Title:
NOVA report "Unexpected API Error" on Newton while run "Nova list"
Status in OpenStack Compute (nova):
Invalid
Bug description:
Description
===========
While run "nova list" to get instance list, NOVA report "[root@ARCHS22K8144
httpd]# nova list
ERROR (ClientException): Unexpected API Error. Please report this at
http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
<class 'sqlalchemy.exc.OperationalError'> (HTTP 500) (Request-ID:
