I am using a mysql database. <div>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.</div>
<div>Here are the errors that I got at the nova-compute.log</div><div>------------</div><div>2012-08-29 09:14:45 DEBUG nova.utils [req-4908690d-b61f-497d-a5d9-3265ca7869a1 None None] backend <module 'nova.db.sqlalchemy.api' from '/usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/api.pyc'> from (pid=2641) __get_backend /usr/lib/python2.7/dist-packages/nova/utils.py:658</div>

I have had problems using nova-manage db sync when using sqlite and the packaged version of sqlalchemy. If you are trying to do this, you probably need to do a sudo pip install -U sqlalchemy<br>
