Open Stack

Hi all,

I used devstack to install openstack on an ubuntu 12.04 with xcp.
I followed this link:
https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md
The script installed almost everything. The dashboard is working and shows
that all services are running.
However, launching "nova-manage service list" shows that nova-compute is
not working.
I also was unable to launch an instance from the dashboard and command line.
Here are errors shown by nova-compute.
Is there any way to solve this problem?
