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 ------------ 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 2012-08-29 09:14:45 CRITICAL nova [-] global name 'self' is not defined 2012-08-29 09:14:45 TRACE nova Traceback (most recent call last): 2012-08-29 09:14:45 TRACE nova File "/usr/bin/nova-compute", line 49, in <module> 2012-08-29 09:14:45 TRACE nova service.wait() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 413, in wait 2012-08-29 09:14:45 TRACE nova _launcher.wait() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 131, in wait 2012-08-29 09:14:45 TRACE nova service.wait() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/eventlet/greenthread.py", line 166, in wait 2012-08-29 09:14:45 TRACE nova return self._exit_event.wait() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/eventlet/event.py", line 116, in wait 2012-08-29 09:14:45 TRACE nova return hubs.get_hub().switch() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/eventlet/hubs/hub.py", line 177, in switch 2012-08-29 09:14:45 TRACE nova return self.greenlet.switch() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/eventlet/greenthread.py", line 192, in main 2012-08-29 09:14:45 TRACE nova result = function(*args, **kwargs) 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 101, in run_server 2012-08-29 09:14:45 TRACE nova server.start() 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/service.py", line 174, in start 2012-08-29 09:14:45 TRACE nova self.manager.update_available_resource(ctxt) 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2409, in update_available_resource 2012-08-29 09:14:45 TRACE nova self.driver.update_available_resource(context, self.host) 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py", line 1934, in update_available_resource 2012-08-29 09:14:45 TRACE nova 'memory_mb': self.get_memory_mb_total(), 2012-08-29 09:14:45 TRACE nova File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py", line 1711, in get_memory_mb_total 2012-08-29 09:14:45 TRACE nova meminfo = self._conn.getInfo()[1] 2012-08-29 09:14:45 TRACE nova NameError: global name 'self' is not defined 2012-08-29 09:14:45 TRACE nova ------------------------
