Open Stack

Hi all,

I got these errors when trying to boot an image. There are related to
glance. I install openstack on an Ubuntu 12.04 (with Xen Server).
Dom0 runs nova-api, glance service, nova-scheduler, nova-cert and
nova-console.
DomU runs nova-compute and nova-network.

Do I have to install glance service on DomU????

Here are log errors (picked from nova-compute.log).
