova.api log:

2016-09-07 20:48:27.247 20065 ERROR nova.api.openstack [req-94a5eaab-cce7-4b26-b895-a83edf02bb5c None] Caught error: id

Any help would be highly apreciated.
