Your xapi.d plugin (specifically the glance plugin) is failing to download the tarball from glance (probably in nova/plugins/xenserver/xenapi/etc/xapi.d/plugins/glance.py:474 in trunk).

The KeyError seems to indicate that glance doesn't have an image with that image id (don't have the glance code in front of me). However, it could be something else. 

What SR are you using ? You may want to look in your XCP logs to find out what Dom0 is doing on this download.
