Open Stack

I am using a mysql database.
I tried yesterday to re-install all nova services (just to identify the
source of the problem). So, I noticed that nova-compute is the failed
service. It does not restart when I set the "libvirt_type" to xen at the
nova-compute.conf file. Actually I am using an Ubuntu  server 12.04 with
Xen and I installed the packaged version of nova-services.
Here are the errors that I got at the nova-compute.log
